Abstract—In aircraft electric motor driven fuel delivery system, the motor must be characterized by high power density, reliability, less size, less weight and high speed (Radun, 1992). The high speed operation, fault tolerance, high power density makes switched reluctance motor an ideal candidate for high speed aerospace applications. This paper investigates the application potential of soft magnetic composite material (SOMALOY 500) in high-speed switched reluctance motor. Two configurations: (1) all sheet metal with smooth frame and ribbed frame, (2) all Soft magnetic composite material with smooth frame and ribbed frame have been studied using finite element analysis to obtain their nodal temperature distributions in different parts with two different stator frames such as stator with smooth frame and stator with ribbed frame and mode shapes and mode frequencies. The study reveals that the all soft magnetic composite configuration with ribbed stator frame has a better thermal capability and lesser vibration of stator that may result in low acoustic level a desirable feature in high speed aerospace applications.
