有刷直流电机振动转矩的解析与实验研究

为了验证和剖析有刷直流电机振动转矩存在的客观性，采用角加速度测速发电机进行了振动转矩的检测，实验表明，有刷直流电机负载运行时存在明显的振动转矩。从元件的换向过程和气隙磁场的分布进行了分析和仿真，表明这两者是产生振动转矩的主要原因。

Analysis and Experiment Research of Vibration Torque for Brush DC Motor

In order to verify and analyze the objectivity of vibration torque existence in brush DC motor, the vibration torque was detected by angular acceleration tachometer generator. The experiments results show that brush DC motor has obvious vibration torque when running with load. The air gap magnetic field distribution and commutation process of elements were analyzed and simulated, the results show they are the main causes of vibration torque produced in the brush DC motor.
