Abstract
An electromagnetic actuator assembly for moving heavy loads and running on electromagnetic energy has at least one piston providing movement of heavy loads. Two pairs of THK linear rails controls the electromagnetic actuator assembly. A pair of drive motor coil assemblies provides a force to the two pairs of THK linear rails. A foundation houses an internal tube that contains a plurality of cables. A housing mount weldment connects the plurality of cables to a pair of electrical connections of the pair of drive motor coil assemblies, and allows the plurality of cables to extend when traveling back and forth inside the internal tube. The housing mount weldment has a plurality of openings for access to the plurality of cables. An exposed linear encoder runs along the at least one piston, comprising at least one scale providing positional feedback of the at least one piston.
