Publication number: 20070145850Abstract: A method and apparatus in which a stator (11) and a rotor (12) define a primary air gap (20) for receiving AC flux and at least one source (23, 40), and preferably two sources (23, 24, 40) of DC excitation are positioned for inducing DC flux at opposite ends of the rotor (12). Portions of PM material (17, 17a) are provided as boundaries separating PM rotor pole portions from each other and from reluctance poles. The PM poles (18) and the reluctance poles (19) can be formed with poles of one polarity having enlarged flux paths in relation to flux paths for pole portions of an opposite polarity, the enlarged flux paths communicating with a core of the rotor (12) so as to increase reluctance torque produced by the electric machine. Reluctance torque is increased by providing asymmetrical pole faces. The DC excitation can also use asymmetric poles and asymmetric excitation sources. Several embodiments are disclosed with additional variations.Type: ApplicationFiled: December 20, 2006Publication date: June 28, 2007Inventor: John Hsu

Publication number: 20070145854Abstract: A claw-pole motor according to the present invention has the maximum occupancy ratio of a wound wire by using a rectangular electric wire for the annular coil of a claw-pole-type motor, winding the rectangular electric wire into an almost analogous shape with the cross section of a wound-wire space and setting the rectangular electric wire. Moreover, a lead-out portion is formed by keeping the shape of a lead-out portion as a rectangular wire, the terminal portion of the lead-out portion is deformed into a predetermined connector shape by appropriate processing method and a insulating coating is removed. Thereby, it is possible to greatly decrease man-hours of a terminal connecting portion.Type: ApplicationFiled: December 28, 2006Publication date: June 28, 2007Inventors: Yuji Enomoto, Motoya Ito, Ryoso Masaki, Shoji Ohiwa, Chio Ishihara
