ABSTRACT:
A motor control is provided with both open loop and closed loop controllers. The open loop and closed loop controllers provide commutation signals back to gate drives for an inverter, wherein the commutation signals utilize sinusoidal signals in open loop control, and utilize six step commutation in closed loop control.
