摘要： A method for driving a motor having a plurality of phases is provided. Initially, first, second, and third intervals for a pulse width modulation (PWM) period from first and second voltage commands are generated. The first and second voltage commands correspond to a voltage vector for the motor, and the voltage vector has an associated sector. A conversion formula is then determined for the first, second, third intervals based on the associated sector for the voltage vector. Using the conversion formula and the first, second, and third intervals, fourth, fifth, and sixth intervals are generated, and a set of PWM signals for the PWM period is generated from the fourth, fifth, and sixth intervals. The motor is then driven with the second set of PWM signals, and a current traversing the plurality of phases with a single shunt is measured.
