  • Publication number: 20230155444
    Abstract: [Object] To provide an electric motor that can be downsized in a rotation axis direction and can also suppress the deformation of a bearing and a bearing house portion along with the deformation of a resin shell. [Solving Means] An electric motor according to an aspect of the present invention includes: a columnar rotor; a shaft disposed along a rotation axis of the rotor; a cylindrical stator core disposed on an outer circumferential side of the rotor; a resin shell that covers the stator core; a bearing that rotatably supports the shaft; and a bearing house portion that stores the bearing. The resin shell includes an annular portion integral with the stator core, and an end surface portion connected to an end portion of the annular portion and expanding from the annular portion to an inner circumferential side. The end surface portion includes a connection portion to be connected to the bearing house portion.

  • Publication number: 20230155443
    Abstract: [Object] To provide a permanent magnet electric motor that can be downsized in a rotation axis direction and can also suppress a leakage flux. [Solving Means] The permanent magnet electric motor includes: a columnar rotor including a permanent magnet portion annularly disposed; a shaft disposed along a rotation axis of the rotor; a cylindrical stator core disposed on an outer circumferential side of the rotor; a main body including a shell integrally formed with the stator core; a bracket attached to one end side of the main body; and a bearing that rotatably supports the shaft. The bracket includes a bearing house portion that stores the bearing, and a non-magnetic portion that is connected to the bearing house portion. The bearing house portion is disposed on an inner diameter side relative to the permanent magnet portion as viewed from an axis direction of the rotation axis, and an edge portion of the bearing house portion on an outer diameter side is covered with the non-magnetic portion.
