Where is the linear motor-driven electric washing machine? Today's electric drying racks are usually driven by linear motors, while the previous electric drying racks used ordinary rotating electric machines. Why? Where is the linear motor driven transmission? let's see it together. (1) The linear motor-driven transmission does not require any conversion device to directly generate thrust. Therefore, it can eliminate the intermediate conversion mechanism, simplify the entire device or system, ensure operational reliability, improve transmission efficiency, and reduce manufacturing. Cost and easy to maintain. According to foreign data reports, there was a washing machine with a linear motor that worked continuously for 24 hours every day for 24 hours without any maintenance. (2) The ordinary rotating electric machine is limited by the centrifugal force, and its peripheral speed is limited. When the linear motor is running, its components and transmissions are not subjected to centrifugal force like the rotating electric machine, so its linear speed can be avoided. limit. (3) The linear motor directly generates linear electromagnetic thrust through electric energy. In the driving device, it can move without mechanical contact, so that the transmission parts are not worn, thereby greatly reducing the mechanical loss, such as a linear motor driven maglev train. That's it. (4) The rotating electric machine converts the rotary motion into a linear motion through a conversion mechanism such as a steel rope, a rack, a belt, etc., in the operation of the conversion mechanism, the noise is unavoidable, and the linear motor is operated by the electromagnetic thrust driving device. Therefore, the entire device or system has little or no noise and a good operating environment. (5) Because the linear motor has a simple structure, and its primary core can be sealed with epoxy resin or the like after being embedded, it can be applied in some special occasions, for example, it can be used in wet or even water; it can be corrosive. It can be used in gas or toxic or harmful gases, and can be used at high temperatures of several thousand degrees or low temperatures of several hundred degrees.

Application of linear motor on high speed machine tools With the development of direct drive technology, the comparison between the linear motor and the traditional "rotary servo motor ball screw" drive mode has attracted industry attention. Now some of the world's most advanced machining center manufacturers are beginning to apply on their high-speed machine tools. In terms of accuracy, the linear motor has a simple reduction of the interpolation hysteresis due to the transmission mechanism. The positioning accuracy, the reproduction accuracy, and the absolute accuracy are higher than the "rotary servo motor ball screw" by the position detection feedback control, and are easy to implement. Linear motor positioning accuracy can reach 0.1μm. "Rotary servo motor ball screw" up to 2~5μm, and requires CNC-servo motor-no-gap coupling-thrust bearing-cooling system-high-precision rolling guide-nut seat - Workbench closed-loop The transmission part of the whole system should be lighter and the grating accuracy should be high. If you want to achieve high stability, the "rotary servo motor ball screw" should be driven by two-axis. The linear motor is a high-heating component, and it needs to adopt strong cooling measures. To achieve the same purpose, the linear motor has to pay a higher price. In terms of speed, the linear motor has considerable advantages. The linear motor speed reaches 300m/min and the acceleration reaches 10g. The ball screw speed is 120m/min and the acceleration is 1.5g. From the comparison of speed and acceleration, the linear motor has considerable The advantage, and the linear motor will further improve the speed after successfully solving the heating problem, and the "rotary servo motor ball screw" is limited in speed and it is difficult to improve more. In terms of life, the linear motor has a mounting gap between the moving part and the fixed part, has no contact, and is not worn by the high-speed reciprocating motion of the mover. The long-term use has no change in the positioning accuracy of the motion, and is suitable for high-precision occasions. The ball screw can not guarantee the accuracy in high-speed reciprocating motion. Because of high-speed friction, the screw nut will wear and affect the accuracy of the motion. The demand for high precision cannot be met.

