Design optimization of single-phase outer-rotor hybrid excitation flux switching motor for electric vehicles

Abstract

Nowadays, in-wheel motors appl vehicles (EVs) propulsion systems have attrac in advance research and development. In-w eliminates the mechanical transmission, diffe drive belts. Thus, in-wheel direct drive prov response, higher efficiency, weight reductio vehicle space. As one of alternative, a new excitation flux switching motor (ORHEFSM) EV is proposed. In this paper, the optimizatio phase 8S-4P outer rotor HEFSM is analysed circuit of initial and final design is comparedb element analysis (FEA). The optimized d produced higher torque which is 138.18 improvement compared to initial design motor and has achieved the target value which 1 maximum power achieved was 17.02kW, whil design motor, it has increased to 41.81kW maximum power is 41kW. The design optim made on the initial design machine shows t enhancement on torque and power.

An Analysis of Iron Flux Bridges Topologies for 12Slot-14Pole HE-FSM

“…Therefore, the machine can possibly improve the output torque and power, enhance flux weakening capability, flux control capability and increase its efficiency [7][8][9]. Numerous combinations of rotor pole and stator slot for HE-FSM have been studied and promote for high-speed application such as 12S-10P HE-FSM configuration is proposed with a separated PM and Ctype stator core, however this design is difficult to manufacture [10][11].…”
