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.

Abstract: A rotor assembly for an electrodynamic machine is provided. The rotor assembly comprises a lamination section and an end connector. The lamination section comprises rotor lamination sheets formed to define an annular array of axial cooling ducts mechanically supported by a plurality of radial and arched structural members that define an array of arched or angled supports to readily pass a magnetic flux via an optimal flux path. The lamination section further comprises rotor slots, with rotor conductor bars being disposed in the rotor slots. The end connector is supported by the rotor conductor bars. An axial space is formed in the lamination section by the annular array of axial cooling ducts for guiding a cooling fluid flow in an axial direction through the rotor assembly.

Abstract: Permanent magnet bearings are incorporated into rotating equipment, such as induction machines, in addition to active magnetic or lubricated primary shaft support bearings. The passive magnetic bearings incorporate permanent magnets that generate directionally oriented magnetic fields of selective intensity. The magnetic field directions are aligned with a desired shaft support bearing preload direction and intensity, for example to exert axial thrust or radial preloads on the support bearings. A plurality of magnetic bearings may be oriented in opposed relationship with neutral or offsetting resultant forces. The passive magnetic force preload may be utilized to offset rotor vertical weight during induction startup or stopping cycles. Passive magnetic force preload may be applied to lubricated bearings to assure their operational stability. The passive magnetic bearings can also absorb radial or axial thrust forces imparted on the rotor shaft during induction machine operation, that may reduce machine operational noise, and energy consumption.