In the information technology era, security products have attracted more and more attention. In network monitoring systems, encoders are the bridge between monitoring storage and transmission. Rotary encoder is a common encoder, commonly used in monitoring video transmission equipment, speed measuring generators and other security products, used to measure the speed and with the PWM technology can achieve fast speed device, photoelectric rotary encoder through photoelectric conversion The output shaft angular displacement, angular velocity and other mechanical quantities can be converted into corresponding electrical pulses for digital output (REP). Rotary encoders are divided into single output and dual output. The technical parameters mainly include the number of pulses per revolution (tens to several thousand), and the supply voltage. Single output means that the output of the rotary encoder is a set of pulses, while the dual-output rotary encoder outputs two sets of pulses with 90-degree phase difference between A and B. Through these two sets of pulses, not only the rotation speed but also the rotation can be determined. The direction. Rotary encoder installation techniques are also very particular about, such as improper operation is likely to lay hidden security risks, the following we understand the installation of rotary encoder related issues. Do not apply direct impact to the shaft during installation The connection of the encoder shaft to the machine should use a flexible connector. When installing the connector on the shaft, do not press hard. Even if the connector is used, special attention must be paid to the fact that the shaft may be loaded with a larger load than the allowable load due to poor installation, or the core removal phenomenon may occur. The bearing life depends on the conditions of use and is particularly affected by the bearing load. If the bearing load is smaller than the specified load, the bearing life can be greatly extended. Do not disassemble the rotary encoder. Doing so will impair oil and drip resistance. Anti-drip products should not be immersed in water or oil for a long time, and should be wiped clean when there is water or oil on the surface. Vibration can cause false impulses The vibration added to the rotary encoder is often the cause of false pulses. Therefore, pay attention to the installation site and installation site. The greater the number of pulses per revolution, the narrower the slot spacing of the rotating slot disc, the more susceptible to vibration. When rotating or stopping at a low speed, the vibration applied to the shaft or the body shakes the rotating groove disc and false pulses may occur. Wiring connection pay full attention to <br> <br> Incorrect wiring may damage the internal circuit, it should give full attention to the wiring: 1. The wiring should be performed with the power OFF. When the power is turned on, if the output line contacts the power supply, the output circuit may be damaged. 2. If the wiring is incorrect, the internal circuit may be damaged, so pay attention to the polarity of the power supply when wiring. 3. If the wiring is conducted in parallel with the high-voltage line or the power line, it may be induced to malfunction and be damaged. Therefore, separate the wiring. 4. When extending the wire, it should be less than 10m. Moreover, due to the distribution capacity of the electric wire, the rise and fall time of the waveform will be longer. When there is a problem, the waveform is shaped using a Schmidt circuit or the like. 5. To avoid induced noise, etc., try to use the shortest distance wiring. When inputting to an integrated circuit, special attention needs to be paid. 6. When the wire is extended, the rise and fall times of the waveform are prolonged due to the influence of the conductor resistance and the line capacitance, and interference (crosstalk) between the signals is likely to occur. Therefore, a wire with a small resistance and low capacitance between the wires (twisted pair) is used. Shielded wire). For HTL encoders with a symmetrical negative signal output, the signal transmission distance can reach 300 meters.

June 15th to 17th, 2011, Ginpo Electromechanical Co., Ltd. held a ceremony in the IAC TME Sensor Exhibition of Shanghai New International Expo Center based on the traditional Chinese method to invite Japanese and American brands in Europe and the United States to exchange ideas with a view to inspiring independent innovation of domestic automation industry product manufacturers. With the determination of improving product quality, China's absolute value multi-turn encoders have challenged European and American brands. During the exhibition, although the weather was not beautiful and the rain continued, the visitors to the exhibition were more or less affected by the slightest shrinkage, but the audience standing in front of the Jingpu Electromechanical booth was still bustling, carrying out technical exchanges, product consultations, and even speculation. .

