ELECTRIC MOTOR

WIPO Patent Application WO/2021/200476

A1

[Problem] To provide an electric motor that makes it possible to reduce the size in the direction of the axis of rotation and suppress the deformation of a bearing and a bearing housing due to deformation of a resin outer shell. [Solution] One embodiment of this electric motor comprises a columnar rotor, a shaft arranged along the axis of rotation of the rotor, a cylindrical stator core arranged on the outer circumferential side of the rotor, a resin outer shell covering the stator core, a bearing rotatably supporting the shaft, and a bearing housing in which the bearing is accommodated. The resin outer shell has an annular section integrated with the stator core and an end face connected to the end of the annular section and extending in the inner circumferential direction from the annular section. The end face has a connection section connected to the bearing housing. The bearing housing has a cylindrical section and a flange section extending on the outer circumferential side in the radial direction from one end of the cylindrical section. The outer circumferential edge of the flange section is fixed to the connection section of the resin outer shell.
