VEVOR 5HP 230V Air Compressor Motor: features, specs and who it suits

This VEVOR 5HP electric motor is a replacement or build-your-own power unit for air compressors. It runs on single-phase 230V power at 3450RPM, and it is built around a standard frame and shaft so it can be matched to a compressor pump. Here is what the listed specs mean and what to confirm before fitting one.

What the headline numbers mean

5HP is the motor's rated output, roughly 3.7kW. 3450RPM is the shaft speed, typical of a two-pole motor on a 60Hz supply, and a common speed for direct-drive and belt-drive compressor pumps. Single phase, 230V means it is intended for the kind of supply found in many workshops and garages rather than a three-phase industrial feed.

VEVOR lists the full load current as 25 amps. This is the current the motor draws at its rated load, and it is the figure that matters for wiring and protection.

Frame, shaft and fitting

The motor uses a 56HZ frame with a 7/8-inch keyed shaft, 2.25 inches long. The frame size sets the mounting footprint and shaft height, while the keyed shaft holds a pulley or coupling so it can't slip. These are the details to compare against the compressor pump and pulley you intend to use. A mismatch in shaft diameter or length typically means a different pulley, bushing or mounting plate.

Reversible rotation

The motor can turn either clockwise or counter-clockwise. The factory setting is counter-clockwise, and VEVOR says the reversible design makes wiring easier. This matters because compressor pumps usually have a required direction of rotation, often marked on the pump or flywheel. Check the pump's direction and the motor's wiring instructions before powering up.

Open drip-proof housing

The enclosure is open drip-proof, which VEVOR suggests using in clean, dry environments. An open design lets air flow through for cooling, but it also means dust, moisture and debris can get in more easily than with a fully enclosed motor. A sheltered spot in a workshop is the usual home for this type.

Construction and certification

VEVOR describes a rolled steel shell with fast heat dissipation, and says the motor has been tested with CSA certification. The listed dimensions are 14.8 x 10.4 x 11.0 inches (about 38 x 26 x 28 cm), and it weighs 40.8 lb (about 18.5 kg), so it needs a solid mounting base.

Who it suits

It suits people replacing a worn-out compressor motor, builders putting together a workshop air system from separate parts, and anyone needing a 5HP single-phase unit with a 56 frame. It is a motor only, so the compressor pump, tank, pressure switch and controls come from elsewhere.

What to check before you buy

• Circuit: the listing notes that the customer-supplied circuit breaker should be 60 amps. Confirm your supply can support this, and have wiring done in line with local electrical codes and the manual.
• Shaft and frame: compare the 7/8-inch keyed shaft, 2.25-inch length and 56HZ frame with your pump and pulley.
• Rotation: confirm the direction your pump needs and how to set it.
• Environment: make sure the location is clean and dry.
• Weight and mounting: plan a rigid base for a motor of about 41 lb.
• Controls: check what starter, switch or pressure control you'll need, as none is described in the listing.

The short version

• VEVOR 5HP single-phase electric motor, 230V, 3450RPM, 25A full load.
• 56HZ frame, 7/8-inch keyed shaft, 2.25 inches long.
• Reversible rotation, factory set to counter-clockwise.
• Open drip-proof design for clean, dry settings; CSA-tested according to the brand.
• Needs a 60-amp breaker, per the listing; follow local codes and the manual.
