CRRC Zhuzhou locomotive released the 400 km / H grade "permanent magnet high speed railway" motor

On October 18, CRRC Zhuzhou Motor Co., Ltd. recently released the tq-800 permanent magnet synchronous traction motor for 400 km / h high-speed EMU. This product marks the first time that China's high-speed railway power has built a technical platform for permanent magnet traction motor products with a speed of 400km / h, which fills in the technical gap in China. Today, the reporter of Sanxiang Metropolis Daily saw its true appearance in CRRC Zhuzhou Electric Co., Ltd.

"permanent magnet high-speed motor" adopts new closed air cooling and directional cooling technology for key parts, which ensures the internal cleanness of the motor and effectively balances the temperature of all parts of the motor; adopts new rare earth permanent magnet material, which effectively solves the problem of permanent magnet demagnetization; combines the advantages of insulation structure of high-power locomotive and high-speed iron traction motor, which has a higher absolute value. Edge reliability.

"compared with the traditional asynchronous traction motor, it has higher power density, higher efficiency, stronger environmental adaptability, lower life cycle cost and other comparative advantages." Zou Hu, the traction motor business unit of CRRC Zhuzhou Motor Co., Ltd., said. Reporter

also learned that the performance indexes of the permanent magnet synchronous traction motor reached the international advanced level, and it will be used to drive the key research and development project of our country - 400 km / h transnational interconnection high-speed train.
