Abstract
A first bias magnetic flux may be communicated between a first axial pole and a first axial facing surface of the body. A second bias magnetic flux may be communicated between a second axial pole and a second axial facing surface of the body. A time-varying axial control magnetic flux may be communicated through the first and second axial facing surfaces of the body, and may be generated in a magnetic circuit including the body, the first and second axial poles, and an axial magnetic backiron. The first and second axial poles may include axial pole laminated inserts composed of electrically isolated steel laminations stacked along the body axis. The axial magnetic backiron may include laminated inserts composed of electrically isolated steel laminations stacked in the direction tangential to the body axis. The axial pole laminated inserts may be magnetically coupled to the axial magnetic backiron laminated inserts.
