Abstract

In a permanent magnet-embedded, concentrated winding motor, when a plurality of stator teeth (2a, 2b, 2c, . . . ) are divided into for example three groups (2, 3, 4) as a plurality of adjacent statorteeth having coils (6) wound around that are provided with voltage in phase are set as one group, coils are wound in opposite directions around adjacent stator teeth (2a, 2b, 2c) in the same group (2), while the relation between the angle h of a slot opening between adjacent stator teeth (2a, 2b) in the same group and the angle h of a slot opening formed between adjacent stator teeth (2a, 3c) belonging to different groups satisfies h<H<=3h.
一种电动机,具有定子(7)和转子(8),定子(7)由定子铁心(1)和绕组(6)构成,定子铁心(1)由多个定子齿部(2a~4c)及连接多个定子齿部(2a~4c)的定子轭铁(5)构成,绕组(6)分别绕卷于多个定子齿部(2a~4c)上,转子(8)由转子铁芯(9)和埋入转子铁芯(9)的多个永久磁铁(10)构成,具有多个组(2、3、4),这些组由绕卷有可施加同相电压的绕组(6)的邻接的多个定子齿部(2a~2c、3a~3c、4a~4c)构成,在同一组(2、3、4)内邻接的多个定子齿部(2a~2c、3a~3c、4a~4c)的绕组相互反向绕卷,对邻接的多个组(2、3、4)分别施加不同相的电压,同一组中相邻的定子齿部之间的切槽的大小不同于与相邻的、属于另一组的齿部之间的切槽。
