Electrical Power Steering(EPS) system that assist driver’s vehicle steering is one of the core parts of the vehicle. In addition, the EPS motors require very low vibration and high performance for vehicle stability. In this paper, the electrical parameters of EPS motor is converted into the function of the rotor shape. Using this function, the efficiency and thermal characteristics of the EPS motor are analyzed according to the rotor shape. Then, the design point with high efficiency and improved thermal characteristics is determined as the sizing effect. Then, the improved model is designed. Finally the validity of the improvement model is confirmed by comparing the efficiency and thermal characteristics of the improved model with the existing model.
