三相无刷直流电动机分数槽集中绕组槽极数组合规律研究(连载之一)

Investigation on Slot/Pole Number Combinations for 3-phase BLDCM with Concentrated Windings

分数槽集中绕组在无刷直流电动机应用日渐广泛。研究无刷直流电动机分数槽绕组的相数m、槽数Z、极对数p等设计参数之间的相互关系和约束条件,着重分析三相无刷直流电动机分数槽集中绕组槽极数Z/p组合规律,给出符合分数槽集中绕组条件的Z/p组合选择表。过去关于分数槽集中绕组文献多只提及表示为Z0=2、p0±1和Z0=2、p0±2的组合,文中给出更多的槽极数组合;同时引入了单元电机和虚拟电机概念,讨论了分数槽绕组和整数槽绕组的绕组分布系数对应关系等问题,可供设计者参考。

Using BLDCM with concentrated windings recently is growing. The aim of this paper is to study the rule of slot/pole number combinations for BLDCM with concentrated windings, and to summarize a table of feasible slot/pole number combinations. This paper discusses as well as cell motor, dummy motor, and winding factor relation between concentrated windings and distributed windings.
