Frame and End Shields

Cast iron construction for exceptional structural integrity & corrosion resistance, equipped with integrally cast feet. Condensation T-drains are provided. Lifting eyebolts are included with motors > 75 lbs. Cast iron construction, polycarbonate fan, zinc-plated hardware, epoxy enamel paint and stainless steel nameplate resist rust and corrosion.

Rotor

Die cast copper rotor or die cast aluminum that meets or exceeds NEMA MG1 Table 12-12 efficiencies.

Each 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.
