Die Cast Aluminum
Cast iron construction for exceptional structural integrity and corrosion resistance. Condensation T-drains are provided. Lifting eyebolts are included for frames > 75 lbs.
A unique rotor bar 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.
