| 摘 要： | 采用链型等效电路,对影响启动的高次谐波建立谐波等效电路,推导出参数的计算公式,通过分析和计算,绘制出鼠笼式异步电机的转矩-转差率(T-s)曲线,为电机设计和绕组选择提供评估参考.仿真结果表明即使高次谐波含量很小,也可能造成较大的转矩下凹,从而影响启动.

| Abstract: | A separate equivalent circuit for every high order harmonic wave affecting the starting of the machines was constructed by using chain equivalent circuit and the calculating formulas of the parameters in the equivalent circuit were deduced.Torque-slip(T-s) curve was drawn through the analysis and simulation to provide the motor design and winding selection with an evaluation method.Simulation result shows that high order harmonic wave may bring a huge decline in a T-s curve to make the machine hard to start even though its magnitude would be small. |
