Abstract
A dynamoelectric machine that is both inexpensive and efficient has a rotor including one or more permanent magnets, the working faces of which lie in a spheroid and are centered on the equator of the spheroid. Surrounding the rotor is a brushless stator having spirally wound stator coils. Each coil has a cup-shaped working face centered on said equator and closely spaced from the working faces of the magnet. This dynamoelectric machine can be small, lightweight, and almost twice as efficient as any prior dynamoelectric machine that is equally inexpensive.
