Abstract :
This paper presents an axial-flux induction motor which has a single stator and two squirrel-cage rotors mounted on individual, independents shafts driving two wheels of an electric vehicle. This novel induction machine inherently behaves as an electromagnetic differential motor and thereby performs the function of both the engine and the differential of a conventional vehicle. Features of the proposed motor topology are described, and an equivalent circuit is derived from the analysis of the magnetic and electrical behaviour of the machine. Basic machine design and characteristics of a 20 kW motor prototype are finally discussed
