ABSTRACT:
Electromagnetic motor with a slider that moves linearly with respect to the stator in either direction. Embodiments include slider internal or external the stator. Slider includes one magnetic flux producing element in all embodiments. Internal slider embodiments stator includes a minimum of three magnetic flux producing elements and a maximum of four such elements. External slider embodiments stator includes two magnetic flux producing elements. All embodiments provide positive slider return to center at rest position. In internal slider embodiments the slider is centered within the stator resulting from either: a combination of a repelling force from a single magnetic flux producing element in opposition to gravitational pull on the slider due to its weight; or equal and opposite repelling forces on opposite sides of the stator from a magnetic flux producing element on opposite sides of the stator all three elements in longitudinal alignment with each other.
