ABSTRACT:
The present invention relates to a dynamo-electric machine which includes a plurality of permanent magnets arranged sequentially with like poles adjacent and spaced from each other by a plurality of spacers of magnetically soft material. Motive coils are located generally adjacent to the permanent magnets so that when energized one pole of the induced magnetic field will provide attractive forces toward one of the permanent magnets while the opposite pole of the induced magnetic field will produce repulsion forces from the like pole of the adjacent permanent magnet. A commutator device is provided for properly energizing selected ones of the motive coils in proper polarity. A plurality of generator coils are located adjacent to the permanent magnets for cutting the magnetic lines of flux emanating therefrom so as to generate an induced voltage at an output thereof responsive to the relative motion between the generator coils and the permanent magnets. The relative motion between the permanent magnets and the motive coils is limited to coplanar opposing motion for increasing the effective relative motion therebetween.
