Research on Combinations of Primary and Secondary Pole Numbers for Linear Switched-Flux PM Machines with Odd Pole Number of Primary

Abstract:

Based on a simple analytical model, combinations of primary and secondary pole numbers for linear switched-flux permanent magnet (LSFPM) machines with odd pole number of primary are compared, with respect to back electromotive force (EMF) and electromagnetic thrust force. The winding configurations are also determined according to the coil-EMF vector diagram. Based on optimized LSFPM machines, some basic electromagnetic performances are compared in LSFPM machines with 9 primary poles. It is shown that the secondary pole number should be close to the primary pole number and the higher secondary poles can lead to a better performance.
