This paper investigates the electromagnetic force and vibration characteristics of a dual-stator consequent-pole hybrid excitation (DSCPHE) motor for electric vehicles. Firstly, the topology and operation principle of the DSCPHE motor are introduced. Subsequently, the temporal and spatial harmonic characteristics of airgap flux and electromagnetic force are derived and analyzed theoretically. The influences of circumferential-segmented winding, consequent-pole rotor, and excitation modes on radial force harmonics are investigated by finite element analysis (FEA). The vibration behaviors of the DSCPHE motor are investigated by the multi-physics FEA model based on mode superposition method. The radial force harmonics that dominate the motor vibration are analyzed. Finally, the DSCPHE motor prototype is built and tested. The motor vibration behaviors are experimentally measured and compared with an interior permanent-magnet synchronous motor (IPMSM) to validate the theoretical results. This work will contribute to the vibration suppression and optimization of the DSCPHE motor.
