It runs at 1725 RPM nameplate speed on a 56HZ frame with a rigid mount configuration and an OPAO (open protected air over) enclosure. The motor accepts multiple voltage inputs — 208 to 230 volts, 460 volts, 190 volts, and 380 volts — making it adaptable to a range of electrical service configurations. A full-load efficiency rating of 85.80 percent and a service factor of 1.15 give it reliable headroom under variable load conditions. Ball bearings and Class B insulation support sustained operation in typical air-over environments. Licensed HVAC technicians and motor service professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis motor is suited for forced-air HVAC equipment where three-phase power is available. The OPAO enclosure style is intended for installations where the motor is cooled by the airstream passing over it, such as in direct-drive or belt-drive fan and blower assemblies. The reversible rotation direction adds flexibility during installation or system replacement. It operates on both 60 Hz and 50 Hz power, making it usable in North American and select international applications. The rigid mount style requires a solid, flat mounting surface appropriate to the 56HZ frame footprint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2 HP output at 1725 RPM nameplate speed on a 56HZ frame\u003c\/li\u003e\n  \u003cli\u003eMulti-voltage input: 208 to 230 volts, 460 volts, 190 volts, and 380 volts\u003c\/li\u003e\n  \u003cli\u003eDual frequency rated: 60 Hz and 50 Hz\u003c\/li\u003e\n  \u003cli\u003eOPAO enclosure for air-over cooling in blower and fan assemblies\u003c\/li\u003e\n  \u003cli\u003eReversible motor rotation for flexible installation orientation\u003c\/li\u003e\n  \u003cli\u003eAutomatic thermal protection with Class B insulation and 40 degrees F ambient operating rating\u003c\/li\u003e\n  \u003cli\u003eService factor of 1.15 provides load overhead above nameplate rating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade motor for three-phase HVAC fan and blower applications requiring a 2 HP, 56HZ frame, rigid-mount motor with an OPAO enclosure.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements for motor branch circuits. Disconnect and lock out all power to the equipment before removing the existing motor or making any wiring connections. Confirm that the supply voltage and phase configuration match one of the motor nameplate ratings before energizing. The 5\/8-inch shaft diameter should be verified against the driven component coupling or pulley bore before mounting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 2 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNameplate Speed\u003c\/strong\u003e: 1725 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 208 to 230 \/ 460 \/ 190 \/ 380 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz \/ 50 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Load Efficiency\u003c\/strong\u003e: 85.80 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eService Factor\u003c\/strong\u003e: 1.15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrame Size\u003c\/strong\u003e: 56HZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Type\u003c\/strong\u003e: OPAO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Style\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Class\u003c\/strong\u003e: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermal Protection\u003c\/strong\u003e: Auto\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Rotation\u003c\/strong\u003e: Reversible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Speeds\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter x Length\u003c\/strong\u003e: 5\/8 inches x 1-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmbient Operating Temperature\u003c\/strong\u003e: 40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 29 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: HVAC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: US MOTORS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1815\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"US MOTORS","offers":[{"title":"Default Title","offer_id":51541283471666,"sku":"1815","price":454.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61f59be07d2eb5af9cf80bf53354ca77_785af36b-687e-4e73-8921-b2850be86bf4.jpg?v=1785871365","url":"https:\/\/voomisupply.com\/products\/us-motors-1815-three-phase-ac-motor-2-hp-1725-rpm","provider":"Voomi Supply","version":"1.0","type":"link"}
