Abstract:

This paper presents the design optimization and characterization of a microscale, permanent-magnet PM generator, capable of supplying 8 W of DC power to a resistive load at a rotational speed of 305,000 rpm. The generator is a three-phase, axial-flux, PM machine, consisting of a stator with Cu surface windings and a multi-pole SmCo PM rotor. Optimization of the machine geometries have resulted in a 30 improvement in power density over a previously reported machine at 120,000 rpm. Furthermore, these design improvements in combination with higher rotational speeds has enabled a 7x improvement in total output power and a net power density of 59 Wcu cm.
