Computation of the voltage-driven flux-MMF diagram for saturated PM brushless motors [PDF]

, 2005
The flux-MMF diagram or "energy conversion loop" is a powerful tool for computing the average torque of saturated permanent-magnet brushless motors, especially when the assumptions underlying classical dq theory are violated, as they often are in modern ...
