    • A rotating electric machine for a compressor includes a case, a plurality of teeth, coils and insulating films. The teeth are circumferentially arranged around a predetermined axis forming a center of the teeth. Each tooth has a first end disposed radially at an opposite side thereof from the predetermined axis. The a back yoke has a circular outer periphery, and a cylindrical inner periphery connecting the first ends of the teeth. The outer periphery has a plurality of concave parts opening radially inwardly toward the teeth at positions overlapping with the teeth as viewed radially. A minimum distance measured from an exposure surface of each tooth to the concave part overlapping therewith is smaller than a radial width of the back yoke at a portion where the concave parts are not provided. The exposure surfaces extend radially inwardly of the inner periphery.
    • 用于压缩机的旋转电机包括壳体,多个齿,线圈和绝缘膜。 齿围绕形成齿的中心的预定轴线周向布置。 每个齿具有径向设置在与预定轴线相对的一侧的第一端。 背轭具有圆形的外周边和连接齿的第一端的圆柱形内周。 外周边具有径向向内朝着与牙齿重叠的位置的齿向径向向内开放的多个凹部。 从每个齿的暴露表面到与其重叠的凹部测量的最小距离小于在未设置凹部的部分处的后轭的径向宽度。 曝光表面径向向内延伸。

    • A first non-magnetic portion, a second non-magnetic portion, and a third non-magnetic portion are arranged around an axis, from an end toward the center of a permanent magnet burying hole. A fourth non-magnetic portion is further provided between the second non-magnetic portion and the third non-magnetic portion. Angles around the axis are determined as follows with reference to a position between permanent magnet burying holes. The position between the first non-magnetic portion and the second non-magnetic portion is expressed by a first angle. The position between the third non-magnetic portion and the fourth non-magnetic portion is expressed by a second angle, and the second angle is twice the first angle. The end of the third non-magnetic portion located closer to the pole center is expressed by a third angle. The first angle and the third angle are values obtained by dividing 360 degrees respectively by a value that is seven times, and a value that is three times, the number of the permanent magnet burying holes.
    • 第一非磁性部分,第二非磁性部分和第三非磁性部分围绕永磁体埋入孔的端部至中心的轴线布置。 第四非磁性部分还设置在第二非磁性部分和第三非磁性部分之间。 参照永磁体埋入孔之间的位置,如下确定轴周围的角度。 第一非磁性部分和第二非磁性部分之间的位置由第一角度表示。 第三非磁性部分和第四非磁性部分之间的位置用第二角度表示,第二角度是第一角度的两倍。 靠近极点的第三非磁性部分的端部由第三角度表示。 第一角度和第三角度是通过将360度分别除以永久磁铁掩埋孔的数量的七倍的值和三倍的值而获得的值。
