Abstract :
This paper describes an investigation into the cogging torque in 4-pole interior-magnet brushless machines, having either 6 slots and a short-pitched non-overlapping winding (i.e. concentrated coils), or 12 slots and a full-pitched overlapping winding, the inner and outer diameters and the slot openings being identical.
