摘要
应用电路理论分析断相瞬间三相异步电动机绕组电压的过渡过程和高频振荡过电压的产生，经过推导得出绕组电压的数学模型、变化曲线和影响因素。
Based on circuit theory,the interim course of winding voltage of three phases asynchyonous motor when its phase was broken and the forming of high frequency oscillating overvoltage were analysed in this paper.It were showed that the mathematics formula and changing curve and influence factors.A simple and reliable motor phase-broken protecting circuit was designed.
