Abstract
This paper presents a novel double-fed flux modulation (DF-FM) machine which offers an effective electric solution for electric vehicle (EV) propulsion. This design can realize adjusted speed and torque transmission without planetary gearbox and brush system in EVs. Main advantages of this design involve high torque density, wide speed range operation and low friction loss. The steady and transient performance of this newly proposed DF-FM machine is analyzed using finite element method (FEM).
