摘要
本文针对航空领域电推进系统,以高效高性能为目的对电推进电机进行研究。首先建立了三种转子结构电机模型,在满足电机运行指标前提下,利用解析计算和有限元软件,从电,热和力三个方面对电机性能进行综合对比,从而得到了最优转子结构。之后根据航空领域电机的特殊需求特点,将模块化定子概念引入到该电机设计中。通过比较定子模块化前后一些电机性能指标变化,证明了模块化定子电机具有质量更低和效率更高的优点,进一步说明了模块化定子在航空电推进领域的可行性。本文对航空领域电推进电机进一步深入研究和电机轻量化设计具有参考价值。
Aiming at the electric propulsion system in aviation application,this paper studied the electric propulsion motor with high efficiency and high performance.First,three models with different rotor structure were established.On the premise of satisfying the motor’s work indexes,analytical calculation and FEM(Finite element simulation)software were used to comprehensively compare the motor’s performance from three aspects of electricity,thermal and structural,so as to obtain the optimal rotor structure.Then according to the special requirements of aviation motor,the modular stator concept was introduced int this paper.Through the analysis and comparison of some motor performance before and after the modularization of stator,the advantages of motor with the modular stator with lower quality and higher efficiency were obtained,which further illustrated the feasibility of the modular stator in the field of aeronautic electric propulsion application.This paper has reference value for further research and lightweight design of electric propulsion motor in aviation application.
