Abstract
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.
