VEVOR 5HP Air Compressor Electric Motor
VEVOR’s 5HP motor is a single-phase unit rated for 230V with a full-load current around 25A. It runs at 3450 RPM on a 56HZ frame and uses a 7/8″ keyed shaft, with a 2.25″ shaft length. The open drip-proof (ODP) design is best suited for clean, dry environments. Constructed from high-quality steel, the motor is built for durability and longer service life. CW/CCW rotation allows flexible wiring and compatibility with various compressor models.
5 HP Air Compressor Electric Motor (GCCSJ)
This GCCSJ motor operates at 230V, 3450 RPM, with a 7/8″ shaft and 2.25″ shaft length. It uses a 56HZ frame and is designed with an open drip-proof enclosure to suit clean, dry environments. The motor offers CCW rotation by default and provides a compact, efficient design intended for reliable compressor performance, with heat-dissipating radiators contributing to sustainable operation.
VEVOR 5HP SPL Air Compressor Electric Motor
This SPL (single-pole) motor delivers 3450 RPM with a 56 frame and 5/8″ keyed shaft. Shaft length is 1.88″. It includes dual CW/CCW rotation and is designed for clean, dry environments. The open drip-proof construction helps with heat dissipation, extending motor life while maintaining efficient operation for air compressors.
Air Compressor Motor 5HP (GCCSJ) 1750 RPM
This motor runs at 1750 RPM, making it suitable for lower-speed compressors and heavy-duty TEFC or open frame configurations. It operates at 208-230V with amperage around 27-28A and features a 1-1/8″ shaft diameter and 2.75″ shaft length. The rolled steel shell and fully enclosed fan help maintain operation in challenging environments while offering solid durability for long-term use.
Vahaha 5HP Electric Motor for Air Compressors
The Vahaha motor provides a 5HP SPL configuration at 3450 RPM, 230V, and 22A full-load current. It uses a 7/8″ keyed shaft with a 2.25″ shaft length and CCW rotation by default. The open drip-proof design suits clean, dry environments, while the steel shell and mounting bracket add durability and stability for continuous compressor operation.
Buying Guide: Key Purchase Considerations
- Motor type and environment: Open drip-proof (ODP) is common for clean, dry spaces, while TEFC models offer better sealing in dusty or humid conditions. Choose based on your workshop environment.
- Voltage and phase: All listed options are 230V single-phase, but some variants may support 208-230V ranges. Confirm voltage compatibility with your equipment and power supply.
- Rotation direction: Most units ship CCW; select CW or CCW options if your pump or belt arrangement requires a specific rotation. Shaft length and diameter must align with your mounting and pulley setup.
- Shaft specifications: Keyed shaft size and length (e.g., 7/8″ x 2.25″) affect pulley compatibility and mounting hardware. Ensure your drive components match.
- Frame size and RPM: A 56HZ vs. 60Hz frame can influence rotation speed and heat management. Higher RPMs provide faster compressor cycles but may demand better cooling and wiring.
- Durability and materials: Steel housings, robust bearings, and effective heat dissipation extend motor life. Look for enclosed fans and protective features for longer service intervals.
- Maintenance and service life: Open architecture may require more frequent cleaning in dusty environments; consider enclosed designs for harsher settings.
- Warranty and support: Check manufacturer and seller warranties, as well as the availability of spare parts like capacitors and bearings for future service.
- Compatibility: Verify shaft diameter, pulley sizes, and mounting footprint to ensure smooth integration with your existing compressor unit.
