Claim 15:
16. The electric powertrain of claim 9, wherein the shunt angle transition occurs while hardware devices embedded within the VFM change positions to corresponding impart a change of direction in magnetic flux, and the controller includes a torque control loop having a torque command calculation block configured to determine a commanded torque from the commanded shunt angle, a commanded d-axis current, and a commanded q-axis current, and a torque estimate block configured to determine an estimated torque from the measured shunt angle, the commanded d-axis current, and the commanded q-axis current, wherein the commanded d-axis current and the commanded q-axis current are the adjusted Id term and the adjusted Iq term, respectively.
