Abstract:
Methods and systems for operating a motor having a rotor rotatable relative to a stator include commutating the motor to cause the rotor to rotate to a known position. While the rotor is at the known position, a position of an encoder magnet configured to rotate with the rotor is measured. Subsequent commutation of the motor is adjusted to take into account a difference between the known position of the rotor and the measured position of the encoder magnet.
