Design of Structure for Low Voltage Large Current Permanent Magnet DC Motor Used in Traction

牵引用低压大电流永磁直流电机在工作时需要频繁换向,以往是通过外置方向控制器来实现电机的换向,但是由于连接的导线和接触电阻,增加了损耗,降低了电机效率。将方向控制器和电机本体有机结合在一起,提高了电机效率。通过对物理样机的试验,验证了方案的可行性。

The low-voltage high-current permanent magnet DC motor used in traction needed frequent commutation. In the past, the motor commutation through the external direction controller to carry out, but due to the connection of the conductor and contact resistance, increased the loss and reduced the motor efficiency. Combined direction controller and motor body in together, to improve the motor efficiency. Based on the physical prototype test, verified the feasibility of the project.
