ABSTRACT:
A rotor for a dynamoelectric machine, without windings and rotatable about a central longitudinal axis, having an axially extending rotatable body and a toroidal magnet coaxially mounted on the body is constructed to provide magnetic exitation for the rotor. The rotatable body contains a first set of circumferentially spaced axially extending salient poles with circumferentially spaced recesses therebetween and a second set of similar poles at an opposite axial location. The toroidal magnet is coaxially mounted on the body between the first and second set of salient poles. A second toroidal magnet may also be mounted on the body and a magnetic spacer placed in between both toroidal magnets.
