Abstract
This paper proposes a new non-overlapped six-phase Fractional Slot Concentrated Winding (FSCW) layout for a Permanent Magnet (PM) synchronous wind generator with an outer rotor and surface mounted magnets. The proposed FSCW layout is originally an asymmetrical nine phase winding where the nine phases are connected with a special connection as to provide an equivalent stator winding with six terminals only. The proposed winding successfully offers a high torque and voltage qualities with a low cogging torque. Besides, the stator and rotor core losses are reduced when compared with a three-phase counterpart. Finally, the high phase order of the proposed generator provides a better fault tolerant generator design. A 100kW PM generator with an outer rotor based on the proposed winding layout is designed and simulated using 2D Finite Element Analysis (FEA).
