Abstract:
A motor includes a support frame, a stator, a bearing member, and a rotor. The support frame includes first and second tubular parts, and a vent hole. The second tubular part is disposed radially outside the first tubular part. The vent hole, extending axially, is provided between the first and second tubular parts. The stator is disposed radially outside the second tubular part, and supported by the second tubular part. The bearing member is disposed inside and supported by the first tubular part. The rotor includes a rotor frame, a shaft, and a permanent magnet. The rotor frame is disposed on a first side with respect to the support frame in the axial direction. The shaft is fixed to the rotor frame. The shaft is attached rotatably to the support frame through the bearing member. The permanent magnet is disposed radially outside the stator, and supported by the rotor frame.
