Machines for Hybrid Module Applications (original) (raw)

Abstract

Hybrid modules have been adopted by vehicle manufacturers to create hybrid variants of existing models. This paper presents the potential performance of an axial flux permanent magnet machine against typical hybrid module design requirements. A multi physics analytical model is implemented and validated experimentally. This is followed by a parametric design study showing that the axial flux topology provides its maximum specific torques and powers within the available package space. Based on the hybrid module design requirements a design is identified for further development and its performance is confirmed through 3D finite element analysis. It is found that in a package space of 300mm diameter and 90mm length (including casings and water jacket) the axial flux topology offers 390Nm and 98kW for lOs, and 159Nm and 66kW continuously. Future work will include full mechanical design and prototyping of the concept.
