Abstract: A rotor core comprises a round rotor main body forming a rotor and salient poles provided along the periphery of the main body. The rotor core is constituted by forming unit rotors spaced at salient pole intervals such that a prescribed number of salient poles are removed from all the salient poles, by winding wires on salient poles of the unit rotors which are separated, and by combining the unit rotors with the cores mutually shifted at prescribed angle to assemble them into a rotor core.

Abstract: A distributed air gap material for an induction device in power systems for minimizing fringe losses, mechanical losses, vibration and noise in the core. The distributed air gap material occupies a selected portion of the core and is formed of a finely divided magnetic material in a matrix of a dielectric material. The air gap material has a zone of transition in which the magnetic permeability values vary within the air gap material.

Abstract: An electrical machine, which may be a motor and/or a generator has a rotor mounted to rotate about an axis. A plurality of magnetic poles are spaced circumferentially around the rotor in the bore. The rotor comprises a shell shaped to provide a toroidal bore centered on the axis. A slit extends circumferentially around the rotor. The slit penetrates through the shell into the bore. The electrical machine also includes a stator that is supported in the bore by one or more supports extending through the slit of the rotor. The stator carries plural windings that are spaced apart around the bore.
