121877.00 Leeson Motors, Premium Series

• All exterior components are 300‑series stainless steel
• Nothing on the motor's exterior is painted or coated in any way
• All sealing components are Viton® for superior chemical resistance
• Full fact nameplate is laser etched on the motor frame ‑ no separately attached nameplate to trap dirt or contaminants
• Endshields are O‑ring sealed to the frame

Designed specifically to meet the demanding sanitation requirements of the pharmaceutical, food processing and beverage industries. These motors are also ideal in clean room and severe chemical‑processing applications involving frequent washdown with nitric acid and caustic lye. In fact, WASHGUARD All‑Stainless Motors include IEEE 841 severe‑duty features right out of the box! Motors have been tested to and passed the IEC IP‑56 test requirements.

• Double lip shaft seals on both ends of TEFC motors (shaft end only on TENV motors)
• Removable hydrophobic breathers in opposite shaft endbell and conduit box equalize pressure without allowing moisture to enter
• Exterior fastener use minimized reducing the number of entry points for moisture. There are no holes in the frame for attaching a nameplate. Bearing lock screws are located inside the motor and the conduit box mounted screws have been eliminated
• Double‑sealed bearings are pre‑lubricated with moisture‑resistant hightemperature grease for long life
• Interior coatings applied to rotor and stator protect against corrosion
• New conduit box mounting system provides optimum sealing
• Ease to clean construction is BISSC Certified for bakery applications
• WASHGUARD efficiencies meet EPACT mandates for non‑exempt motors when tested without shaft seals.
• Windings are immersed and cured in polyester insulating varnish for extra moisture‑resistance
• LEESON's exclusive IRIS™ Inverter‑Rated Insulation System provides extra protection and long life, especially in inverter‑driven applications
• Single‑phase motors use Solid State Sinpac® switch ‑ no mechanical switch contacts to corrode and fail.
• All Washdown Duty motors have Class F Insulation
• Single and three phase motors are UL component recognized ‑ file number E57948, guide number PRGY2.
• CSA Energy Efficiency Verification Program, report number EEV 78720‑1
• Construction is CSA Certified for safety report number LR33543 and listed under BISSC authorization number 769
