Claim 11:
12. A motor controller operable to control a motor, comprising:
an angular position estimator circuitry coupled to a first terminal, configured to receive a measured current of the motor, and configured to determine an estimated angular position of the motor based on the measured current;
an angular velocity estimator circuitry coupled to the first terminal, configured to receive the measured current of the motor, and configured to determine an estimated angular velocity of the motor based on the measured current; and
a multiphase current generator coupled to a motor drive terminal, selectively coupled to the angular position estimator circuitry, configured to receive either the estimated angular position or a forced angular position of the motor, configured to receive a motor control signal that is based on either a calculated target current or a forced target current, and configured to generate a motor drive signal based on the motor control signal and either the estimated angular position or the forced angular position,
wherein the motor drive signal is based on the calculated target current and the estimated angular position while a target angular velocity is greater than a threshold angular velocity, and wherein the motor drive signal is based on the forced target current and the forced angular position while the target angular velocity is less than the threshold angular velocity.
