Sinoma Pingxiang Cement Co., Ltd.
In March 2022, Thompson Electric Co., Ltd. undertook the transformation of permanent magnet synchronous motors for the energy efficiency improvement of 4500-ton line grate cooler fans of Sinoma Pingxiang Cement Co., Ltd. A total of 12 permanent magnet synchronous motors were transformed. After the transformation, the permanent magnet synchronous motors have remarkable energy-saving effect. The central control can directly monitor the motor winding temperature and bearing temperature, greatly reducing their failure rate. The power saving effect has been highly recognized by the leaders of Zhongcai Pingxiang Cement Co., Ltd.
