Several magnetic circuit configurations (radial-field, axial-field, flux-squeezing, homopolar) have been proposed in the design of high-speed, low-power electrical generators for unmanned aircraft and spacecraft. The relative merits of these configurations are subjected to a quantitative investigation over the speed range 10000-100000 rev/min and power range 250 W-10 kW. The advantages of incorporating new high-energy-density magnetic materials are described. It is concluded that the flux-squeezing and conventional radial-field magnetic circuit configurations yield designs with minimum volume over the power and speed ranges considered.
