Leeson Electric has launched the next generation Extreme Duck Motor. The new design is built to ensure that liquids don’t penetrate the motors in any mounting position and the motor has colored leads for ease of installation.

“By listening to customers’ feedback we designed this next generation motor with distinct features making it an ideal motor for use in the food processing, pharmaceutical, packaging and beverage industries,” said Steve Bernhardt, Leeson Electric lead application engineer.

 A shaft seal that underwent a year of testing – 8,760 hours – is one of the motor’s unique features. Other features include:

·         Lead wires are non-wicking and are colored and numbered for easy identification during installation

·         Installable in all mounting positions

·         Standard dual voltage and dual rotation

·         New encapsulation process with better materials ensures complete filling of the motors and curing of the epoxy encapsulation

·         All stainless steel exterior

·         Nameplate information is permanently etched into the frame

·         Conduit box on TEFC motors rotates 360 degrees

·         Inverter Duty IRISTM insulation system

·         Corrosion resistant coating applied to rotor


In addition to Leeson’s normal in-process testing, each motor is pressure tested before leaving the plant, to ensure the motor is completely sealed to prevent the ingress of liquids. The motor meets the Energy Independence Security Act mandate going into effect June 1, 2016.

Benefits of the Next Generation Extreme Duck Motor include:

·         Numbered lead wires enable easier readability and identification, reducing installation time and costs

·         Pressure testing guarantees liquids don’t penetrate the motor, increasing motor life and virtually eliminating plant down time

·         Eliminating corrosion ensures longer motor life and lessens operating costs

·         Washdown motors enhance flexibility and durability, yielding to minimal operating expenses while increasing uptime


This motor is designed for use in food processing and other applications where motors are exposed to frequent washdown, common cleaning and sanitizing chemicals and high humidity. Washdown motors provide durability and flexibility to help maximize uptime and reduce overall operating costs in these and many other demanding applications where general purpose motors will not survive.
