| Abstract |
This paper presents the design and and performance characteristics of the interior permanent magnet synchronous motor (IPMSM) with double V shape PM rotor structure for high performance electrical vehicle traction applications. The performance of a 150kW IPMSM is required to operate a constant power speed range (CPSR) of over 3 within the condition of inverter capability. The interior PM rotor structure shape considering the magnetic flux weakening control in a given specific output performance and constant power speed ratio (CPSR) is determined in the response surface method (RSM) optimization process for the rotor design of a two-layer V-shaped permanent magnet array. The performance characteristics such as magnetic flux density, cogging torque, d-q axis inductance, torque, power and torque ripple were computed by FEM software. To verify the performance characteristics for EV traction applications. The designed prototype IPMSM operating with the flux weakening range from the base speed of 4000[rpm] to the maximum speed of 12000[rpm] was manufactured and investigated. Performance characteristics were compared with the FEM results and experimental values. |
