要約
(EN) A 10-pole, 12-slot permanent magnet synchronous motor (100) is equipped with a plurality of teeth, wherein a first tooth (1bU1) positioned on the near side in the direction of rotation of a rotor 2, among two adjacent teeth around which coils (6U1, 6U2) of the same phase are adjacently wound, is formed in a manner such that the rotational direction width of a winding (1b1) thereof is narrower thanthe rotational direction width of a winding (1b1) of a second tooth (1bU2) that is positioned on the far side in the direction of rotation of the rotor 2. This configuration makes it possible to shorten the circumference of the coil (6U1) wound around the first tooth (1bU1), while suppressing an increase in iron loss of the winding (1b1) of the first tooth (1bU1).
(ZH) 一种10极12槽的永久磁铁同步电动机(100),具备多个齿,在相邻地卷绕有同相的线圈(6U1、6U2)的邻接的两个齿中,配置于转子(2)的旋转方向的跟前侧的第一齿(1bU1)的绕组部(1b1)的旋转方向宽度形成为比配置于转子(2)的旋转方向的里侧的第二齿(1bU2)的绕组部(1b1)的旋转方向宽度窄。通过该结构,能够在抑制第一齿(1bU1)的绕组部(1b1)中的铁损增加的同时,缩短卷绕于第一齿(1bU1)的线圈(6U1)的周长。
