ABSTRACT:
Electromagnetic motor with a piston that moves linearly with respect to the stator in either direction. Embodiments include a piston internal or external the stator. The piston includes one or more magnetic flux producing elements in all embodiments, with some embodiments having a ferro-magnetic plate on either side of the flux producing element. Further, in all embodiments the stator includes three magnetic flux producing elements with either two coils with one or more magnets therebetween or with the two coils and a coil magnet substitute therebetween. All embodiments provide positive piston return to a center at rest position. In all embodiments the piston is centered with respect to the stator resulting from either magnetic interaction between the piston and stator magnets, or between the piston magnet and the stator magnet substitute coil.
