Additional Features

Frame - Full seam weld. Optimum thickness for better heat dissipation. Ends turned for excellent fit to end shields. Frames primed with alkyd primer for corrosion resistance. End Shields - Die cast aluminum with metal bearing bore inserts to provide extra strength and security. Moisture drains are provided in each end shield providing drainage when mounted vertical or horizontal. Base - Heavy duty steel welded to frame. Rotor - Cast aluminum with integrally cast fins for excellent cooling. Keyless design, heat shrunk to shaft, turned for proper air gap, and dynamically balanced, providing for a superior, more efficient electrical design. Stator - Specially treated class "F" and "H" wire used with full slot liner material. Coil heads laced for improved mechanical strength. Stator tested before and after assembly providing optimum electrical integrity. Insulation - Non-hygroscopic, baked-on insulation assures superior electrical strength. Hardware - Zinc chromate plated, high strength, with hex heads. Plating provides exceptional corrosion protection. Bearings - Double shielded. Oversized. Permanently lubricated with moisture resistant grease. Rugged - holds up in tough applications. Conduit Box - Oversized, top mounted, conduit box with F1/F2 conduit connection and grounding lug for ease of installation and safety (F1/F2 conduit box in the end shield for TENV). Shaft - High strength, carbon steel. Connection Diagram - Permanently attached to motor. Fan - Antistatic, bidirectional, corrosion resistant polypropylene. Provides superior cooling with reduced losses due to air movement. Keyed and clamped to prevent movement on the shaft. Single-Phase - Electronic switch mounted in conduit box (or on end shield for TENV) providing convenience and reliability. Certifications - U.L® component recognition and CSA approved. Energy Savings Design - Provided by electrically matched rotor and stator which reduce primary and secondary losses. Leads - Permanently marked providing fast identification.
