Design Comparison of Fractional-Slot IPM Machine Types for an Electric Power Steering Application

Abstract:

Article Preview

This paper deals with the design comparison of interior permanent magnet (IPM) motors with fractional-slot winding configurations for an electric power steering (EPS) application. By making comparisons of these configurations based on cogging torque, torque ripple, average torque, and efficiency, an IPM rotor configuration has been chosen for use as a prototype motor. The Taguchi parameter method coupled with the finite element analysis (FEA) is employed to achieve the desired performance requirements within a reasonable geometry. To assess the rated current and thermal behavior of the motor, the lumped circuit models are conducted.
