Claim 11:
12. A method comprising:
generating a control signal for controlling the motor based on a first angle of stator voltage vector for the motor, wherein the first angle of stator voltage vector is associated with a first sector of a plurality of sectors of a cycle for the motor;
identifying, from a first phase current signal indicating current flow at a first phase of the motor, a second phase current signal indicating current flow at a second phase of the motor, and a third phase current signal indicating current flow at a third phase of the motor, a first selected phase current signal indicating a current direction and a second selected phase current signal
indicating the current direction of the first selected phase current signal, wherein the current direction comprises a positive current direction indicating that phase current is greater than zero or a negative current direction indicating that phase current is less than zero;
determining whether a commutation event has occurred for the first sector based on the first selected phase current signal and the second selected phase current signal;
in response to determining that the commutation event has occurred for the first sector, determining that the motor is operating in a second sector of the plurality of sectors of the cycle for the motor;
determining a second angle of stator voltage vector for the motor based on the determination that the motor is operating in the second sector; and
generating the control signal based on the second angle of stator voltage vector for the motor.
