Claw-pole dynamo with radially offset yoke arms

Parasitic current during the clamp generator, suppression generation generating electrode, and an generating efficiency. The generator magnetic yoke (21) is arranged in winding (20) axial direction of each of two sides platy folding sheet (32) is plurality groups first and permian layer magnetic yoke (30); (31). At the same time, the platy folding sheet (32) comprises with an axial direction one side or other side to sleeps poorly extend and the permanent magnets (9) and winding (20) magnetic yoke outer part (32a), display, configured with a magnetic yoke (32a) magnetic the axial direction one side or other side magnetic yoke the end part (32b). The region; multiple groups first and permian layer magnetic yoke (30); (31); each magnetic yoke end part (32b) in axial direction of, wherein axial direction contact end; and outer yoke part (32a) alternating along the circumferential direction is.
