AC Motors

1/8 to 3 HP Designed for all general purpose, hazardous industrial applications

Reliance® Electric S-2000 XP motors are designed to operate in harsh environments that contain gas, vapor, dust, fibers, flyings, or other materials that may have explosive properties. These motors are constructed to withstand an internal explosion, to prevent ignition of the environment surrounding the motor as a result of an internal explosion, and to operate with external surface temperatures that will not ignite the surrounding environment. With a Reliance S-2000 XP motor you have Reliance Electric’s many years of explosion-proof motor experience behind you. You are assured of a long lasting, reliable motor for your application.

Standard 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.
• 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 - Removable, oversized conduit box with grounding lug for ease of installation and safety.
• 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.
• Leads - Permanently marked providing fast identification.
• Temperature Limiting Devices - Thermal protectors or thermostats included as standard. Assures rated skin temperature, providing maximum safety.
• Certifications - U.L.Æ and CSA approved for hazardous locations.
• Energy Saving Design - Provided by electrically matched rotor and stator which reduce primary and secondary losses.
