Comparisons of Concentrated and Distributed Winding PMSM in MV Power Generation
Paper i proceeding, 2018

This paper presents the design and comparison of an interior permanent magnet synchronous generator (IPMSG) with fractional-slot concentrated winding (FSCW) and distributed overlap winding used in medium voltage (MV) medium power generator. Analytical method is used to evaluate the combination of slots and poles taking into consideration winding factor and magnetic motive force (MMF). The impact of rotor skewing on slot harmonics reduction is presented mathematically and later verified using finite element method (FEM) simulation. The electromagnetic performance of the two generators are compared using efficiency, thermal and no load induced voltage. Radial electromagnetic forces on tooth and airgap are calculated to assess vibration characteristics of the two machines. Furthermore, the insulation requirements are compared between concentrated and distributed windings using electrical fields generated in stator slot between winding layers. It is observed that both type of windings gives similar performance with concentrated winding providing better ease of insulation.
