Abstract

This paper proposes a dual-stator five-phase permanent magnet synchronous machine (DSFP-PMSM) for the purpose of improving the electromagnetic performance. The five-phase concentrated-coil windings are designed by a phase-group configuration method. Two stators with the same slot/teeth construction are arranged to be shifted by one stator tooth width to enhance flux focus effects and reduce the torque ripple. A novel winding end connection method, by changing star connection to delta connection of inner stator winding, is proposed to make the same phase of back EMFs in the inner and outer windings, thereby only one set of inverter is required to reduce control complexity. To evaluate the effectiveness of the proposed model, a quantitative comparison is carried out by comparing to a referenced model at the same operating conditions. All electromagnetic performance including back EMF, cogging torque, and electromagnetic torque are analyzed by a finite element method (FEM).
