This study presents a finite element analysis and power electronics co-design for a 12 V low-voltage permanent magnet motor (PMSM) applied to an Electric Power Steering (EPS) system. Finite element method (FEM) analysis is used to evaluate the electromagnetic characteristics, including cogging torque, torque-speed, core losses, and back-EMF distribution. The motor is able to maintain a torque of 2,046 N. m at a speed of 1378.49 rpm with a cogging torque fluctuation of only 87.1 mNm. The system efficiency is recorded at 83.82% with an input power of 352.36 W and an output power of 295.36 W. Integration of power electronics simulations shows the circuit's ability to maintain stable motor torque, with copper losses fluctuating in the range of 40-50 W. The co-design approach can meet the EPS requirements in terms of efficiency, electromagnetic performance, and thermal reliability. © 2025 IEEE.
