ABSTRACT:
System, method, and apparatus for commutating and controlling a multi-phase motor using one output rotor sensor and circuitry that measures time between rotor pole-to-pole transitions is disclosed. The exemplary system, method, and apparatus may utilize the polarity of the single-output rotor sensor and the measured time between the polarity transitions detected by the single-output rotor sensor.
