Abstract

The SRM (Switched Reluctance Motor) has a more inherent simple mechanical structure, greater ruggedness and higher efficiency than a conventional AC motor. It is for these reasons that SRM is widely applied in an extensive range of industrial applications. In this paper, SRM is designed and analyzed for EPS (Electrical Power Steering) application. Electrical power steering in a vehicle plays the role of reducing a driver's handling control power. For proper design, a FEM analysis is implemented according to the rotor structure. Using both a FEM and a magnetic circuit analysis, a designed motor is simulated and tested. The effectiveness of the suggested SRM drive for EPS application is verified by the prototype motor drive tests.
