Leeson M1125279.00 0.25 HP, 250 RPM DC gearmotor with 32 NEMA frame and Totally Enclosed Non-Ventilated (TENV) enclosure. Operates on 90V DC. Permanent magnet DC gearmotor designed for SCR drive control applications. Class F insulation, ball bearings.

Leeson WASHGUARD

motors are designed for extended life in applications requiring regular washdown or otherwise wet environments. WASHGUARD motors retard the entrance of water. Extra protection for the motor’s interior prevents rust and corrosion build-up and releases trapped moisture to insure a longer life than possible with a standard motor. For optimum seal life, these right-angle gearmotors have a lubrication breather positioned for horizontal mounting. For other mountings, the breather plug must be reoriented by using a 90 1/8 NPT taper pipe elbow. See page 97 or 106 for diagram. Overhung load capacities shown are at center of the output shaft. The motor’s stall torque exceeds recommended full load torques for the gearboxes. A current limiting device should be used to prevent damage to the gear sets.

Leeson gearbox output shafts are 303 stainless steel. Frame, endshields, armature and interior components protected by enamel and polyester compounds for resistance to moisture, acids, alkalies and oil. Cast conduit box with threaded conduit holes and Nitrile gaskets keep water out. The conduit box cover is made from 304 stainless steel. For any condensation that may accumulate inside the motor, a one-way stainless steel vapor vent is provided. All hardware is stainless steel. Motor painted with epoxy for superior corrosion resistance and protection. Machined fits between the endbells and motor frame are sealed with gaskets. Thru-bolt heads and nuts sealed with fiber washers. O-rings under each threaded brush cover. This worm-type right-angle gearing features hardened, steel worm with bronze worm wheel for long life and quiet operation. Precision machined aluminum housings are used. Gearbox has all ball bearings. The housing is sealed and lubrication is permanent with an oil bath.
