Stator of generation of electricity hub for bicycle and generation of electricity hub for bicycle

摘要

A stator is provided for a bicycle generator hub. The stator comprises a coil bobbin and a plurality of first and second yokes. The first and second yokes are radially arranged ON opposite axial ends of the bobbin. Each of the first and second yokes includes a magnetic pole section extending along an axial direction of the coil bobbin and facing the external circumferential surface of the coil bobbin, an insertion section t extending along the axial direction of the coil bobbin and facing the internal circumferential surface of the coil bobbin and a connecting section extending radial direction of the coil bobbin and connecting the first magnetic pole section and the first insertion section together. The insertion sections of the first yokes have first end portions that abut two corresponding ones of second end portion of the insertion sections of the second yokes.
