Multiple pole axial field electromagnetic devices
Реферат: ABSTRACT MULTIPLE POLE AXIAL FIELD ELECTROMAGNETIC DEVICES In accordance with the teachings of the present invention, a core element is provided for the rotor or stator of an axial field electromagnetic device such as a motor or generator. The core element of the present invention comprises a cylinder of annular cross section having two annular faces, an axial thickness separating the faces and a plurality of radial slots in one of the faces. In accordance with the present invention, the dimensions of the core element and the slots thereof are sized according to a predetermined relationship. As a result, an electro-magnetic device utilizing the core elements of the present invention is more energy efficient, cheaper and lighter relative to electromagnetic devices of the prior art.
