Dustproof Motors

Many industrial operations involve the use, production or processing of materials in powder form. Motors used in the automation of such processes are prone to failures when particulates migrate into unprotected bearings and motor cavities.

Empire Magnetics dustproof motors survive in environments where other motors fail.

Features include, built-in O ring seals that eliminate dust leaks at potential penetration points, housing seals including a shaft slinger and seal prevent abrasive dust from entering the bearing, motor insulation that allows operating at 145 degrees C, case temperature (185 degrees C winding temperature) and air fittings for pressurization are supplied; pressure rated to 15 psi to lock out contamination.

Empire Magnetics dustproof motors are available in industry standard size 23, 34, and 42 frame sizes. Note where seal housing affect usable shaft length.

For the most unique and demanding applications, dustproof and abrasive dustproof step motors can be combined with the following environmental options: radiation hardened, waterproof and extended temperature.
