Design of Multi-tooth Permanent Magnet Flux Switching Machine for Electric Bicycle Application

Permanent magnet flux-switching machine (PMFSM) with a single-phase multi-tooth design is analyzed in this paper. This paper presents a design comparison between conventional design single-tooth and novel multi-tooth design for a single-phase (PMFSM) with 8S-16P and 4S-8P designed specifically for an electric bicycle applications. The result analysis of this motors has been certified using the 2D-FEA analyses. While, matched with a conventional (FSM), a multi-tooth design motor involves a considerably lesser magnet volume material than a conventional PMFSM machine. Meanwhile, as only half of the number of slot pole and volume of permanent magnets is requisite, and it reveals a high torque performance. However, it shows that the torque capability and performance issues can be increase by using "deterministic optimization method" (DOM).
