Patent attributes
The present invention is a direct current generating machine that eliminates the need for brushes or other mechanical commutators. A pair of opposed, spaced apart rotatable rotors, each carrying a plurality of bar magnets, are synchronously rotated about a common axis of rotation. A stationary electrically conducting wire extends through the axis of rotation, and radially outwardly therefrom, between the rotating magnetic field. In another embodiment the bar magnets are replaced by pieces of steel which interrupt a unidirectional, magnetic field created by a magnet. The magnet used to create the unidirectional, magnetic field may be an electromagnet. The resultant electrical signal generated in the conductor is unidirectional. The present invention may be used to create brushless DC electrical signals, brushless three-phase DC electrical signals, or a plurality of DC and/or inverted DC signals.