Servo motor phase and encoder position adjustment The mainstream servo motor position feedback components include incremental encoders, absolute encoders, sine and cosine encoders, and resolvers. Phase Alignment of Incremental Encoders In this discussion, the output signal of an incremental encoder is a square wave signal, and it can be divided into an incremental encoder with a commutation signal and an ordinary incremental encoder. Ordinary incremental encoders have two-phase orthogonal square-wave pulse output signals A and B, and zero-bit signal Z; in addition to the ABZ output signal, incremental encoders with commutation signals have a mutual difference of 120 degrees. The number of revolutions per revolution of the electronic commutation signal coincides with the number of pairs of magnetic poles of the motor rotor. The alignment of the phase of the UVW electronic commutation signal of the incremental encoder with a commutation signal and the phase of the rotor pole or the phase of the electrical angle is as follows: 1. Use a DC power supply to pass the motor's UV winding with a DC current less than the rated current, U in, V out, and orient the motor shaft to an equilibrium position; 2. Observe the U-phase signal and Z-signal of the encoder with an oscilloscope. According to the convenience of operation, adjust the relative position of the encoder shaft and the motor shaft, or the relative position of the encoder housing and the motor housing; 4. While adjusting, observe the U-phase signal edge of the encoder, and the Z signal until the Z signal is stable at a high level (in this default Z signal, the normal state is at a low level), lock the relative position between the encoder and the motor. Positional relationship; . Rotate the motor shaft back and forth. If the motor shaft retracts to the equilibrium position each time, the Z signal can be stabilized at a high level, and the alignment is effective. After removing the DC power supply, verify the following: Observe the U-phase signal of the encoder and the UV back-EMF waveform of the motor with an oscilloscope; 2. Rotate the motor shaft. The rising edge of the U-phase signal of the encoder coincides with the zero-crossing point of the back-EMF waveform of the motor from low to high. The Z signal of the encoder also appears at this zero-crossing point. The above verification method can also be used as an alignment method. It should be noted that at this time, the phase zero of the U-phase signal of the incremental encoder is aligned with the phase zero of the back EMF of the motor's UV wire. Because the U reverse potential of the motor is different from the UV back-EMF by 30 degrees, After this alignment, the phase zero of the U-phase signal of the incremental encoder is aligned with the -30 degree phase point of the opposite potential of the motor U, and the phase of the electrical angle of the motor coincides with the phase of the opposite potential waveform of the U, so the incremental encoding is now performed. The phase zero of the U-phase signal of the device is aligned with the -30 degree point of the electrical angle of the motor. ^ Some servo companies are accustomed to aligning the zero point of the U-phase signal of the encoder directly with the zero point of the electrical angle of the motor. To do this, you can: 1. Use 3 resistors of equal resistance to connect into star type, and then connect the 3 resistors of the star connection respectively to the UVW three-phase winding leads of the motor; - 2. Using an oscilloscope to observe the midpoint of the U-phase input and star resistance of the motor, the U-reverse potential waveform of the motor can be approximated; According to the convenience of operation, adjust the relative position of the encoder shaft and the motor shaft, or the relative position of the encoder housing and the motor housing; 4. While adjusting, observe the rising edge of the U-phase signal of the encoder and the zero-crossing point of the opposite potential waveform of the motor U from low to high, and finally make the rising edge coincide with the zero-crossing point, and lock the relative position relationship between the encoder and the motor to complete the alignment. . ( @1 V-O: a0 |, h Because the conventional incremental encoder does not have UVW phase information, and the Z signal can only reflect one point in a circle, it does not have direct phase alignment potential and is therefore not The topic of this discussion. Absolute Encoder Phase Alignment Absolute Encoder Phase Alignment For single-turn and multi-turn applications, there is little difference. In fact, the alignment phase of the encoder is aligned with the phase of the motor's electrical angle within one turn. Early absolute encoders would give the highest bit level of a single-turn phase as a single pin. Using the 0 and 1 flip of this level, the phase alignment between the encoder and the motor can also be achieved as follows: Using a DC power supply to the motor's UV winding to pass less than the rated current of DC, U into, V out, the motor shaft orientation to a balanced position; 2. Observe the highest count bit level signal of the absolute encoder with an oscilloscope; According to the convenience of operation, adjust the relative position of the encoder shaft and the motor shaft, or the relative position of the encoder housing and the motor housing while adjusting, while observing the edge of the highest count signal until the edge of the motor appears accurately in the motor. The position of the shaft is balanced, and the relative positional relationship between the encoder and the motor is locked; 5. Turn the motor shaft back and forth, and if the motor shaft can return to the balance position each time it is free to return to the balance position, the alignment will be effective.

