MT4000—Permanent Magnet Synchronous Motor Test System

Case Presentation

  MT4000—Permanent Magnet Synchronous Test System—Product Background


  The application requirements of permanent magnet synchronous motors in various industries, especially in the industrial control industry, are becoming more and more extensive. Three-phase permanent magnet AC synchronous motors must ensure product performance and product quality in product development and factory inspection. Therefore, it is particularly important to conduct strict testing and analysis on the performance of the motor. According to the national standard GBT 22669-2008 "Three-phase Permanent Magnet Synchronous Motor Test Method" and with reference to other national standard requirements and various motor test standards, the system conducts type verification tests on the motor test purpose, test procedures and test methods.
