Abstract
A motor includes a stator having a stator core, a first frame and a second frame, which are arranged on two axial sides of the stator core, a coupling member, which couples the first and second frames at a radially outer side of the stator while applying a holding load to the first and second frames in the axial direction, and a rotor, which is arranged at a radially inner side of the stator. The stator core includes a held portion that projects toward a radially outer side from a main circumferential portion of the stator core. The first and second frames hold, in between, at least the held portion of the stator core in the axial direction.
Claims25
A motor comprising:
- a stator including a stator core, a plurality of teeth extending toward a radially inner side from a main circumferential portion of the stator core, and an armature winding attached to the teeth, wherein the stator core includes a held portion that projects toward a radially outer side from the main circumferential portion;
- a first frame and a second frame respectively arranged on two axial sides of the stator core to hold, in between, at least the held portion of the stator core in the axial direction, wherein the first frame and the second frame are formed so that the main circumferential portion of the stator core is exposed to the exterior from between the first frame and the second frame;
- a coupling member that couples the first and second frames at the radially outer side of the stator while applying a holding load to the first and second frames in the axial direction;
- and
- a rotor rotatably supported by the first and second frames and arranged at the radially inner side of the stator.
