    Abstract: A thrust magnetic bearing integrated with an induction machine and methods for using the same for slow roll control of rotors and other rotating components is provided. The rotor can include a shaft and a thrust bearing disk. The thrust magnetic bearing can include thrust bearing stators positioned axially adjacent to the thrust bearing disk and they can be configured to apply axial magnetic forces to the thrust bearing disk. The induction machine can be configured to generate a rotating magnetic field that causes a torque to be applied to the thrust bearing disk in a predetermined rotational direction. In one aspect, the induction machine can include a radial stator positioned adjacent to a circumference of the thrust bearing disk and two or more circumferentially offset windings. In another aspect, the induction machine can position the two or more circumferentially offset windings on the thrust bearing stators.

  • Patent number: 10208760
    Abstract: A controller for a rotary machine includes a processor and a memory coupled to the processor. The memory is configured to store operating modes of the controller. The operating modes include a normal operating mode and a fault tolerant operating mode. The controller is configured to receive a signal from at least one sensor and determine an operating state of the rotary machine based on the signal. The controller is also configured to switch the operating modes based on the determined operating state of the rotary machine and regulate at least one electromagnetic bearing and at least one flow control device. The controller is further configured to adjust at least one of the at least one electromagnetic bearing and the at least one flow control device in the fault tolerant operating mode.
