分析了轴向分段式外永磁转子高速爪极电机的特殊结构及运行原理。由于研究对象的磁路具有非对称性,为了得到更加准确的仿真结果,在Maxwell 3D平台中按照样机的实际参数,建立了研究对象的3D模型;为实现驱动电机的目标,并考虑到电机在运行时,电机本体与控制电路产生的场路耦合效应,在Simplorer中搭建了电机的控制系统模型,对电机进行Maxwell&Simplorer联合仿真并采用了无位置传感器的控制策略,控制电路包括逆变电路和换相电路以及双闭环的控制电路。从仿真结果可知,该控制系统模型可以使电机稳定运行,并且有良好的起动性能。本文的研究工作对轴向分段式外永磁转子高速爪极电机控制系统的设计与优化,及联合仿真的研究工作,具有一定的参考价值。

The special structure and operating principle of the high speed claw pole motor with axially segmented outer rotor was presented in this paper. In order to obtain an accurate simulate result, a three dimension（3D） finite element model（FEM） that was consistent with actual parameters was built in Maxwell 3D due to its asymmetry of the magnetic circuit. Considering the coupling effect of the motor finite element model and control circuit model in calculation, a control system model adopting sensorless and double-loop control strategy was done in a co-simulation platform using MaxwellSimplorer software. Inverter circuit and commutation circuit were included in the control circuit to achieve the target of driving motor. From the simulation result, the motor ran stably and had a good starting performance. Research in this paper has reference value for control system design and optimization of high speed claw pole motor with axially segmented outer rotor in some degree.
