Deterministic Optimization Method (DOM) of Permanent Magnet Flux Switching Machine (PMFSM) for Application of Electric Bikes

Abstract

Over the past decades, For various applications, permanent magnet flux switching machines (PMFSM) have attracted revived research interests. The machines not only obtain most merits from the conventional permanent magnet synchronous machines but also have a simple passive and hence robust rotor. The research paper presents a single-phase PMFSM analysis of initial and optimize design for electric bike applications. The 2D-FEA analysis was used to certify the result analysis of these motors. As a result, the design of optimized is significantly lesser magnet volume and high torque compare to the initial motor PMFSM design by using the "deterministic optimization method" (DOM). The optimized motor design has greater average torque performance analysis up to 16% whereas the permanent magnet weight decreased by 28%. As a result, the machine becomes an efficient lightweight motor for electric vehicles and low cost because of a reduction in PM weight.
