摘要
针对双"I"型转子结构的内置式高密度永磁同步电机(PMSM),基于MATLAB/Simulink平台提出了一种变参数等效磁网络法,充分考虑转子漏磁,且通过变参数环节,自动调节各部分磁导率,计算铁心饱和,提高了变参数等效磁网路法的计算准确性。利用该磁网络,分析了转子尺寸参数对电机空载电磁性能以及气隙磁密波形的影响,为高密度PMSM初步设计提供了一种有效快速的分析手段。
Based on MATLAB/Simulink a new parameter varying equivalent magnet network method was presented for a double-layer high density IPMSM. It took full consideration of leakage flux of rotor and automatically adjusted the magnetic permeability of each part through a parameter varying segment. Core saturation was taken into account so that the calculation accuracy of parameter varying equivalent magnet network method was greatly promoted.With this network method,the effects of rotor parameters to motor no-load electromagnetic performance and the air gap flux density waveform were analyzed. A fast and efficient way for original design of the high density IPMSM was proposed by the equivalent magnetic network method.
