摘　　要：即使电机的设置不同,也可能会有几乎一样的动态特性或者只是工作特性上稍有不同;所以无轴承电机的复杂性就为其结构设计提供了多个自由空间。但是,机械安装会对功率逆变器的拓朴结构和伏安特性造成很大的冲击,并且会在很大程度上影响系统的成本。主要讨论永磁体砺磁的无轴承薄片电机技术设计研究,在分析力与力矩模型的基础上,研究了电机设计的相关性能指标,并提出了一种基于性能指标的系统评测方法。The complexity of a bearingless motor offers a multitude of freedom in constructive design because different motor setups may even have nearly the same dynamic behavior and may differ only slightly in some operation characteristic.However,the mechanical setup often has a very strong impact on the power inverter topology and the volt-ampere requirements and thus,it affects the system costs significantly.The technical design of bearingless thin section motor with permanent magnet is mainly discussed.Based on the analysis of force and moment model,the performance indexes of motor design are studied,and a system evaluation method based on performance indexes is proposed.
