A power-generating wheel hub includes a hub shaft including a mounting section, and a bobbin including a tubular body sleeved around the mounting section, two flange plates connected respectively to two opposite ends of the tubular body, and a coil wound around the tubular body. Two magnetic yoke disks are sleeved on the mounting section adjacent respectively to outer faces of the flange plates, and each includes a plurality of angularly spaced-apart radial protrusions, and a plurality of indentations each formed between two adjacent ones of the radial protrusions. The indentations in the two magnetic yoke disks are staggered axially with respect to each other. Magnetic yoke claws respectively include radial arms inserted respectively into the indentations in the magnetic yoke disks and abutting against the outer faces of the flange plates, and axial arms extending axially from the respective radial arms and arranged annularly around the coil.

An electrical connector for a dynamo hub includes a fastening component, a hollow insulating component formed with first and second accommodating spaces and a passage, and an electrode unit including at least one electrode plate that has a welding section disposed in the second accommodating space. The fastening component includes a metallic surrounding wall adapted to be sleeved on a hub axle of the dynamo hub, and having an inner surface formed with a positioning protrusion to be inserted into a groove in the hub axle, and a radial through hole extending from the inner surface to the outer surface and to be radially aligned with the groove in the hub axle. The first accommodating space retains the fastening component therein, and the passage is in spatial communication with the first and second accommodating spaces and is radially aligned with the radial through hole.

A small generator with collective multiple magnetic poles includes a magnet, multiple magnetic poles arranged in an annular shape and facing to the magnet, an annular iron core having its outer circumference combined with the multiple magnetic poles spaced apart and equidistantly. The iron core forms magnetic circuits for the magnetic poles so as to let magnetic lines of force to pass through. A sheet-shaped coil is combined on each magnetic pole so that when the magnet is rotated around the iron core with the magnetic poles, the sheet-shaped coil may generate alternate electric current. The sheet-shaped coils are quickly made by mechanical process, with magnetic wires requited for the coils reduced a lot.
