摘要
针对复合笼型转子参数随转差率变化导致电动机性能参数难以计算的问题,基于Ansoft MAXWELL有限元软件,建立考虑转子旋转、饱和、涡流效应的"场-路-运动"耦合二维有限元模型,直接计算电动机在不同转差运行下的磁场分布,进而计算电动机性能参数。分析了复合层不同材料和厚度的选取对电动机性能有一定的影响,为电动机的优化设计提供参考依据;通过对电动机性能参数动态变化过程的分析,验证了复合笼型转子结构设计的合理性;通过对比计算结果和实验数据,验证此计算方法满足工程精度要求。
Compound cage rotor parameters vary with slip.To accurately calculate motor parameters,Ansoft Maxwell finite element software is applied in this paper.Two-dimension finite element model coupling field-circuit-motion is set up.Rotor rotation,saturation and eddy current effects are considered.Magnetic field at different slips is calculated directly.Motor performance parameters are obtained.The alloy material and depth have some influence on motor performance,which provides reference for motor optimal design.Based on analysis of motor performance parameters dynamic changes process,reasonableness of compound cage rotor structural design is testified.Compared with analytical and experimental results,the project effectiveness of the calculation method is verified.
