| 摘 要： | 分析了三相异步电动机在不对称三相电压下运行性能(电机定子电流、电磁转矩和效率)的变化情况,结果表明,三相异步电动机在不对称电压运行时,至少有一相电流超过额定电流,电机转矩减少和效率降低。总结了不对称电压对电动机危害的一些情况,给出了电机运行时对三相电压对称度的要求。

| Abstract: | The change of three-phase induction motor’ operation characteristics is analyzed and calculated at asymmetrical three-phase voltage, including stator current, electromagnetic torque and efficiency etc. of the motor. The results show that, while at least one phase current is over the rated current, the motor’ torque reduction and its efficiency reduction will decrease. Circs of damaging motor at asymmetrical three-phase voltage are summarized. |
