Frame and End Shields

Frame and bearing housings – Cast iron construction for exceptional structural integrity and corrosion protection. Condensation T-drains provided. Lifting eyebolts are included for motors > 75 lbs.

Rotor

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

Insulation

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.
