ABSTRACT:
A linear motor armature includes a sealed metal case having a central chamber formed therein. A lamination stack is disposed within the central chamber and includes a coil assembly disposed within the lamination stack. The central chamber is flooded with an electrically nonconductive fluid, such as oil, for cooling the coil. The cooling oil is flowed in opposing directions to facilitate bidirectional cooling of the coil.
