Title:
シャフトの低速回転制御のためのスラスト能動型磁気軸受
Document Type and Number:
Japanese Patent JP6781345
Kind Code:
B2
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.
