Abstract:
An electric motor apparatus that includes a disk with an increased mechanical advantage to the attached axle, with donut-shaped permanent magnets, windings, a fulcrum (A.K.A. axle), bearings, a commutator, and a single bearing conductor that replaces the brushes. The center axis consists of the windings and spools with the axis of the windings placed coradial in orbit around the fulcrum of a disk. The donut-shaped permanent magnets are cut with a slot to allow passage of the disk, spools, and windings. When windings of magnet wire are inserted with windings around the spools such that the center points of the faces of the spools are concentric to the same radius of the disk and pass through the center of a donut-shaped permanent magnet, and the windings are electrified with the correct polarity, the windings are repulsed magnetically in the direction of rotation of the orbit around the fulcrum (A.K.A. axle) causing the disk and axle to rotate. Upon completion of the fractional rotation, the original set of windings is deenergized and another set of windings is energized further rotating the disk and axle.
