SYSTEM AND METHOD FOR DETERMINING POLE SHIFT

摘要

A system includes a first proximity sensor and a controller. The first proximity sensor is disposed in a first location of a stator and configured to transmit a first signal representative of a first distance between the first proximity sensor and a plurality of rotor poles. The controller is communicatively coupled to the first proximity sensor. The controller is configured to derive a first plurality of instantaneous airgaps based on the first signal and to determine a difference between a first instantaneous airgap of the first plurality of airgaps and a second instantaneous airgap of the first plurality of airgaps. The first plurality of instantaneous airgaps includes a first plurality of measurements of gaps between the stator and the plurality of rotor poles when the rotor is rotating.
