The key technology of servo motor development direction modern servo motor is no longer an independent component that simply performs tasks, but an integrated system. It can be said that modern servo motor is the nerve center of the whole electromechanical system. Modern motors can provide energy for the whole electromechanical system, which means that modern motors are the power center; Modern motors can also adjust, balance and control the entire electromechanical system. Even many modern motors combine these two functions. Such powerful and comprehensive functions will inevitably put forward higher requirements for modern motors. These requirements are not only reflected in the design and production of modern motors, but also in the economy, applicability and development of products produced by modern motors. Six development directions of modern servo motors 1. From brush to brushless, the coverage rate of traditional DC motors is very high, mainly because most power supplies are DC. The traditional DC motor is painted. Brush Motor refers to a motor that is automatically completed through the cooperation of commutator and brush. Commutator and brush are installed in the motor. Although the Brush Motor is technically mature in production, the corresponding accessories are relatively cheap, but there are many shortcomings in the brush motor. For example, the process of replacing accessories is troublesome, the service life of accessories is short, the heating rate is high, the reversing spark is large, the loss is serious, and the electromagnetic interference is serious. Therefore, although Brush Motor has many advantages, it is gradually replaced by brushless motor with the passage of time. Brushless DC Motor is composed of motor body and driver, and is a typical electromechanical integration product. There are many types of brushless motors, and Brush Motors have almost no disadvantages. Brushless Motor has low wear, low noise and low interference. It can be said that brushless motor has great advantages over Brush Motor. 2. Direct drive modern servo motors modern motors usually operate at high speed. They can run at hundreds or even thousands of revolutions per minute. It is relatively difficult to change high speed and low speed at high operating speeds, but many applications have such requirements. . Therefore, modern motors need to provide accessory systems for switching speeds. However, this conversion system will inevitably increase the size of the entire motor system and will also affect the accuracy and efficiency of the equipment. At this time, only through modern motor drive can the development be directly driven, and this problem can be effectively solved. 3. Speed of servo motor the development of modern industry usually requires extremely high speed of motor, that is, it usually requires motor to maintain very high or very low speed. The requirement for the speed of modern motors is closely related to the direct drive of motors. The extremely fast speed of the motor not only helps to realize the direct drive of the motor, but also improves the working efficiency of the motor and the accuracy of the equipment. 4. From uniform speed to speed change, traditional motors basically maintain speed, and most Motors only have one switch for on/off. However, in actual operation, the speed of the motor needs to be adjusted. In this process, frequent switching on the motor will inevitably lead to wear of the internal components of the motor, which will also have a certain impact on the controller and the power grid. . Therefore, the use of speed control function plays a vital role in the whole motor system. For example, modern inverter air conditioners use speed control methods. This method is more comfortable than traditional air conditioners, and this speed control system enables the motor to work more effectively and save electricity. 5. The transition from large-scale to miniaturization and miniaturization modern industry is increasingly in need of miniaturization and miniaturization of motors, especially portable products that require higher requirements for motor size. For example, the transition from the first generation of electronic computers to desktop computers to notebook computers to iPad and mobile phones reflects the demand for miniaturization and miniaturization of electric motors. However, in order to realize the transition from large to small, the power of the basic components must be increased, and the performance of the basic components and the principle of motor operation should be improved. 6. Intelligentization. In today's society, electronic information technology is changing with each passing day, and intelligent systems permeate all aspects of our lives. Modern motors not only provide power for the whole electromechanical system, but also have the functions of balance and advertisement, etc. TAG servo motor, motor, servo motor, servo
