A high torque low-speed multi-phase brushless machine a perspective application for electric vehicles

This work presents the design, analysis, simulation and modeling of a high-torque low-speed multi-phase permanent magnet brushless machine. The machine fits an in-wheel motor arrangement to be used for electric vehicle applications. The paper presents issues regarding the high level modeling comprised of a transient model in conjunction with their corresponding experimental evaluation. Analysis was made to put together the modeling efforts with the expected behavior concerned with mutual inductance and armature reaction effects, so as to have realistic simulation results verified by the experimental set-up. Comprehensive experimental results corroborate the work.
