The purpose of this paper is to achieve volume and weight minimization while maintaining same level of performance by performing optimization of a CoFe alloy core applied EPS(Electric Power Steering) motor. First, magnetic circuit optimization is conducted using magnetic equivalent circuit method. The core of this paper is to conduct magnetic circuit optimization while maintaining the same level of performance with same input. Other conditions such as rotor shape, PM(Permanent Magnet), number of turns, and etc. are maintained. After determining stator core sizes, optimization is conducted using RSM (Response Surface Method). Finally, an optimized model is suggested that is smaller in volume compared to a motor that uses electrical steel cores while maintaining the same level of performance
