N2 - This paper proposes a dual-stator five-phase permanent magnet synchronous motor with hybrid spoke-vernier type rotor for electric vehicles (EVs) traction applications. The proposed machine can achieve high torque density, high-power factor, and wide speed range operation with a hybrid spoke-vernier type PM rotor. The first design (Initial Design) consists of an outer stator having twenty slots that carry a four-pole, five-phase concentrated winding with an inner spoke-type PM rotor supported by a magnetic hub. The latter is utilized in the second design (2nd Design) to house a set of flux barriers and additional pieces of PMs arranged in a vernier type configuration, to obtain a hybrid rotor structure. From the 2nd Design, the proposed machine (Proposed Design) is obtained. The proposed design is equipped with a second inner stator core that also houses a four-pole, five-phase concentrated winding. The three machines were modelled for ac magnetic transient analysis using the 2-D Finite Element Method (FEM). The influence of different electromagnetic parameters on the traction performance of the proposed machine is evaluated. The Finite Element Analysis (FEA) results demonstrate the effectiveness of the proposed machine, which has positioned itself to be a strong candidate in EVs traction applications.
