Problems solved by technology

[0002] At present, electric drive and drag systems based on servo drives and servo drive motors have been widely used in many fields. The operating performance and service life of the servo drive have a great impact. On the other hand, the operating environment of the servo drive often generates complex electromagnetic interference due to the operation of high-voltage power grids, high-voltage motors and other equipment, resulting in failure of the hardware and software systems of the servo drive. Causes serious interference and affects the reliability of the servo drive equipment operation. In view of this problem, there is currently no professional and effective test method for the electromagnetic compatibility of the servo drive, which greatly limits the operation of the current servo drive equipment. The stability and reliability of the servo drive, and Yan always affected the progress of the research and development technology of the servo drive equipment. Therefore, in response to this problem, it is urgent to develop a new servo drive electromagnetic compatibility detection method to meet the needs of actual use.
