GA is heading a team to support the Office of Naval Research to construct a ¼ scale 5000 hp superconducting DC Homopolar motor.

AMT is excited to participate in this development by providing the critical sliding brush assembly. These critical sliding contacts tranfer over 300 amps of current to the internal magnetic fields.

With the technical advancements in reliable sliding contact brush married with a liquid-cryogen-free superconducting magnet system, a prototype will be developed to support a Navy vessel for the Advanced Lightweight Influence Sweep System (ALISS) countermine group. Precision machining, EDM and turning was required to produce more than 600 sets of this precision assembly. Silver plating is utilized to minimize the oxidation.
