摘要
通过推导五相混合式电动机在振荡状态时的电磁转矩的基本表达式，研究了电磁阻尼转矩系数随转速变化的特性，揭示了混合式步进电动机的动态不稳定性机理，理论分析与实验结果相符。
The characteristics of the electromagnetic damping-torque coefficient with the change of the rotor velocity are investigated by use of a basic expression of electromagnetic torque of 5-phase hybrid stepping motors under the oscillation, it reveals the principle of the dynamic instability in hybrid stepping motors and has been verified that the analysis of the dynamic instability are corresponding with the experiment.
