摘要
用多传输线理论分析了定子绕组内的电压波传播过程,提出了计算变频牵引电机定子绕组暂态电压分布的等效电路。用有限元软件ANSYS计算等效电路分布参数值的结果表明末端线圈首匝对地电压、匝间电压最大。
An equivalent circuit is developed based on transmission line theory taking account on high-frequency effects. The parameters of equivalent circuit are calculated by the finite element analysis ANSYS software. Then transient voltage distribution in windings of inverter-fed traction motor is calculated by the equivalent circuit. The results show that the maximum voltage across the first turn of end coil and turn to ground voltages of turns are not different.
