1. A rotatable stator sensor device comprising:
a stator support plate configured to support a steel stator having multiple teeth;
a rotary table which is electrically isolated from the stator support plate;
at least two sensors on the rotary table, the at least two sensors located within an inner circumference of the steel stator, each of the at least two sensors including two sensor legs, wherein a distance between the two sensor legs corresponds to a distance between two of the multiple teeth of the steel stator; and
a sensor rotation control module configured to rotate the at least two sensors between a first position aligned with a first set of the multiple teeth of the steel stator, and a second position aligned with a second set of the multiple teeth of the steel stator, wherein the first set of the multiple teeth is different than the second set of the multiple teeth.
