Us Motors D1S2AHC 1 Hp Three Phase Ac Motor 56C Odp

Product Description

The US MOTORS D1S2AHC is a three-phase, energy-efficient AC motor designed for general-purpose industrial and commercial applications. Rated at 1 horsepower and 1725 RPM at 60 Hz, it operates in an open drip-proof (ODP) enclosure with a 56C frame and C-Face mount. The steel frame construction and ball bearing design deliver reliable, low-maintenance performance across a wide range of driven loads. Full load efficiency is rated at 82.40 percent with a service factor of 1.15, allowing short-term overloading without damage. The motor is reversible in rotation, adding installation flexibility. Licensed HVAC technicians, millwrights, and general maintenance electricians are the typical installers.

The D1S2AHC is suited for general-purpose applications in light industrial, commercial HVAC, and process equipment settings. The C-Face mount makes it a direct fit for pumps, blowers, compressors, and gearboxes that require close-coupled mounting. The ODP enclosure is appropriate for indoor installations or protected outdoor locations where dripping or splashing water is not a concern. Single-speed operation at 1725 RPM and a 60 Hz rated frequency make it compatible with standard North American power systems. The 5/8-inch shaft diameter suits a wide range of standard couplings and drive components.

Installation Notes

Installation should be performed by a licensed electrician or qualified maintenance technician in accordance with NEC requirements for motor branch circuits, including proper overload protection sized to the full load amperage. Disconnect and lock out all power before mounting or making electrical connections. Verify shaft alignment and coupling fit before energizing. The ODP enclosure should not be installed in wet, washdown, or highly contaminated environments without additional protection.
