ABSTRACT:
A dynamoelectric machine having a large magnetic gap between the rotor and the stator includes a slotless stator windings located within the large magnetic gap, and a mgnetic assembly consisting of radially aligned permanent magnets separated by non-magnetic material. The magnetic pole circumferential length and the radial gap length are proportioned such that the permanent magnets are operated at or near their maximum energy product.
