As enforced the regulation of fuel efficiency, the electrification of automotive components in internal combustion vehicle has been

applied instead of hydraulic pressure. A typical example of such parts is the EPS (electric power steering), and it is applied to most

automotive at present. In electric power steering system, the core component is motor. The reduction of cogging torque and torque

ripple is required to improve steering feeling and reduce NVH (Noise Vibration Harshness) in EPS. Generally the skewed design of

stator or rotor is applied in order to reduce cogging torque and torque ripple. This paper propose the design and analysis methodology

of Brusheless PMSM (Permanent Magnet Synchronous Motor) which is applied to skewed stator. The proposed methodology is as

follows: First Intial Design PMSM with skewed stator for EPS, Second Optimal design using RSM (Response surface method), Third

Performance Analysis such as Phase Back EMF, Inductance, Load torque using FEA (Finite Element Method). Finally, the reliability

of proposed design methodology will be verified through the experiments of prototype sample.
