| 一、 | 产品概述product overview | |||||||||
| 在商用车助力转向应用中，创伟开发了系列永磁同步驱动系统（PMSM），用于替代原有的交流异步电机。PMSM电机比异步电机体积大幅减小，重量大幅下降，同时系统效率显著高于异步电机。PMSM也无需异步电机的风扇冷却，电机的噪音大幅下降 In the application of power steering for commercial vehicles, CW developed the permanent magnet synchronous drive system(PMSM). It is used to replace the AC asynchronous motor. The volume of the PMSM motor is much smaller than the AC asynchronous motor.The weight of the motor is much lighter.The system efficiency is much higher than the AC asynchronous motor.The PMSM doesn't need the fans to cooling. The noise dropped dramatically. |  | |||||||||
