Us Motors WDS1E2AC 1 Hp Three Phase Ac Motor Tefc 143TC

Product Description

The US MOTORS WDS1E2AC is a three-phase, energy-efficient AC motor built for continuous-duty industrial and commercial applications. Rated at 1 horsepower and 1750 RPM, it operates on 208 to 230 volts or 460 volts at 60 Hz, making it adaptable to a wide range of facility power configurations. The motor ships in a TEFC (Totally Enclosed Fan-Cooled) enclosure with a steel frame, providing protection against dust and moisture ingress in demanding environments. Full load efficiency is rated at 85.50 percent with a service factor of 1.15, giving the unit a usable overload margin above its nameplate rating. Licensed electricians and millwrights are the typical installers for this class of motor.

This motor is suited for light-duty mechanical drive applications in commercial HVAC equipment, pumps, fans, compressors, and conveyor systems where a 143TC rigid-mount footprint is required. The reversible rotation makes it adaptable during commissioning without additional hardware. At 39 pounds, it is a manageable single-person lift for bench mounting or direct-drive installations. The Class F insulation and 40 degrees F ambient operating rating support reliable performance in both indoor mechanical rooms and protected outdoor enclosures.

Key Features

• Dual-voltage operation: 208 to 230 volts or 460 volts, 60 Hz
• TEFC steel enclosure resists dust and moisture without external ventilation requirements
• 143TC rigid-mount frame provides a standardized footprint for direct replacement installations
• Reversible rotation configurable at installation without modification
• Class F insulation with 1.15 service factor for sustained overload tolerance

Compatibility

Designed as an OEM-style replacement or new-installation motor for three-phase mechanical drive applications requiring a 143TC rigid-mount frame at 1 HP and 1750 RPM.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for three-phase motor circuits, including proper overcurrent protection and disconnect means. Disconnect and lockout-tagout all power sources before handling wiring or mounting hardware. Verify supply voltage matches the motor nameplate connection configuration before energizing. Do not operate the motor without proper coupling alignment, as shaft misalignment will accelerate bearing wear and reduce service life.
