Abstract
A rotating machine configurable as a pure DC generator for use in various applications, including recharging batteries in battery operated portable devices. The generator consists of a pair of permanent magnets which are mounted on two rotating magnetic ferrous metal hubs. The magnets are aligned so that they have the same polarity facing each other. The hubs, including the magnets, rotate around a stationary toroidal coil, which creates a magnetic flux. The flux from the two magnets cuts the conductor to the toroidal coil in a same direction upon rotation of the hubs, creating an emf (current) which is always in the same direction. Thus, a direct current is created, without the need for commutation or rectification. The input and output functions of the generator may be reversed to enable the generator to function as a DC motor.
