At the end of November, permanent magnet motor with square wave current closed-loop control technology developed by Zhuzhou CSR Electric Locomotive Research Institute is successfully tested and approved on the High-speed Permanent Magnet System Platform. It means TEC has become the first rail transportation traction equipment supplier in the world that masters this core technology.

In the future, this technology is likely to be applied in all areas of the control of High-power Permanent Magnet Motor, thereby enhancing our technological level of permanent magnet motor control and consolidating our world's leading role in the field of permanent magnet system technology.
