In this paper, traction motor for Electric Vehicle(EV) is designed according to system requirements, and high power density motor is designed and compared in the same system. The design specifications of the standard motor are Interior Permanent magnet Synchronous Motor(IPMSM) of 8pole-48slot of 100kW class, 280Nm for maximum torque and 12,000rpm for maximum speed. Design of the motor was aimed at maximizing the torque density using response Surface Methodology (RSM). The specifications of the high power density motors to be compared were determined after increasing the reduction gear ratio in the same system specification. Based on the assumption that the carrier frequency of the inverter is the same, the number of poles is determined according to the maximum speed of the motor and the 6pole-36slot model is designed through the same process. The characteristics of the motor such as power density and efficiency were compared according to the design results of the two motors.
