Us Motors WDS34S2AHC 3/4 Hp Tefc Three Phase Ac Motor

Product Description

The US MOTORS WDS34S2AHC is a three-phase, energy-efficient AC motor built for continuous-duty industrial and commercial applications. Rated at 3/4 horsepower and 1750 RPM nameplate speed, it operates on 208 to 230 volts or 460 volts at 60 Hz, making it compatible with both single-voltage and dual-voltage three-phase supplies. The motor features a Totally Enclosed Fan-Cooled (TEFC) enclosure with a rigid mount configuration and a 56HC frame. Ball bearings, Class F insulation, and a 1.15 service factor contribute to a durable, thermally capable design suited for demanding environments. Full load efficiency is rated at 82.50 percent.

This motor is appropriate for light-duty mechanical loads in commercial HVAC equipment, pumps, fans, compressors, and general industrial machinery requiring a three-phase power source. The 56HC frame and rigid mount style make it a direct-fit option for equipment designed around NEMA 56HC frame motors. The reversible rotation feature gives installers flexibility during initial setup or when replacing motors in applications with specific shaft-direction requirements. It is intended for installation by licensed electricians or qualified mechanical contractors familiar with three-phase motor wiring and NEC compliance requirements.

Key Features

• 3/4 HP output at 1750 RPM nameplate speed
• Dual-voltage operation: 208 to 230 volts or 460 volts, 60 Hz, three-phase
• TEFC enclosure protects against dust and moisture in non-washdown environments
• 56HC rigid mount frame for direct OEM-style replacement fitment
• Class F insulation with 1.15 service factor for thermal headroom under load
• Reversible motor rotation for flexible installation orientation
• Ball bearing construction for reliable performance and reduced maintenance

Compatibility

Designed as an OEM-style replacement for three-phase NEMA 56HC frame rigid-mount motors in commercial and industrial equipment requiring a 3/4 HP, 1750 RPM TEFC motor. Also referenced under Dayton part number 6ML24.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 430 governing motor branch circuits and overcurrent protection. Disconnect and lockout all power at the panel before removing the existing motor or making any electrical connections. Verify the supply voltage matches the motor nameplate before wiring, as incorrect voltage selection on a dual-voltage motor can cause immediate damage. Confirm shaft rotation direction under no-load conditions before coupling to driven equipment.
