ABSTRACT:
A motor controller includes an input terminal (22), a frequency selective network, a first controller, and a second controller. The input terminal is adapted to be coupled to a drive phase of a motor (16) for receiving a signal (24). The frequency selective network (18) has an input coupled to the input terminal (22) and an output for providing a first signal representative of the back EMF signal within a frequency range corresponding to a predetermined harmonic frequency above a primary frequency thereof. The first controller (20) has an input coupled to the output of the frequency selective network (18) and an output for providing a second signal representative of a position or a velocity of a rotor of the motor (16). The second controller (10) has an input coupled to the output of the first controller (20) and an output for providing a third signal. The third signal indicates how the motor (16) is to be driven.
