OPTIMAL DESIGN OF HIGH PERFORMANCE INTERIOR PM MOTOR FOR ELECTRIC VEHICLE

OPTIMAL DESIGN OF HIGH PERFORMANCE INTERIOR PM MOTOR FOR ELECTRIC VEHICLE

Interior permanent magnet synchronous motors (IPMSMs) are widely used in electric vehicles (EVs) due to their electrical and mechanical characteristics. In addition to the magnetic torque generated by the magnets in the IPMSM motors, a higher torque density is achieved by generating reluctance torque resulting from the inductance variation of the rotor on the d-q axes. Therefore, rotor and magnet geometry have significant effects on the motor performance. In an IPM design, it is often desirable to have maximum torque and flux weakening capability, minimum torque ripple, and low rotor harmonic losses. For this reason, rotor geometry is the most important part that affects the overall performance of the motor. In this study, a 100kW, single layer design V-shape structure IPMSM has been designed. The motor is optimized by considering important geometric data such as rotor geometry, magnet dimensions, bridge and flux barrier. Thus, it is aimed to design an optimum IPM traction motor considering efficiency and cost criteria. Also, the study provides design criteria that can meet low leakage flux and low cogging torque requirements for rotor topologies with V-shaped structures. 2D finite element analyzes have been used to verify the theoretically optimized designs.
