N2 - Axial flux machines have been used for various hybrid applications in the past. Their aspect ratio makes them particularly attractive for integrated starter motors and hub motors. This paper presents a novel machine design that utilises a modular concept to allow one basic set of components to be used for a variety of applications. Should the power of a one-stage unit be too low, additional stages can be added using the same key components. Implementing this technology, axial flux machines with similar aspect ratio than conventional machines can be built but having a 30% higher power-density. This paper describes the design and testing of a double and a single stage machine, rated at 400 200Nm nominal torque respectively. The double stage machine has been designed for application as a generator directly mounted to an engine to form the prime mover unit of series hybrid electric buses. The single stage finds its application in in- wheel traction systems. A weight reduction of up to 50% has been demonstrated compared to conventional motor/generator solutions under favourable operating conditions.
