摘要
航天用内置式永磁同步电机采用最大转矩/电流比控制方式,充分利用其磁阻转矩和高凸极率的特点实现大的弱磁扩速和最大转矩比。同时内置式永磁同步电机的转子外无护套等保护措施,转子结构的设计显得很重要。本文对一台20 k W的内置式永磁同步电机电磁参数、转子结构进行了设计,并利用有限元法对其进行了仿真分析。仿真分析的结果证实了该电机设计的正确性。
Interior permanent magnet synchronous motor for aerospace adopts the maximum torque current ratio control method,and takes advantage of the characteristics of reluctance torque and high salient rate to achieve high flux-weakening speed and the maximum torque ratio. At the same time,there is no sleeve protection outside the rotor,so the design of the rotor structure is important. The electromagnetic parameters and rotor structure of a 20 k W internal permanent magnet synchronous motor are designed in this paper,the simulation analysis is carried by the finite element method. The results of simulation analysis confirm the correctness of the design of the motor.