The rotary incremental encoder outputs a pulse when it is rotated, and its position is known by the counting device. When the encoder is not moving or power is off, the internal memory of the counting device is used to remember the position. In this way, when the power is off, the encoder can't have any movement. When the caller works, the encoder can not interrupt and lose the pulse during the output pulse. Otherwise, the zero point of the counting device will shift, and this bias The amount of shift is unknown, and only the wrong production result can be known. The solution is to increase the reference point, and the encoder corrects the reference position into the memory position of the counting device every time the encoder passes the reference point. Before the reference point, the accuracy of the position cannot be guaranteed. For this reason, in the industrial control, there are methods such as finding a reference point for each operation, and starting to change the zero. For example, the positioning of the printer scanner is the incremental encoder principle. Every time we turn it on, we can hear a bang, it is looking for the reference zero, and then it works. This method is more troublesome for some industrial control projects, and even does not allow booting to change to zero (you must know the exact position after booting), so there is an absolute encoder. Absolute rotary photoelectric encoders have been widely used in angle, length measurement and positioning control in various industrial systems because of their absolute uniqueness, anti-interference and no need for power-down memory. There are many scribe lines on the absolute encoder optical disc. Each line is followed by 2 lines, 4 lines, 8 lines and 16 lines. Orchestration, so that at each position of the encoder, by reading the pass and dark of each reticle, a set of unique binary codes from the zeroth power of 2 to the n-1 power of 2 is obtained (Gray Code), this is called an n-bit absolute encoder. Such an encoder is determined by the mechanical position of the code wheel and is immune to power outages and interference. Absolute encoder uniqueness of each position determined by the mechanical position, it does not need to remember, no need to find a reference point, and do not have to count all the time, when you need to know the position, when to read its position. In this way, the anti-jamming characteristics of the encoder and the reliability of the data are greatly improved. Since absolute encoders are significantly superior to incremental encoders in positioning, they have been increasingly used in industrial positioning. Due to its high precision, the absolute encoder has a large number of output bits. If parallel output is still used, each output signal must ensure that the connection is good, and it is isolated for more complicated working conditions, and the number of connecting cable cores is large. It brings a lot of inconvenience and reduces reliability. Therefore, the absolute encoder is a serial output or a bus type output in the multi-digit output type. The most commonly used serial output of the absolute encoder produced in Germany is SSI (synchronous string). Line output). Rotating a single-turn absolute encoder from a single-turn absolute encoder to a multi-turn absolute encoder to measure each line of the optical encoder in rotation to obtain a unique code. When the rotation exceeds 360 degrees, the code is returned. To the origin, this does not conform to the principle of absolute coding. Such an encoder can only be used for measurements within a range of 360 degrees, called a single-turn absolute encoder. If you want to measure the range of rotation over 360 degrees, you need to use a multi-turn absolute encoder. The encoder manufacturer uses the principle of the watch gear mechanism. When the center code wheel rotates, another set of code wheels (or sets of gears, multiple sets of code disks) is driven by the gear, and the number of turns is increased on the basis of the single-turn coding. Encoding to expand the measuring range of the encoder, such an absolute encoder is called a multi-turn absolute encoder, which is also determined by mechanical position determination, and each position code is unique and does not need to be memorized. Another advantage of the multi-turn encoder is that due to the large measurement range, the actual use is often more affluent, so that it is not necessary to find a zero point during installation, and an intermediate position is used as a starting point, which greatly simplifies the difficulty of installation and debugging. Multi-turn absolute encoders have obvious advantages in length positioning and have been increasingly used in industrial positioning.

Application of High Precision Rotary Encoder in Servo Feedback Positioning Sys It is basically a double brush orthogonal unbounded potentiometer. It has a temfull circular ring of resistive material that is electrically connected at both ends where two electrically independent brushes move. The two brushes are mechanically connected to each other by a 90° angle. Rotary encoders are often used in positioning systems with servo feedback. In this case, the cost of the encoder is generally not important. However, the encoder can also be used to encode the position of knobs on some user interfaces, such as the volume knob on an audio system. For these knobs, potentiometers can be selected for low-cost, high-precision, and absolute-reading values, but their travel is limited, typically to less than 340°, or optomechanical rotary encoders are available. Their travel is not limited, but the price High, low accuracy, only relative readings. This design example attempts to combine the two, with the advantages of the potentiometer, as well as the characteristics of the optical machine rotary encoder boundaryless operation. The encoder uses the structure technology of the standard potentiometer, so it is easy to produce. It is basically a double brush orthogonal unbounded potentiometer. It has a full circular ring of resistive material that is electrically connected at both ends where two electrically independent brushes move. The two brushes are mechanically connected to each other by a 90° angle (Figure 1). The ADC in the microcontroller reads the two signals and the firmware uses these two signals to determine the quadrant in which the axis is located. Once you know the quadrant, you can use the two brush signals to calculate the axis position. When the brush reaches the power connection, this signal should be ignored due to the non-linear response (Figure 2). There is a 90 degree angle between the two brushes, so it is not possible to be in a non-linear position at the same time. Today, even the most basic microcontrollers will have a 10-bit ADC, so the two signals have a total of 11-bit resolution, or better than 0.2°. If the application does not require an absolute reading or a software reset, the microcontroller can ignore it. This quadrature vertexless potentiometer provides an experience similar to the old tuning knob on a classic analogue radio. It offers new possibilities for human-machine interface design, enabling consumer products to gain a noble sense at low cost.

