Abstract: A symmetrical cooling system for an electric rotor machine that includes a passageway that is positioned between portions of the stator, and which provides a pathway for a cooling medium. Stator ducts positioned within the stator, or portions thereof, are in fluid communication with the passageway. Cooling medium may flow through the suitor ducts from the passageway to ends of the stator so that the cooling medium only travels along a portion of the overall axial length of the stator. The symmetrical cooling system also includes an air gap dial is positioned between the stator and the rotor, and which receives cooling medium from the passageway at a midsection of the air gap. Cooling medium received at the midsection of the air gap may then flow towards either first or second ends of the stator.

Abstract: A permanent magnet bearing supports part of thrust loads of a vertical shaft induction motor, or the thrust loads of other types of rotation machinery regardless of shaft rotational axis orientation, in parallel with a lubricated mechanical bearing. The permanent magnet has a stationary magnet portion coupled to a bearing bracket and a rotating portion adapted for coupling to a rotor shaft. The permanent magnet bearing exerts a directional magnetic force that generates a preload support force on the rotor shaft that is selectively varied by varying air gap between the stationary and rotating magnet portions. Air gap between the magnet portions is varied with an air gap adjustment mechanism. The gap adjustment mechanism may be coupled to a control system that in some embodiments causes the permanent magnet bearing to vary the air gap based on external load applied on the motor.
