A high-torque low-speed multiphase brushless machine - A perspective application for electric vehicles

This paper presents the design, analysis, simulation, and modeling of a high-torque low-speed multiphase permanent-magnet brushless machine. The machine fits an in-wheel motor arrangement to be used for electric vehicle applications. This paper presents issues regarding the high-level modeling comprised of a transient model in conjunction with their corresponding experimental evaluation. Analysis was made to combine 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 setup. Comprehensive experimental results corroborate the work.
