摘要/Abstract

摘要： 通过有限元比较分析了不同分布式绕组结构对表贴式永磁电机性能的影响。依据对称三相分布式绕组的构成原则,总结了采用该绕组的电机在极槽配合方面需要满足的约束条件。在满足极槽配合约束的电机中选择了4台电机作为研究对象,并对具有不同分布式绕组结构的电机进行了电磁性能比较,包括气隙磁场、空载性能、负载性能、效率性能以及其它相关性能。根据理论与有限元分析结果总结出不同分布式绕组所具有的优缺点。在实际应用中,结合需求来选择最为合适的绕组结构。

关键词: 绕组结构, 分布式绕组, 极槽配合, 转矩脉动, 效率

Abstract: The influence of distributed winding topology on the performance of surface-mounted permanent magnet (SPM) machines were studied comparatively by finite element (FE) analysis. The constraints of slot and pole number combinations which can be used in SPM machines were summarized based on the construction principle of symmetrical 3-phase distributed windings. Four prototypes which satisfy the constrains of slot and pole number combinations were chosen and the electromagnetic performance of these machines with different distributed winding topologies was compared, including air-gap field, open-circuit characteristics, on-load characteristics, efficiency characteristics and so forth.The advantages and disadvantages of different distributed windings were summarized base on theoretical and FE analysis. It could be concluded that the most suitable winding topology should be selected according to the requirements of specific application.

Key words: winding topology, distributed winding, slot and pole number combination, torque ripple, efficiency
