| Abstract |
Winding method differs majorly by number of slots per phase per pole(NSPP). If those of NSPP are integer, Concentrated Winding and Distributed Windings are used. Distributed Windings can be further classified into Lap Winding and Concentric winding according to the pitch distribution of coils. The number of turns and the number of pitch are same between each coil in Lap Winding with Fractional(Short) Pitch. On the other hand, the number of turns in each coil can be different for Concentric Winding maintaining the number of turns per pole. Air-gap Magnetic Motive Force(MMF) distribution appears differently depending on the ratio of turns in each coil. In this paper, the No-load performance of Permanent Magnet Synchronous Motor with Lap Winding and Concentric winding is compared. Winding Factors are calculated to consider the MMF distribution analytically for each winding case. The electromagnetic performance of each winding case is analyzed through 2D Finite Element Analysis(FEA). |
