Frame and End Shields

Cast iron frame and end shields for exceptional structural integrity, with UL approved condensation/breather drains on 404T – 449T frames. Lifting eyebolts are included for motors > 75 lbs.


A unique rotor design provides improved efficiency while larger bars and end rings reduce resistance for lower rotor losses. Each die cast aluminum rotor assembly is dynamically balanced for extended bearing life, and includes a high strength carbon steel (C1045) shaft for maximum rotor performance.


This insulation system meets or exceeds NEMA MG1-2010, Part 31, making all motors suitable for operation with adjustable frequency drives. All windings are tested for CIV.
