  • Permanent magnet machine
    Patent number: 6946766
    Abstract: An interior permanent magnet machine including a rotor stack defining at least two adjacent magnet retention slots and a plurality of permanent magnets positioned within the interior of the rotor, wherein the radial thickness of the rotor that is above a given magnet retention slot transitions from a first radial thickness to a bridge region having a second radial thickness that is less than the first radial thickness. The bridge region is positioned between the two magnet retention slots and the transition to the bridge region occurs within an area falling within a defined angular expanse.
    Type: Grant
    Filed: August 28, 2002
    Date of Patent: September 20, 2005
    Assignee: Emerson Electric Co.
    Inventors: Horst E. Gary, Richard E. Hartsfield, Jr., Mark E. Carrier
  • Interior permanent magnet machine with reduced magnet chattering
    Patent number: 6891298
    Abstract: A rotor for an interior permanent magnet machine that tends to reduce magnet chattering that includes a rotor stack defining at least one magnet retention slot and a permanent magnet positioned within the magnet retention slot, where the magnet retention slot is formed such that movement of the permanent magnet towards at least one end of the slot will tend to cause the magnet to become wedged within the slot.
