Abstract

This paper presents the analytical study, finite element model, and experimental tests on a three-phase surface-mounted permanent magnet (SPM) synchronous motor designed for the wheel of a hybrid vehicle. The paper focuses on the machine design process so as to achieve the maximum torque-to-current and torque-to-volume ratio. Combining finite element simulations and analytical model, the final solution is obtained as a compromise between conflicting values. The measurements on a SPM motor prototype confirm the results obtained by means of the developed analysis.
