Advancement of Modular Rotor Permanent Magnet Flux Switching Motor Using Local Optimization Approach

Abstract

Electric motor performance bound on torque which is the amount of turning power. This element overcomes inertia and sustains acceleration during long distance travel operation for vehicles. High torque motors have the benefit of fast performance response. Permanent magnet flux switching machine (PMFSM) has become a prominent research topic for various applications due to high torque and power capabilities. This paper presents the improved design structure of three phase 12S-10P modular rotor permanent magnet flux switching motor for optimum torque. The initial design structure generated of 34.44Nm which is considered low in maintaining fast response driving operation. Local optimization approach is used to treat design parameters to achieve the optimum output torque. As a result, the modular rotor PMFSM with 0.35kg PM can get optimum torque of 60.49Nm and output power of 23.34kW. This result demonstrates and validates permanent FSM magnet with modular rotor as a viable candidate for optimum torque capable of maintaining long driving acceleration.
