Motor and vehicle-mounted air conditioner using same

摘要

A motor includes a shaft, a rotor mounted to the shaft along an axial direction of the shat, a stator confronting an outer wall of the rotor via a space, a thrust plate, and a buffering plate having elastic force. The rotor and the stator are disposed such that a magnetic center of the rotor is away from a magnetic center of the stator by a given distance along the axial direction. The thrust plate is disposed in the axial direction and in a direction along which restoring force acts. The buffering plate is disposed oppositely to the shaft relative to the thrust plate and supports the thrust plate.

主权项

1. A motor comprising:
a motor housing having an axial end side that closes the motor housing; a shaft placed axially movable inside the motor housing for rotation and having a thrust end positioned on the axial end side of the motor housing; a rotor mounted securely to the shaft for rotation with the shaft; a stator secured radially adjacent to the rotor via a space inside the motor housing, wherein magnetic centers of the rotor and stator are axially offset such that a magnetic restoring force is generated to urge the shaft towards the axial end side of the motor housing; a thrust plate being disposed in the motor housing between the shaft and the axial end side of the motor housing; and an elastic buffering plate for elastically damping vibrations being held in the motor housing between the thrust plate and the axial end side of the motor housing.
