VEVOR 7.5HP Air Compressor Motor
The VEVOR 7.5HP Air Compressor Motor delivers high power in a robust 184T frame and 230V single-phase design. It provides 3450 RPM and a 1-1/8″ diameter key shaft, with a 2.75″ shaft length and a 0.25″ keyway. The unit is built for durable operation in demanding air compression tasks, featuring a large-capacity fan and open drip-proof construction suitable for clean environments. Reversible rotation (CCW/CCW) enhances wiring flexibility and maintenance planning, helping installers optimize layout and reduce downtime.
VEVOR 5HP SPL Air Compressor Motor
This 5HP SPL motor runs at 3450 RPM with a 56-frame footprint and a 5/8″ keyed shaft. It operates on 230V single-phase power with a full-load current around 17.6A and is designed to tolerate industrial duty. The motor employs an open drip-proof construction to handle dry environments and uses high-quality steel to extend service life. Its reversible rotation (CCW/CCW) supports adaptable wiring configurations for various compressor setups.
Air Compressor Motor 5HP (Cuilvu)
The 5HP Cuilvu motor features a compact industry-grade 184T frame with TEFC (Totally Enclosed Fan C cooled) design, suitable for CW/CCW rotation. Rated for 208-230V operation, it includes a 1-1/8″ shaft diameter and a 2.75″ shaft length. The enclosure supports heat dissipation through its dual-radiator setup, helping maintain performance during extended runs. A large end-mounted fan improves cooling under dusty or wet conditions, contributing to longer motor life and reduced energy-related costs.
Worldwide Electric 5HP Farm Duty Motor
The Worldwide Electric 5HP Farm Duty motor is designed for single-phase operation with TEFC (Totally Enclosed, Fan Cooled) protection. The 184T frame supports 1-1/8″ keyed shafts and a sturdy design intended for agricultural and farm-use equipment. Its IP rating and enclosure type provide reliable performance in variable environments, while the TEFC construction minimizes maintenance needs and enhances longevity under continuous operation.
mitoharet 1 HP Electric Motor
The mitoharet 1 HP motor provides a compact option for lighter-duty tasks. It runs at up to 1750 RPM and is configurable for 115V or 230V operation. This single-phase motor features a steel shell for reliable protection and a large cooling fan to dissipate heat during extended usage. Reversible rotation (CW/CCW) adds versatility for different equipment layouts and drives, making it suitable for agricultural or small industrial applications where space is at a premium.
Buying Guide: Key Purchase Considerations
- Horsepower and frame compatibility: Match the motor’s horsepower and frame (56 or 184T, etc.) to your equipment’s mounting pattern and load requirements. Higher HP motors deliver more torque and sustained performance for heavy-duty applications.
- Voltage and single-phase vs. three-phase: Most consumer-grade air compressor motors run on single-phase 115/230V. Confirm your power supply and wiring capabilities before purchasing.
- Rotation direction and wiring: Reversible (CW/CCW) rotation can simplify installation and future maintenance. Ensure wiring diagrams align with your equipment’s drive pulley or shaft configuration.
- Enclosure and cooling: TEFC or open drip-proof designs affect durability in dusty, oily, or humid environments. Consider the environment and required cooling for continuous operation.
- Durability and protection: Look for high-quality steel construction, robust shafting, and protective features like large cooling fans. For outdoor or farm-duty use, enclosure type and IP rating matter.
- Maintenance and life cycle: Motors with efficient heat dissipation and durable bearings reduce maintenance frequency and total cost of ownership.
- Installation and compatibility: Check shaft diameter, keyway size, and length to ensure compatibility with existing pulleys, sheaves, or couplings.
