Closed-Form Solutions Using Offset Angle for Winding Configurations of Flux-Switching Permanent Magnet Machines.

This paper presents a novel perspective to understand different winding configurations of flux-switching permanent magnet (FSPM) machines. A simple analytical method is used for the calculation of total offset angle of flux linkages by taking into account an offset angle of stator slot and rotor poles. The closed-form solution is presented to find the sequence of phase windings. The 12-slot/10-pole and 12-slot/13-pole FSPM machines are conceptually segregated into two sets of 6-slot/10-pole and 6-slot/13-pole machines, respectively. This is used to address even harmonic elimination and winding configuration properties in even and odd number of rotor pole configurations. Finite element analysis and experimental results verify the concept. [ABSTRACT FROM AUTHOR]
