  • Patent number: 10461618
    Abstract: A PMDC motor has a housing, a stator magnet disposed in an interior of the housing, and a rotor core disposed within the stator magnet. A ratio of an outer diameter of the rotor core to the outer diameter of the housing is from 0.60 to 0.67. The noise of the motor during operation is reduced by increasing the thickness of the stator magnet, reducing the outer diameter of the rotor core, reducing the air gap between the magnet and the rotor core and reducing the rotational inertia of the rotor core. The motor is particularly suited for use in vehicle HVAC systems where low noise is an important requirement.

    Abstract: A single phase permanent magnet motor includes a stator. The stator includes a stator core and windings. The stator core includes a ring portion, tooth bodies extending radially from the ring portion, and a pole shoe extending from a distal end to two circumferential sides of each tooth body. Each pole shoe defines a positioning slot. A center of each positioning slot is offset from a center of symmetry of one adjacent tooth body so that a torque fluctuation of an output torque of the single phase permanent magnet motor during operation is less than 50%. As a result, the motor vibration and noise are small.

  • Patent number: 10447107
    Abstract: A cover for a motor drive is provided. The cover includes an opening (often at the bottom of the cover) to allow air to pass to an air inlet of the motor drive and an opening (often near the top of the cover) to allow air from an air outlet of the motor drive to exit the cover. A hood provides rain protection for the drive and a separator (such as a baffle) within the enclosure prevents air flowing within the enclosure from the air outlet to the air inlet of the drive. The hood and/or the separator are shaped to direct air from the air outlet away from the enclosure in order to substantially reduce the re-circulation of air from the air outlet to the air inlet of the drive.
