Air Compressor Motor 5HP Electric Motor 1750 RPM
Brand: GCCSJ. This 5HP, 184T TEFC motor is designed for air compressors and continuous use. It features a rolled steel shell for durability, IP54 protection, and a fully enclosed fan to maintain cooler operation during long runs. It supports 208-230V operation and CW/CCW rotation for flexible mounting. Shaft diameter is 1-1/8″, with a 2.75″ shaft length. Suitable for demanding environments with moisture and dust exposure, thanks to robust sealing and thermal efficiency.
Air Compressor Motor 5HP, Industry AC Motor 184T Frame
Brand: Cuilvu. This 5HP motor is built with a 184T frame and TEFC enclosure, IP54, and a protective open design. It runs at 1750 RPM and supports CW/CCW rotation. It features a compact structure, high heat dissipation through multiple radiators, and a large end fan for cooler operation in challenging environments. This makes it suitable for consistent air compression tasks with reliable duty cycles.
5HP Air Compressor Motor, 1750 RPM 208-230V
Brand: FAHKNS. This 5HP motor delivers 1750 RPM with TEFC enclosure, IP54, and a rolled steel housing for heat dissipation and long service life. It includes a large fan for cooling during extended runs and is designed for farm-duty and general air compressor applications. Shaft diameter is 1-1/8″ with a 2-3/4″ shaft length, CW/CCW operation, and 208-230V compatibility.
Electric Motor, 1.5HP Air Compressor Motor, 1750RPM
Brand: GCCSJ. While not a 5HP unit, this 1.5HP motor operates at 1750 RPM and is suitable for lighter air compressor setups or as a supplementary drive. It features a 56C frame, 115/230V dual voltage, and CW/CCW rotation. The motor includes a fully enclosed fan for enhanced cooling in wet and dusty conditions, and a rolled steel housing for durability.
VEVOR 5HP Air Compressor Motor, 230V
Brand: VEVOR. This 5HP, 230V motor is rated at 56 frame with 1750 RPM in common 2-pole design. It uses a 7/8″ keyed shaft and provides an open drip-proof (ODP) enclosure, designed for clean, dry environments. It offers solid heat dissipation and a robust rolled steel housing, appropriate for consistent compressor operation with a long service life.
VEVOR 5HP SPL Air Compressor Motor
Brand: VEVOR. Although this model operates at 3450 RPM (SPL), it is included for comparative context against 1750 RPM units. It is a single-phase motor with 230V supply, 17.6A current draw, and a 56 frame with a 5/8″ keyed shaft. It features an open drip-proof design and is intended for clean, dry environments. Rotation is typically CCW by factory setting, with CW/CCW adjustability on some variants.
Buying Guide: Key Considerations for 5 HP Motors and 1750 RPM
When selecting a 5 HP air compressor motor around 1750 RPM, consider these factors to ensure compatibility, efficiency, and longevity:
- Power and speed: Confirm motor is rated at 5 HP and designed for 1750 RPM (2-pole) for typical air compressor loads. If a unit lists 3450 RPM, it is not a direct 1750 RPM match and will affect torque and compression characteristics.
- Frame size: Most 5 HP 1750 RPM motors use 184T or 56 frame variants. Match the replacement to the existing mounting footprint and shaft alignment.
- Enclosure and protection: TEFC (Totally Enclosed Fan-C cooled) is common for dry environments; IP ratings (e.g., IP54) indicate moisture and dust protection. Open Drip-Proof (ODP) is suitable for cleaner, drier spaces but provides less protection against moisture.
- Voltage and wiring: Ensure voltage compatibility with your system (commonly 208-230V or 115/230V dual voltage). Check motor rotation direction CW vs CCW to match pulley and belt routing.
- Shaft and coupling: Verify shaft diameter and length for shaft couplings, belts, and pulleys. A 1-1/8″ diameter is common for 5 HP 184T frames; confirm keyway type and shaft length requirements (e.g., 2.75″ or 2.25″).
- Cooling and duty: Fully enclosed fans and rolled steel housings aid thermal management during long runs. Consider a motor with enhanced cooling or additional radiators for high-duty environments.
- Certifications and safety: Look for CSA/UL certifications, insulation class, and S1 continuous service ratings for farm or commercial duty motors.
- Installation considerations: Check mounting orientation, wire sizing, and protective devices (fuses/ breakers) appropriate for 28–29A running current at 208–230V.
These factors help balance initial cost, energy efficiency, and maintenance needs. For installation, consult a trained technician to ensure proper shaft alignment, wiring, and ventilation to maximize motor life and compressor performance.
