Us Motors S5E2ACR 5 Hp Three Phase Tefc Ac Motor 184 Frame

Product Description

The US MOTORS S5E2ACR is a three-phase, premium-efficient AC motor built for continuous-duty industrial and commercial applications. Rated at 5 horsepower and 1750 RPM, it runs on a 60 Hz supply and is housed in a Totally Enclosed Fan-Cooled (TEFC) enclosure that protects internal components from dust, moisture, and debris. The 184 frame with C-Face mount provides a standardized bolt pattern for direct coupling to pumps, compressors, fans, and other driven equipment. Double-shielded ball bearings support the load at both ends, and Class F insulation handles elevated operating temperatures common in demanding service environments. Full load amperage ranges from 14.2 to 12.8 amps on high voltage and 6.4 amps on low voltage.

This motor is suited for general equipment applications in light industrial, commercial HVAC, and process settings. The C-Face mount makes it straightforward to install on inline pumps, gearboxes, and close-coupled machinery where shaft alignment is critical. The TEFC enclosure style means it can be placed in areas with airborne contaminants or occasional washdown exposure without additional motor protection enclosures. Licensed electricians and mechanical contractors typically handle installation and commissioning on three-phase equipment of this frame size.

Key Features

• 184 frame C-Face mount for standardized coupling to pumps and gearboxes
• Double-shielded ball bearings for reliable load handling and reduced maintenance
• Class F insulation rating for extended thermal tolerance
• Rolled steel frame construction for durability in industrial environments

Compatibility

Designed as an OEM-style replacement or direct-drive substitute for 5 HP, 184 frame, C-Face TEFC three-phase AC motor applications in general equipment service.

Installation Notes

Three-phase motor installation must be performed by a qualified electrician in accordance with NEC Article 430 and applicable local codes. Disconnect and lock out all power sources before removing the existing motor or making any wiring connections. Verify supply voltage and phase rotation match the motor nameplate before energizing. Ensure the mounting surface and coupling or sheave are properly aligned to avoid premature bearing wear.
