  • Electric machines having a radially embedded permanent magnet rotor and methods thereof
    Patent number: 11984763
    Abstract: A permanent magnet rotor core includes a plurality of rotor poles circumferentially-spaced about a central axis and including a first rotor pole and an adjacent second rotor pole that each include an outer wall, and wherein the rotor core includes a rotor diameter. The rotor core also includes a plurality of radial apertures alternately-spaced with the plurality of rotor poles. The rotor core also includes a first protrusion extending from the first rotor pole into a first radial aperture of the plurality of radial apertures positioned between the first rotor pole and the second rotor pole. The rotor core further includes a second protrusion extending from the second rotor pole into the first radial aperture such that a circumferential opening is defined between the first protrusion and the second protrusion. The opening extends a first length of between approximately 0.052% and approximately 0.058% of the rotor diameter.

  • Method and apparatus for correcting motor imbalance
    Publication number: 20030021692
    Abstract: A blower assembly includes a motor including a shaft extending therefrom and a blower wheel including a hub. The blower wheel is attached to the motor shaft. A first slot extends through the hub and a second slot extends through the hub. The first slot is angularly displaced around the hub about 180 ° from the second slot.
