Analysis of a New Dual Excitation Flux Switching Machine with Outer-Rotor Configuration for Direct Drive EV

Abstract:

This paper presents the design improvement and analysis of dual excitation flux switching machine (DEFSM) with outer-rotor configuration for direct drive electric vehicle (EV). Deterministic design improvement approach based on two-dimensional (2-D) finite element analysis (FEA) is applied to obtain optimal torque density and power density of the proposed machine to meet the requirement of direct drive propulsion of EV. The performance comparison of the original design machine with the improved design machine is also addressed. The improved design machine has achieved 10.19 Nm/kg and 4.74 kW/kg of maximum torque density and maximum power density, respectively..