You will find permanent magnets in many products, such as televisions, telephones, computers, audio systems and automobiles. The permanent magnet family consists, in general terms, of non-rare earth permanent magnets and rare earth magnets. The non-rare earth magnets include AlNiCo (Aluminum-Nickel-Cobalt) magnets and Ceramic (Strontium and Barium Ferrite) magnets. Rare earth magnets include Sm-Co (Samarium-Cobalt) magnets and NdFeB Magnet (Neodymium-Iron-Boron). Although non-rare earth magnets are used in the majority of these applications due to their economic cost, rare earth permanent magnets have many distinguishing characteristics, such as a large Maximum Energy Product, (one performance index for permanent magnets). Dozens of magnetic materials which contain rare earth have been developed recently. Two major families of rare earth permanent magnets, Sm-Co magnets and NdFeB magnets, have been widely used in a variety of applications. Each family has its own advantages and disadvantages. We can provide almost all grades of permanent motor magnets in large quantity.

BQH24 Mine Intrinsically Safe Encoder / Mine Encoder 1. Use and scope of use In the mine automation system can not be separated from the speed closed-loop control. Especially in mine hoists and dual-use belt conveyors that require high speed feedback, speed closed-loop control is used to enhance system operation reliability. For this reason, BQH24 mining intrinsically safe encoders are indispensable in closed-loop control or speed protection devices. The mine shaft encoder can be used together with the mine winch, belt conveyor electrical control device, and can also be used alone as a winch and belt conveyor speed measuring device and protection device. 2.

Structural characteristics and working principle a) Encoder housing is manufactured from Ф75's garden steel. A transmission shaft is output on one side of the housing and is connected with the output shaft of the motor or other related rotating mechanisms. The center of gravity of the encoder installation coincides with no cracks, complete cables, and neat end points of the interface. b) Another inlet of the housing is provided with an inlet nozzle for external connection. c) The encoder is an optical encoder. There are four external lines, which are +24V, 0V, A, B, respectively. The encoder uses the principle of photoelectric conversion to output two groups of square-wave pulses A and B; A, B The two groups of pulses have a phase difference of 60°. d) When the axis of the photoelectric encoder rotates, both A and B lines will generate pulse output. The two phases A and B will have a phase difference of 60 degrees, which can measure the rotation direction of the photoelectric encoder. If the A-phase pulse is ahead of the B-phase pulse, the photoelectric encoder is forward, otherwise it is reversed. working principle The photoelectric encoder consists of a grating disk and a photoelectric detection device. The grating plate is opened on a certain diameter of a circular plate and several rectangular holes are equally divided. Since the photoelectric encoder disk is coaxial with the motor, when the motor rotates, the grating disk and the motor rotate at the same speed, and a detection device composed of an electronic element such as a light emitting diode detects and outputs a plurality of pulse signals, and the number of output pulses of the photoelectric encoder per second is calculated. Can reflect the current motor speed. 9. Installation and wiring (see Table 1 for details ) Table 1 1. This product is used in circuits that pass the intrinsically safe test. 2.

Encoder introduction An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a form that can be used for communication, transmission, and storage. The encoder converts the angular displacement or the linear displacement into an electrical signal. The former is called a code wheel, and the latter is called a code wheel. According to the readout mode, the encoder can be divided into two types: contact type and non-contact type. Contact type uses brush output. A brush contacts the conductive or insulating region to indicate whether the state of the code is "1" or "0"; the non-contact receiving sensitive component is a photosensitive component or a magnetic sensing component, and the light transmitting region is opaque when the photosensitive component is used The light zone indicates whether the state of the code is "1" or "0". The binary signal of "1" and "0" is used to convert the collected physical signal into machine code readable electrical signal for communication, transmission and store.

