Abstract
First and second stator circuitry for respective use with first and second stators in a multi-stator motor are configured so that the first stator circuitry is substantially unaffected by a failure of the second stator circuitry to energize a second winding in the second stator. To that end, the motor includes a rotor that rotates through a plurality of rotational positions, the first stator having the first stator circuitry and a first winding, and the second stator having the second stator circuitry and a second winding. The first stator circuitry energizes the first winding in response to the rotational position of the rotor. In a similar manner, the second stator circuitry energizes the second winding in response to the rotational position of the rotor.
