5HP Electric Motor for Air Compressors by FAHKNS
The FAHKNS 5HP Electric Motor is a single-phase, 208-230V model with a 1750 RPM rating and a robust 184T frame. It features TEFC (Totally Enclosed Fan C cooled) construction and IP54 protection, making it suitable for slightly dusty or damp environments typical of shop floors. The motor includes a 1-1/8″ shaft and a 2.75″ shaft length, with a rolled steel housing for durability. Rotation is CW/CCW, allowing flexible belt or pulley alignment to suit your air compressor or ancillary equipment. This farm-duty class motor is CSA certified for safety and long service life.
VEVOR 5HP SPL Air Compressor Motor, 56 Frame
This VEVOR SPL motor delivers 5 HP at 3450 RPM with a 56-frame footprint, designed for single-phase 230V systems. It draws around 17.6A at full load, making it a relatively efficient choice for air compressors that require quick starts and high RPM. The 5/8″ keyed shaft provides reliable coupling with belts or pulleys, and the shaft length is 1.88″. The motor is open drip-proof (ODP) and best used in clean, dry environments where heat dissipation is straightforward. Its steel construction supports long service life and straightforward maintenance.
VEVOR 5HP Air Compressor Motor, 56 Frame, 230V
This VEVOR model provides 5 HP at 3450 RPM within a 56HZ frame, suitable for parallel setups with typical air compressors. It uses a 7/8″ keyed shaft and a 2.25″ shaft length. The design operates on 230V single-phase power with a listed full-load current of 25A. The motor is open drip-proof and built from high-quality steel to extend service life. Like other open-frame designs, ensure installation in a dust-free, dry environment where cooling is efficient to maintain performance during continuous operation.
5HP General Purpose Three Phase Motor (Clone Mention)
Note: This entry is included to illustrate cross-compatibility considerations and is a reference for context. The motor listed here is a three-phase option with a 184T frame, 1-1/8″ shaft, and a cast iron shell, suitable for higher-duty applications. For single-phase configurations, confirm that the application matches the motor’s electrical specification and drive compatibility, as single-phase installations may require soft-start or capacitor assistance in some setups.
5 HP Farm Duty Single Phase Electric Motor
This Worldwide Electric 5 HP motor is designed for farm-duty single-phase use, rated for 208-230V operation with a 184T frame and 1800 RPM. The motor is TEFC (Totally Enclosed Fan Cooled) and IP55 rated, providing protection against dust and moisture typical in agricultural settings. The design emphasizes durability and steady performance under continuous operation, with a robust rolled steel shell and a safe, durable build for long-term service life.
GCCSJ 5HP Air Compressor Motor, 1750 RPM
Note: This entry repeats GCCSJ’s 5HP options to reflect the variety of 1750 RPM, 208-230V single-phase motors with TEFC housings and rolled steel shells. It features a 1-1/8″ shaft and a 2.75″ shaft length, with CW/CCW rotation support. The 60 Hz, 208-230V operation and IP54 protection make it suitable for duty cycles common to air compressors, with emphasis on heat dissipation in continuous run conditions.
Buying Guide: Key Considerations for 5 HP Single-Phase Motors
- Electrical specifications: Confirm voltage (208-230V), single-phase vs. three-phase requirements, and current draw at full load to match your power source and circuit protection.
- Frame and shaft details: Ensure frame compatibility with your equipment mounting and that shaft diameter and length fit pulleys, couplings, and sprockets.
- Duty cycle and cooling: TEFC housings and integral cooling (F or CW/CCW rotation) influence performance in continuous or heavy-use applications; consider IP rating for dusty or damp environments.
- Rotation direction: CW vs CCW orientation can affect belt drive layouts; verify if you need the opposite rotation and whether the motor supports reversing rotation without interior reconfiguration.
- Durability and safety: Look for rolled steel or cast iron shells, CSA or other safety certifications, and weather-related protections like IP ratings for farm or shop use.
- Maintenance and service life: Consider open-drip vs. TEFC, heat dissipation design, and availability of replacement parts or compatible accessories.
- Environment and placement: Clean and dry environments maximize motor life; use vibration isolation, proper mounting, and enclosure if exposure to dust or moisture is expected.
