sync motor

This paper analyzes the control character of sync drive of multi motor. The compensate plan of speed and electric current for multi motor of independence and supple joint are proposed.

本文对多电机同步调速控制的特点进行了分析，提出了对多级独立电机及多级柔性连接电机同步驱动的速度补偿、电流补偿方案。

Then, the researcher analyses and calculates the fatigue life of fuse shaft under different working conditions, such as deadstart, the frequency motor out-sync, bailing out, and typical geological random load.

计算分析了静启动、变频电机不同步、堵转脱困、典型地质的随机载荷工况下保险轴的疲劳寿命，并得出不同工况下保险轴的安全系数、寿命、损伤等随载荷幅值的变化曲线。
