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

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 a

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

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. . During this period, there were indeed many foreign friends who came to negotiate business and expressed great interest in the products of the company. As the first round of the Fujian-Taiwan exchange, the innovative function is well-known to the industry. For more than ten years, the company has been devoted to the development and production of absolute encoders and absolute multi-turn encoders, from absolute manufacture of absolute encoders to absolute The value encoder has been created in China, silently working hard, keeping improving, possessing a number of patented encoder technology patents, owning independent brands

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 e

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 powe

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 conditio

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 bo

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

Talking about the principle of encoder correctly understanding the encoder Encoder does not seem to bring obvious advantages in the analog monitoring system, but in the network monitoring system, the encoder has set up a bridge between monitoring storage and transmission. In the face of different monitoring architectures, the encoder did not exert its original strength. So now let's talk about the principle of the encoder. The IP-based video surveillance system has many advantages, in which the image quality is improved by at least 30% over the analog system. Network scalability and operating costs are lower, and more convenient is that users can control the management through the computer. Obviously, these are not available in analog CCTV surveillance systems. IP video improves picture quality, improves management, and reduces system operating costs. In addition, it also provides a future-oriented platform, and good network technology is always ready for the megapixel and HD era. The video encoder converts the signal input from the analog camera into a digital video stream. Common compression standards such as M-JPEG, MPEG-4 or H.264 output video formats will be the same and can be fully integrated into network cameras and networks. Video system. Codec also built-in features include video motion detection, tamper alarms, and video analysis. Considering that the average service life of analog surveillance cameras is 5-7 years, many people think it is quite a long time. Some
