摘要
本文根据电磁场理论,用统一的方法,建立了电机瞬变过程与横振、扭振相耦联的微分方程,经过变换得到了常系数无因次状态方程,进行了数字计算,得到了启动过程的横振、扭振、径向电磁力及电磁力矩等的变化规律。理论结果和实验结果相吻合。
According to the electromagnetic field theory, a set of differential equations昳s derived for coupling the transient process for an electrical machine with the traverse and tor-sional vibrations for the rotor, by using a unified method. A non-dimensional state equation with constant coefficient is obtained by transformation. Computation is done. Rules of the change are obtained for tranverse and torsional vibration, radial magnetic force, electromagnetic torque, and so on in the starting process. The theoretical results are shown to be in good agreement with the experimental one.
