摘要
分析了两种逆变器— 180°导通型和 12 0°导通型输出的非正弦电源作用于电机时产生的磁势谐波 ,给出了电机k次谐波等值电路 ,在此基础上 ,从电流、转矩、损耗等方面讨论了非正弦电源对电机性能的影响。
The motor harmonics of magnetic force and its effects on a motor performances are analyzed when the motor is excited by the non-sinusoidal wave electric powers which are respectively produced by a 180° or 120°turn-on rectifying wave.And then,the effects on the motor performance from the current,the torque,the power loss,etc are studied.
