Provided are: an electric motor which makes it possible to suppress the reduction of output while having a stator of a desired length in the axial direction and in which the assembly workload and fabrication cost can be reduced; a vehicle power device equipped with this electric motor; a generator; and a generator-attached wheel bearing equipped with this generator. A stator core (18a) is provided with: a circular ring component (21) formed by laminating a plurality of circular ring sheet-shaped bodies (20) each having a plurality of radial first tooth sheet portions (20a) and a circular ring sheet portion (20b) to which the base end portions of the first tooth sheet portions (20a) are connected; and a plurality of non-circular ring components (31) each formed by laminating a plurality of partial sheet-shaped bodies (22) including two second tooth sheet portions (22a), (22a) adjacent to each other in the circumferential direction and a connecting sheet portion (22b) to which the base end portions of the second tooth sheet portions (22a), (22a) are connected. The plurality of non-circular ring components (31) are annularly disposed side by side in the circumferential direction with respect to the circular ring component (21) so that each of the first tooth sheet portions (20a) and each of the second tooth sheet portions (22a) become the same phase.

    提供一种电动机、具有该电动机的车辆用动力装置、发电机及带有该发电机的车轮用轴承,其中,可使定子为期望的轴向长度并抑制输出的降低,另外,可谋求组装工时和制作成本的降低。定子铁芯(18a)包括:圆环部件(21),在该圆环部件(21)中,叠置有多个圆环板状体(20),该圆环板状体(20)具有呈放射状设置的多个第1齿板部(20a)以及与这些第1齿板部(20a)的基端部分连接的圆环板部(20b);多个非圆环部件(31),在该多个非圆环部件中(31)叠置有多个部分板状体(22),该部分板状体(22)具有在圆周方向上相邻的至少两个第2齿板部(22a)以及连结这些第2齿板部(22a)、(22a)的基端部分的连结板部(22b)。以第1各齿板部(20a)和第2各齿板部(22a)为相同相位的方式,多个非圆环部件(31)相对于圆环部件(21)在圆周方向上排列配置成环状。
