Patent number: 6838800Abstract: The stator includes core back iron cores disposed on outer circumferential sides between a plurality of teeth iron cores disposed at regular intervals of a predetermined distance in a predetermined circumferential direction. A stator winding is disposed on inner circumferential sides between the plurality of teeth iron cores. The stator winding is constituted by a plurality of wire bundles each of which is a bundle of a predetermined number of electric wires and which are connected in parallel with one another. The wire bundles are set so that the number of electric wires constituting a wire bundle located on the inner circumferential side between adjacent teeth iron cores is smaller than the number of electric wires constituting a wire bundle located on the outer circumferential side. Hence, the ratio (L/A) of the circumferential length L of each wire bundle to the sectional area A thereof is set at a value in a predetermined allowable range.Type: GrantFiled: October 2, 2002Date of Patent: January 4, 2005Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Mitsuyoshi Takao, Hirofumi Atarashi, Yasuhiro Endo, Akira Kato, Toshinori Tsukamoto, Keisuke Urushihara, Takeo Arai, Takeo Fukuda, Kazuaki Igarashi, Hiroyuki Kikuchi

Patent number: 6791224Abstract: A stator winding which copes with high output and miniaturization turns formed by winding a wire sheaf of a plurality of fine wires bundled together, in an approximately rhombic shape, wherein the turns are arranged so as to be sequentially shifted in the direction of one diagonal of the rhombic shape, to thereby form an approximately rhombic shape coil segment comprising a continuous length of the wire sheaf. A plurality of coil segments are then sequentially shifted and overlapped on one diagonal to form a band shaped body, and a hollow cylindrical body is then formed by rolling the band shaped body into a circular shape. The winding is characterized in that with each turn, opposite end portions located in the direction of an other diagonal orthogonal to the direction of the one diagonal have U-shape bent back portions.Type: GrantFiled: July 19, 2000Date of Patent: September 14, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masaru Ozawa, Takeo Fukuda
