Abstract: In order to keep the permanent magnet motor running, the magnetic field produced by the windings should shift position, as the rotor moves to catch up with the stator field. Rotor position is sensed using Hall effects sensors. With these sensors 6 different commutation are possible every 15°. Hence, this paper presents a model procedure for these 6 points. The aim of this paper is presented a magnetic model of surface mounted permanent magnet machine for different rotor positions.This paper is presented a PM machine with double layer concentrated winding with 8 poles and 12 slots. The FEM analysis is used for validation of models.
