A method and apparatus for commutating a brushless direct current motor (10) having a set of stator windings (14) and a rotor (16) movable relative to the set of stator windings includes sensing a position of the rotor relative to the set of stator windings with a position sensor and providing a sensor signal indicative of the position. The position signal is monitored with a commutation state machine (40) and/or a hysteresis generator The stator windings are commutated as a function of the commutation state machine and/or the hysteresis generator and a position of the rotor. <IMAGE> |
