PROBLEM TO BE SOLVED: To lower partial hot spot temperature in a magnetic field winding of a generator, by reducing heat generation. SOLUTION: A method and device for a dynamo coil includes two or more laminated windings in a rotor (10). Each winding (70) is laminated in two or more slots in the radial direction, whose sides are mutually parallel in the rotor (10). Each continual winding respectively has equal width, almost corresponding to the fixed width of each slot, a first winding has a first thickness, and a second winding has a second thickness larger than that of the first thickness. The second winding is adopted in a hot area and, thereby the temperature of a hot region is made to be lowered. COPYRIGHT: (C)2005,JPO&NCIPI |
