[0002] No matter in the field of daily life or industrial application, the application of electric motors is ubiquitous, ranging from aerospace to small to electric fans, etc., there are a wide variety of electric motors, many fields require the position, speed, The power is precisely controlled to ensure that the motor operates at the rated maximum power. Therefore, in the face of complex motor systems, in order to reduce the drive cost and application difficulty of motors and servo motors, it is particularly important to use servo motors with universal compatibility. Therefore , there is a lack of a servo motor drive system that can meet various needs in the market today

Most of the motors in the market today are old-fashioned controls, both in terms of control accuracy and control safety, there are serious deficiencies. In addition, due to the simplicity of the control chip and the control circuit, the position signal of the servo motor and the In terms of the running stability of the motor, there are also disadvantages of inaccurate position and poor running stability. Therefore, there is a lack of a processor chip with low power consumption and superior performance to control the servo motor drive system, which greatly enhances the stability of the motor control motor and the processing speed. As well as control accuracy, most of the servo motor control systems nowadays use a simple acquisition and control single-channel system, and there is no corresponding feedback control measure to reduce the control error, so a high-performance The high-precision control servo motor system has great application value, and has also played a progressive role in national industry and people's life
