Abstract: A circuit for controlling a motor that includes control circuitry configured to determine whether a commutation event has occurred for a first sector of a plurality of sectors of a cycle for the motor based on a first selected phase current signal and a second selected phase current signal. In response to a determination that the commutation event has occurred for the first sector, the control circuitry is configured to determine that the motor is operating in a second sector of the plurality of sectors of the cycle for the motor. The control circuitry is further configured to determine a second angle of stator voltage vector for the motor based on the determination that the motor is operating in the second sector and generate the control signal based on the second angle of stator voltage vector for the motor.

Abstract: A circuit for controlling a motor that includes control circuitry configured to generate, for a phase of the motor, a switching signal indicating to couple the phase to a first terminal of a supply for an entire portion of each switching cycle of a first plurality of switching cycles corresponding to a first range of electrical angles for the rotor and to couple the phase to a second terminal of the supply for a portion of each switching cycle of a second plurality of switching cycles corresponding to a second range of electrical angles for the rotor. The control circuitry is further configured to control the motor based on the switching signal.