According to the Yonhap News Agency, South Korea's consumer electronics and home appliance manufacturing company LG Electronics announced on Monday that its variable-frequency direct-drive (DD) washing machine motor has been launched since 1998, and the cumulative output has reached 70 million units. Image from Yonhap News Agency website According to LG Electronics, variable frequency direct drive motors can significantly reduce the noise and vibration of the washing machine by directly connecting the motor to the load, and can achieve higher durability and energy efficiency. LG said that half of its DD direct-drive motor production comes from the Changwon plant, which is located 398 kilometers south of Seoul. The plant's annual production of DD motors reached 1 million units in 2005. Since then, this figure has grown dramatically, reaching a huge production of 8 million units in 2017 alone. LG further stated that the total length of the cable used in the 70 million DD motors is equivalent to 22 round trips from the Earth to the Moon. LG said that its variable frequency direct drive motor has been certified by global authoritative organizations, including German VDE certification. LG said that its ability to produce its own DD motors has made the market a favorite for more than 20 years. The technology company said that the company's ongoing research has produced the fourth-generation inverter direct-drive DD motor, while the fourth-generation cost is only a quarter of the first-generation DD motor in 1998. These cost-reduction efforts have helped LG Electronics produce high-quality variable-frequency direct-drive motors. [We intend to install high-quality components with high performance on more home appliances so that our customers can experience the latest advantages of this technology," LG Electronics said.

Encoder market Encoders have a high proportion of applications in the OEM market, mainly used in machine tools, elevators, servo motor accessories, textile machinery, packaging machinery, printing machinery, lifting machinery and other industries. In 2010, the rapid growth of China's OEM market drove the rapid growth of the encoder market. In 2010, the market size of the Chinese encoder market reached 1.3 billion yuan, a year-on-year increase of 42.9%. From the industry point of view, elevators, machine tools and servo motors are the key application areas of encoders, accounting for 53% of the overall application market. Textile machinery, packaging machinery and printing machinery and other fields currently have a small market share. Encoders generally do not directly enter these three industries. The competition of encoder manufacturers mainly focuses on the motor production plants that provide servo motors for these machinery industries. The current market share of lifting machinery is also small, accounting for only 4%-5%. In project-oriented industries such as the metallurgical and electronics industries, encoders currently have a lower proportion of applications, accounting for only 14% of the market. In addition, encoders have certain applications in medical machinery, wind power, automobile production lines, hybrid vehicles, water conservancy, rail transit, etc., but the application ratio is low. In 2010, the demand for automation products in the wind power industry has increased by more than 50%, and the main application fields of elevators, servo motors, textile machinery and machine tools have also grown significantly, which is the main source of growth. From the perspective of manufacturers, the current European and American brands occupy the high-end market, accounting for more than one-third of the market share, product prices are high-end, and have advantages in new energy fields such as heavy industry and wind power; Japanese and Korean brands mainly occupy the mid-end market, accounting for three More than one market share, product price positioning in the middle, in elevators, machine tools, servo motors and other industries are widely used; while mainland companies mainly participate in the competition in the low-end market, the product price is lower, to account for nearly half of the market The volume only gets 25% of the mainland market share. Companies with high market share include Heidenhain, Tamagawa, Nemicon, Yuheng, Baumer, Rep, P+F, Danaher, Koyo, Omron, etc. The market share of the top three companies accounts for nearly 50% of the total market, and the market concentration is high. The application industries that are mainly targeted by enterprises are highly concentrated and the industry is less competitive. The growth rate of mainstream manufacturers also has a significant gap, with the largest increase of 60% and the smallest increase of less than 10%. The encoder is divided into absolute value type and incremental type. At present, the price of absolute encoders is about 4 times that of incremental encoders. 70% of the applications in the domestic market are incremental encoders with relatively economical price, mainly used in industries such as packaging, textiles, elevators, etc. It is required to measure the speed and the equipment that is not required for absolute position measurement. In high-precision mechanical equipment or heavy industry such as steel, port and lifting, due to the relatively high precision of measurement, more absolute encoders are used. In these heavy industry applications, due to the harsh working conditions, the requirements for the impact resistance and vibration of the encoder are high. With the improvement of automation of mechanical equipment, the application fields of encoder products are more and more extensive, and customers are no longer satisfied that the encoder can only convert physical rotating signals into electrical signals, and requires higher integration of encoders. The product is more durable and it is expected to have a richer interface in the absolute encoder to make more devices intelligent. At present, production safety and communication security in the entire industrial market are getting more and more attention. At the national level, the requirements for product safety performance are also put forward. Encoders also have corresponding specifications for safety standards, but the domestic encoder market has relatively strict technical requirements for products. Low, customers prefer middle and low-end products.
