摘　　要：针对U型磁障转子永磁辅助同步磁阻电机(PMA-SynRM),在定、转子设计方面进行研究。以设计的一台4极24槽小型PMA-SynRM为例,对比不同定子裂比、气隙长度下的电磁性能和转矩性能;提出U型磁障转子参数化设计模型及方法,研究U型磁障转子参数对PMA-SynRM交直轴电感差值、输出转矩、转矩脉动的影响。借助有限元分析法验证参数化设计分析合理性,发现利用参数化分析法对电机的电磁参数和转矩参数进行仿真分析时,转子的某一参数选取会出现最优值,可综合选取U型转子设计的最优方案,为同类型PMA-SynRM设计分析提供参考。For the U-magnetic barrier rotor,the research on permanent magnet-assisted synchronous reluctance motor(PMA-SynRM)is carried out in stator and rotor design.The 4-pole 24-slot small PMA-SynRM designed in this paper taken as an example,the electromagnetic performance and torque performance under different stator split ratios and air-gap lengths are compared;the parametric design model and method for the U-magnetic barrier rotor are proposed,and the effects of the parameters of the U-rotor on the alternating and straight axes of the inductance difference,output torque,and torque pulsation of the PMA-SynRM are studied.With the help of finite element analysis method to verify the reasonableness of parametric design analysis,it is found that when the electromagnetic and torque parameters of the motor are simulated and analyzed by using the parametric analysis method,the optimum value of a parameter selection of the rotor occurs,and the optimum solution for the design of the u-rotor can be selected comprehensively,which can provide reference for the design and analysis of the same type of PMA-SynRM.
