Abstract :
The research proposes a solution for the sensorless control of Surface Mounted PM motors at zero speed. A creative strategy that involves minor change in the rotor is presented. The proposed FEA serves to evaluate the effectiveness of the strategy quickly and accurately down to very low speed.
