STATOR OF POWER GENERATION HUB FOR BICYCLE AND POWER GENERATION HUB FOR BICYCLE

摘要

PROBLEM TO BE SOLVED: To simplify the configuration of a power generation hub for a bicycle.;SOLUTION: A stator 13 of a power generation hub 10 for a bicycle includes a hub shaft 15, an annular member 16, a first yoke 18, a second yoke 19, and a third yoke 20. The annular member 16 includes a through hole 16d into which the hub shaft 15 is inserted. The first yoke 18 includes a first extension part 24a that extends from one end side in an arrow B direction (axial direction) of the annular member 16 toward the other end side, being provided not to rotate relative to the annular member 16. The second yoke 19 includes a second extension part 26a that extends to one end side from the other end side in the arrow B direction of the annular member 16, being provided not to rotate relative to the annular member 16. The third yoke 20 is arranged at the through hole 16d to magnetically couple the first yoke 18 and the second yoke 19 together, being connected to both the annular member 16 and the hub shaft 15 for no rotation.;COPYRIGHT: (C)2012,JPO&INPIT
