A comparison of torque characteristics about pole combination (N1/N2) for the EPS drive BLDC motor

摘要

The EPS (Electric Power Steering) requires saving energy of vehicle. But EPS motor is closed with handle, so there are severe requirement in the noise, the vibration, the torque ripple, and so on. This paper describes for the new design method by using electromagnetic FEM calculation techniques to the EPS motor design.
