Modelling of Twin Rotor Axial Flux Induction Machine and its Application as Differential in Electrical Vehicles

Abstract: This paper proposes the modelling of Single Air gap Axial Flux Induction Machine and it is extended to Twin Rotor Axial Flux Induction Machine. It is also proposed to use a Twin Rotor Axial Flux induction Machine as a replacement for existing conventional mechanical differential. The possibility of having shorter axial length and two independent rotors in a single machine favors for above application. These motors are used as wheel motors and this also becomes one credential for using them in electric vehicle applications. Furthermore it is compact and has high power density. The present work is simulated in MATLAB environment.
