Abstract: A reciprocating induction linear motor device is disclosed, built with transformer silicon laminated iron, a closed magnetic circuit, without an air gap, with two coils and an electrically conducting ring that oscillates in the central column of the transformer. The oscillation of the ring is given by the induction of enormous currents in it and the magnetic field generated by these currents when interacting with the primary winding of the transformer.
