以一种12/22极磁场调制型外转子磁通切换(outer-rotor flux-switching permanent magnet, OR-FSPM)电机为例,基于磁场调制原理对其进行分析.通过分析气隙磁密谐波,确定绕组的连接方式.此外,考虑到永磁材料易受温度影响,提出一种能实时交换数据的电-热双向耦合方法.通过推导永磁体不同温度下的Bi-H 曲线,来获得相应的整个温度区间的B-H曲线,从而进一步采用电-热双向耦合方法对电机进行热分析,并与传统的热分析结果比较.然后,将双向耦合分析得到的实际性能反馈到初始设计中,在设计中考虑温度影响,调整电机参数,提升电机实际性能.最后,制造样机并实验,理论分析和实验结果验证所提方法的有效性.“,”A 12/22 magnetic field modulated outer-rotor flux-switching permanent magnet (OR-FSPM) machine was analyzed based on the magnetic field modulation principle. The winding configuration was determined by analyzing the harmonic components in the airgap. In addition, considering the influence of the temperature on PM materials, an electrical-thermal bi-directional coupling method was proposed, which can realize exchanging data. By deducing the Bi-H curves of the PM at different temperature, the corresponding B-H curves in whole temperature range were fitted and derived. Based on the obtained PM B-H curves, the electrical-thermal bi-directional coupling analysis was conducted. Then, according to the obtained performances, a feedback design was implemented on key parameters adjustment to improve the real performance, which took the influence of the temperature into consideration. Finally, a prototype machine was manufactured, and the theoretical analysis and studied results verified the effectiveness of the proposed method.
