System and Method for Motor Control Using Position Sensors

An embodiment method for motor control includes monitoring a plurality of position sensors coupled to a revolving motor. The monitoring includes measuring transition times of respective output patterns produced by the position sensors, the respective output patterns each including at least one transition time that repeats in accordance with each revolution of the motor. The method further includes determining a first revolution period in accordance with the measured transition times. The method also includes determining an elapsed fraction of the first revolution period that has elapsed since a start time of the first revolution period.
