Abstract
A method of controlling a motor connected to an unbalanced load in accordance with an embodiment of the present application includes operating the motor for a predetermined period of time with a first performance parameter held constant, monitoring a signal related to a second performance parameter, monitoring electrical rotation within the motor and providing an electrical rotation signal indicative of the electrical rotation angle, sampling the signal related to the second performance parameter at a predetermined angle of electrical rotation, arranging samples provided in the sampling step in predetermined order and generating a mechanical rotation signal representing the mechanical rotation angle of a rotor of the motor based on the arrangement of samples. The mechanical rotation signal is used to control at least one of the first and second performance parameters of the motor.
