Rated at 3\/4 horsepower and 3450 RPM, this motor runs on a 60 Hz supply and fits the NEMA 56 frame standard. The open drip-proof (ODP) enclosure allows airflow through the motor for cooling while protecting against incidental liquid contact from above. Ball bearings support the 5\/8-inch diameter shaft, and Class B insulation handles normal operating heat loads. A service factor of 1.25 means the motor can handle brief overloads above its nameplate rating. Licensed HVAC and mechanical technicians handle most installations of this motor class.\u003c\/p\u003e\u003cp\u003eThis motor is suited for residential and light commercial HVAC equipment, compressors, fans, pumps, and general-purpose belt-drive or direct-drive applications that call for a NEMA 56 frame rigid-mount single-phase motor. The reversible rotation makes it adaptable to a range of equipment configurations without requiring a different part number. The ODP enclosure is appropriate for indoor installations in clean to moderately dusty environments where the motor is protected from direct water spray. Technicians replacing a failed PSC motor in an air handler, condenser, or similar unit will find this a direct-fit candidate for NEMA 56 frame rigid-mount positions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 HP single-phase PSC motor rated at 3450 RPM for high-speed direct-drive applications\u003c\/li\u003e\n\u003cli\u003eNEMA 56 frame with rigid mount for straightforward OEM-style replacement\u003c\/li\u003e\n\u003cli\u003eReversible rotation field-configurable without additional hardware\u003c\/li\u003e\n\u003cli\u003eBall bearing construction for long service life under continuous-duty loads\u003c\/li\u003e\n\u003cli\u003e1.25 service factor allows brief operation above nameplate load\u003c\/li\u003e\n\u003cli\u003eClass B insulation rated for ambient operating temperatures starting at 40 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for single-phase PSC motors using a NEMA 56 frame rigid-mount configuration.

Disconnect and lock out all power to the unit before removing the failed motor or making any wiring connections. Verify supply voltage, capacitor rating, and rotation direction before energizing the replacement motor. Do not operate the motor without confirming the run capacitor is correctly sized for the PSC circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: Single Phase Permanent Split Capacitor (PSC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 3\/4 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNameplate RPM\u003c\/strong\u003e: 3450\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size\u003c\/strong\u003e: NEMA 56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Style\u003c\/strong\u003e: ODP (Open Drip-Proof)\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\u003eShaft Diameter x Length\u003c\/strong\u003e: 5\/8 inches x 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Load Efficiency\u003c\/strong\u003e: 65.40%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Factor\u003c\/strong\u003e: 1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Rotation\u003c\/strong\u003e: Reversible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Protection\u003c\/strong\u003e: None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Speeds\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmbient Operating Temperature\u003c\/strong\u003e: 40 degrees F minimum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 27 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: D34C1J\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"US MOTORS","offers":[{"title":"Default Title","offer_id":51543545413938,"sku":"D34C1J","price":300.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd79933a3e4cce9f4fb8c94f2cc754b7_d092d1af-f052-4461-b357-a725ff4b4ab6.jpg?v=1785920236","url":"https:\/\/voomisupply.com\/products\/us-motors-d34c1j-psc-ac-motor-3-4-hp-3450-rpm-56-frame","provider":"Voomi Supply","version":"1.0","type":"link"}
