VEVOR 7.5HP Air Compressor Motor: 230V, 184T frame and specs

This VEVOR motor is a 7.5HP single-phase electric motor intended for driving air compressors. It is a replacement or upgrade part: you mount it on a compressor pump, connect it to a suitable 230V supply, and it supplies the rotation that drives the pump. Getting a good match comes down to reading the frame, shaft and electrical specs carefully.

Power and speed

VEVOR lists 7.5HP at 3450 RPM on 230V, 60Hz, single phase. A speed of 3450 RPM is typical of two-pole motors on 60Hz supplies, where the rotor turns slightly slower than the 3600 RPM synchronous speed. The service factor is 1.0, which means the motor is rated for its nameplate load with no built-in overload margin, so it shouldn't be sized to run beyond 7.5HP.

Electrical demand

The full-load current is 31.6 A. That is a substantial draw, and VEVOR notes that the customer's circuit breaker should be 60 amps. A motor this size needs wiring, a breaker and a starter or control suited to the load, so have the installation checked against the manual and local electrical codes, and consider an electrician.

What a 184T frame means

The frame designation tells you the mounting dimensions. A 184T frame is a standard NEMA size with fixed foot-hole spacing and shaft height, so a motor in the same frame should bolt to the same mounting base. Here the shaft is 1-1/8 in in diameter with a keyway of 0.25 in, and a shaft length of 2.75 in. Check these against your pump's pulley or coupling.

Rotation direction

The motor is reversible between clockwise and counter-clockwise rotation, with CCW as the factory setting. (The listing prints the direction as "CCW/CCW", so confirm the exact options in the manual.) Many compressor pumps run in one direction only, often marked by an arrow, so check before powering up.

Enclosure and environment

The enclosure is open drip-proof. This design lets air pass through for cooling while shielding against drips from above. VEVOR suggests using it in clean, dry environments. Dusty or damp workshops may call for a different enclosure. The steel frame is described as sturdy and tested with CSA certification.

Who it suits

It suits owners of stationary air compressors needing a replacement motor, and workshops building or restoring a compressor around a 7.5HP motor.

What to check before you buy

• Frame and shaft: confirm 184T, the 1-1/8 in shaft and keyway fit your pump or pulley.
• Supply: you need 230V single-phase and a breaker rated as the listing states.
• Direction: confirm the pump's required rotation and how to set the motor.
• Environment: keep it clean and dry; allow airflow around it.
• Controls: check what starter, pressure switch or wiring you will need.
• Installation: follow the manual and local electrical codes.

The short version

• 7.5HP single-phase motor for air compressors, 230V 60Hz, 3450 RPM.
• Full load 31.6 A; the listing advises a 60 A breaker.
• 184T frame, 1-1/8 in keyed shaft, 2.75 in shaft length.
• Reversible rotation, open drip-proof enclosure.
• Listed as CSA tested; steel frame.
