Title:
HUB DYNAMO AND BICYCLE COMPRISING HUB DYNAMO
Document Type and Number:
Japanese Patent JP2016171723
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hub dynamo capable of smoothly rotating a rotor.SOLUTION: A hub dynamo 10 comprises: a magnet part 20 as a columnar stator fixed on an axle 18; a coil part 17, as a rotor surrounding the outer peripheral surface of the stator, having a tubular shape around the axle; and a transmission mechanism for transmitting rotation of a hub 15 of a wheel to the coil part 17 so that the coil part 17 is made to rotate around the axle 18 with respect to the magnet part 20. The magnet part 20 includes a plurality of columnar magnets arranged so as to form a cylindrical shape. The coil part 17 includes a coreless coil obtained by winding a lead wire so as to form a tubular shape. The stator may be constituted by the coil part 17; the rotor may be constituted by the magnet part 20.SELECTED DRAWING: Figure 1
