Patent abstract
A multi phase motor includes a switching array for interconnecting a power source to each phase. A current sensor senses current supplied from the power source via the switching array to the winding and a controller generates offset PWM signals for controlling the switching array to supply power to each of the phases of the winding. The offset timing allows the individual phase currents to be determined from a single current sensor.
