As the quality characteristics of electric power steering (EPS) motors, the high average torque, small torque ripple, and small cogging torque are required. This paper proposes a slot-less permanent magnet (PM) synchronous motor for EPS motor, which has theoretically 0 cogging torque. Magnet volume and coil volume are determined by 2-D finite element (FE) analysis. The 3-D FE analysis shows that it has the average torque of 2.667Nm and the torque ripple of 0.053Nm. Therefore, it is verified that the proposed motor has a great decrease of torque ripple.
