Abstract

Novel stator permanent magnet synchronous machines (SPMSMs) which adopt doubly salient stator and rotor structure and non-overlapping winding are investigated in this paper. Several new SPMSMs topologies are developed, including magnets in the stator poles and on the stator pole surface, respectively. It shows that amongst various SPMSMs, the surface-mounted SPMSM exhibits higher torque density, lower torque ripple and more sinusoidal back-EMF than the pole-mounted SPMSM under the condition of same copper loss.
