GCCSJ’s 5 HP motor is built around a 184T frame and 208–230V operation at 1750 RPM. It features TEFC enclosure with IP54 protection, and a 1-1/8″ shaft diameter with a 2.75″ shaft length. The rolled steel housing provides strength and durability, while the large cooling fan helps maintain performance during long cycles. CW/CCW rotation ensures flexible pulley or coupling alignment for air compressors or industrial fans.
5 HP Farm Duty Single Phase Electric Motor
Worldwide Electric’s 5 HP motor is designed for farm-duty single-phase applications with a 184T frame and TEFC enclosure. It operates on 208/230V and is rated for single-phase operation with good protection (IP55) and resilience for outdoor or barn environments. While the listed rotation is CW/CCW, these motors are commonly used with pump and conveyor setups where steady torque and reliable cooling are beneficial. Shaft dimensions align with standard pulley and coupler fittings for 1-1/8″ shafts.
5HP Air Compressor Motor, 1750 RPM — FAHKNS
This 5 HP motor combines a farm-duty design with air compressor suitability, offering 208–230V operation at 1750 RPM, 28.5–27.0A current, and a 1-1/8″ shaft diameter. The 184T frame and TEFC enclosure with IP54 protection deliver durable performance in challenging environments. A large cooling fan helps dissipate heat, supporting longer run times and improved efficiency, with CW/CCW rotation for installation flexibility.
Buying Guide: Key Purchase Considerations
To choose the best 5 HP single-phase motor around 1750 RPM, consider these factors:
- Voltage and frequency: Most options run on 208–230V at 60 Hz. Verify local electrical supply and compatibility with existing equipment.
- Frame and enclosure: A standard 184T frame with TEFC housing is common for air compressors and farm-duty loads, offering durable protection in dusty or damp environments.
- Rotational direction: CW/CCW capability provides installation flexibility; ensure mounting orientation aligns with pulley or belt drives.
- Cooling and protection: Fully Enclosed Fans and IP54 ratings help maintain performance in harsh settings and extend motor life.
- Shaft and mounting: 1-1/8″ shaft diameter with a shielded length around 2.75″ fits most intermediate pulleys and couplings; check mounting pattern and shaft keys if needed.
- Certification and safety: CSA or equivalent farm-duty certifications indicate suitability for tough, long-running use in agricultural or workshop environments.
- Efficiency and heat management: Larger cooling fans and robust housings reduce operating temperatures, potentially lowering energy costs over time.
Compared options cover similar performance metrics, with variations in enclosure protection, heat dissipation, and frame-specific features. When selecting, match motor specs to the intended load (air compressors vs. pumps), consider environmental exposure, and ensure available space allows for airflow and service access. Always verify shaft dimensions, mounting clearance, and compatible accessories (pulleys, couplers, and shaft keys) for a smooth installation.
