Abstract
A method of controlling the commutation of a brushless direct current motor includes providing sensors which provide a variable output dependent on rotational angle or the relative position of the stator and rotor of the motor. Output from the sensors is sampled at a time between a past commutation event and the next commutation event to be implemented. An angular position between the rotor and stator is determined at the time. The time of the next commutation event is determined based on the next commutation angle, motor speed, and the determined angular position.
