Comparative Study of Two Different PMSG with Different Slot Pole Combination Having Non-Overlapping Winding Configuration

This paper presents a comparison of two different PM machiness having different slot-pole combinations with non-overlapping winding configuration. The two PM machines have been simulated in 2D FEM based software package with same nominal ratings and main dimensions but different winding configurations. The first machine with 20 pole, 24 slot has already been designed and developed in the laboratory. This has been compared with another PM machine having 28 pole, 24 slot. Various important parameters and performance indices have been compared in detail and presented. The merits and demerits of both the PM machines have been highlighted.
