THERMAL ANALYSIS AND TORQUE RIPPLE MINIMIZATION IN SWITCHED RELUCTANCE MOTOR WITH NICKEL-FERRITE MATERIAL

In aircraft electric motor driven fuel delivery system, the motor must be characterized by high power density, reliability, small size, less weight and high speed. The high speed operation, high power density and fault tolerance makes switched reluctance motor an ideal candidate for high speed aerospace applications. This paper investigates the application potential of Nickel and Ferrite materials in high-speed switched reluctance motor. Two configurations of (a) Nickel material with smooth frame and (b) Ferrite material with smooth frame have been studied using finite element analysis to obtain their nodal temperature distributions in different parts of stator and rotor frames. The study reveals that the Ferrite and Nickel metals based stator and rotor frame has a better thermal capability and it provides desirable feature in high speed aerospace applications.
