Abstract

A compound-structure permanent-magnet synchronous machine (CS-PMSM) system used for hybrid electric vehicles (HEVs) enables the combustion engine (ICE) to operate at optimum efficiency independent of road conditions, thus decreasing the emissions and fuel consumption. The key part CS-PMSM is a high integration of two electric machines. The connection way of the CS-PMSM in the HEV system is discussed. Different topologies of the CS-PMSM are put forward and evaluated by finite-element method (FEM) respectively. A downsized axial-axial flux prototype machine was designed and manufactured for the testing facilities and concept validation. The performance, efficiency, temperature and the function of the axial-axial flux CS-PMSM prototype are measured and analyzed.
