Efficiency optimization of an axial flux permanent-magnet synchronous generator with concentrated pole windings

摘要

In this paper, the efficiency optimization of an axial flux permanent-magnet synchronous generator with concentrated pole windings is examined for a 3.6 kW/2000 rpm combined heat and power application. A study of the influence of a limited set of geometry parameters on the efficiency of this type of machine is done, using both analytical and finite element methods. Finally, the results of both methods are compared with measurements on a prototype.
