  • Patent number: 9214840
    Abstract: A fan motor includes a motor having a shaft, a fan, and a fan fixing section for rigidly connecting the fan to the shaft. The fan has a first mounting face for the fan to be integrated with the motor. The fan fixing section has a fan mounting plate mounted to an end of the shaft and including a second mounting face in a radial direction, and an elastic plate having elastic force. The first mounting face is connected to the second mounting face via the elastic plate.
    Type: Grant

  • Patent number: 8890382
    Abstract: 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.

  • Patent number: 7834567
    Abstract: A motor drive device for alternately driving a plurality of motors includes a position detection signal processing circuit for processing position detection signals of the plurality of motors, a pre-drive circuit for generating an excitation switching signal of the motors, a plurality of power switching circuits for supplying an electric current to the motors in response to an output from the pre-drive circuit, and a motor switching circuit for instructing a switchover of driving the motors. The position detection signal processing circuit, in response to an input signal to the motor switching circuit, selects a position detection signal of a motor to be driven out of the position detection signals of the plurality of motors, and inputs a position detection processed signal to the pre-drive circuit for selecting one of the plurality of power switching circuits.
