Abstract
An electromagnetic actuator includes a body having a rotational axis, a first pole adjacent an end facing surface of the body, and a second pole adjacent a lateral facing surface of the body. The poles are adapted to communicate magnetic flux with the body. The body, the first pole, and the second pole define an axial magnetic control circuit. The actuator includes a plurality of radial poles adjacent the lateral facing surface of the body and adapted to communicate magnetic flux with the body. The body and the plurality of radial poles define a plurality of radial magnetic control circuits. The plurality of radial poles are adapted to communicate magnetic fluxes with the body and at least one of the first pole or the second pole. The body, the plurality of radial poles, and at least one of the first pole or the second pole define a magnetic bias circuit.
