Abstract
A disc motor includes an output shaft, a coil disc, an electric current supplying section, and a magnet. The coil disc is disc-shaped. The coil disc includes an at least two-layer structure having a first layer and a second layer. The coil disc includes a coil having a plurality of partial coil sections each extending outward in a radial direction of the output shaft and connecting sections each connecting together two partial coil sections. The electric current supplying section supplies an electric current to the coil. The magnet is disposed in opposition to the plurality of partial coil sections. The plurality of partial coil sections includes first partial coil sections formed on the first layer and second partial coil sections formed on the second layer. The first partial coil sections provide a total number different from that of the second partial coil sections.
