本发明公开了种多相电励磁同步电机，包括由导磁材料构成的定子和转子且二者之间有气隙，定子上设有4*m*k*n个定子导磁齿，定子导磁齿上设有集中电枢绕组和集中励磁绕组；其中，每个集中电枢绕组套着相邻两个定子导磁齿，相邻集中电枢绕组共用个槽；每个集中励磁绕组套着相邻两定子个导磁齿，相邻两个集中励磁绕组共用或间隔个槽；转子导磁齿的个数为(2*m*k±1)n个；m为电机的相数，n为电机单元数，k为每个电机单元中任意相电枢绕组串联的集中电枢绕组对数。该电机具有无刷、转子结构简单、相反电势对称且近似正弦、转矩脉动小、定子励磁等特点；可用于城市轨道交通、电动汽车等需要宽调速范围场合。 The invention discloses a multiphase electro-magnetic synchronous motor which comprises a stator and a rotor. The stator and the rotor are made of magnetic conductive materials, an air gap is arranged between the stator and the rotor, 4*m*k*n stator magnetic conductive teeth are arranged on the stator, and centralized armature windings and centralized exciting windings are arranged on the stator magnetic conductive teeth. Each centralized armature winding is arranged on two corresponding adjacent stator magnetic conductive teeth in a sleeving mode, and the adjacent centralized armature windings share one groove. Each centralized exciting winding is arranged on two corresponding adjacent stator magnetic conducive teeth in a sle
