Company: Nercon Eng. & Mfg. Inc., Neenah, WI
Equipment Snapshot: Nercon is now using Marathon MicroMax motors and Grove IRONMAN worm gear reducers in its conveyor systems. The Marathon MicroMax motor has a three-phase, totally enclosed inverter (vector) duty. With a 1000:1 constant torque (TENV), 20:1 constant torque (TEFC) motors are designed for direct replacement of PMDC or any other variable-speed application requiring up to a 1000:1 constant torque speed range. Features include Class H insulation with CR200 magnet wire; UL-recognized, CSA-certified and CE mark; and continuous duty at 40° C ambient. IRONMAN worm gear reducers are built with Viton double-lip seals to provide long life and resistance to high temperatures, abrasion and chemicals. Completely leak-test inspected, they feature O-rings on input and output covers that eliminate gaskets, sealants and leaks. Additional features include tapered roller bearings on output shaft for high overhung and thrust load capacities; a high-capacity oil reservoir; and push-off holes drilled and tapped into a quill flange for quick and easy motor removal.
