Abstract

Interior V-type permanent magnet (PM) machines are widely used in new energy vehicles due to their merits of high efficiency, high power density, and wide speed range. To meet the requirement of the elderly mobility scooter, a 380V/2.2kW V-type interior PM machine is designed and analyzed in this paper. Firstly, the structure parameters of the Vtype interior PM machine are derived. Then, the basic electromagnetic properties of the PM machine including the no-load air gap flux density, back-EMF, armature reaction flux density, output torque, etc. are investigated. Finally, the dimensions of the V-type PM including the width, thickness, and inclination angle are optimized to obtain better electromagnetic performance. Compared with the performance before optimization, the torque ripple of the PM machine is reduced by 33.53% and the efficiency is improved by 0.88% after optimization.
