The JIAXINPRO 2HP Air Compressor Motor is a dual-voltage choice for a 2 HP compressor that can use either 115V or 230V. It runs at 3450 RPM and has CW/CCW reversible rotation.
The 56 frame and 5/8 in keyed shaft are paired with a 1.88 in shaft length. Check those measurements against the old motor, then follow the wiring diagram on the motor label for the selected voltage.
This option suits a replacement where the 2 HP rating and dimensions match. The motor's 115/230V range does not remove the need to confirm the circuit and wiring setup.
What should you match before buying a 240V compressor motor?
Match the motor's voltage, horsepower, frame, shaft and rotation to the compressor's requirements before placing an order. A mismatch in any one of these can prevent installation or create an unsafe setup.
Start with the motor plate or manual. Look for voltage, phase, horsepower, RPM, frame size, full-load amps and rotation direction.
Then measure the shaft diameter and length, and compare the keyway and pulley position. Frame labels such as 56 or 56HZ help identify a mounting size, but they do not replace checking the actual mounting and alignment.
If you need a cord for your installation, see the best 240V air compressor power cord options. The cord and circuit must suit the motor's electrical requirements.
Does 240V mean every motor here works on a 240V circuit?
No. The options have different stated voltage ranges, and wiring may need to change between configurations.
Check the motor's label and wiring diagram for the exact setup.
The EMZ motor is labeled 120/240V and defaults to 120V wiring. The JIAXINPRO supports 115/230V, while the VEVOR 5 HP and 3.7 HP options are labeled 230V.
Baldor specifies 208–230V, including use at 208V. These ranges are not interchangeable without checking your supply and compressor requirements.
How do frame, shaft and rotation affect replacement fit?
Frame, shaft and rotation determine whether a motor can mount and drive the compressor correctly. Compare all three with the original motor or the compressor manual.
The picks include 56 and 56HZ frames, 5/8 in and 7/8 in keyed shafts, and shaft lengths from 1.88 in to 2.25 in, with the EMZ at 2 1/16 in. Rotation also differs: most options are reversible, but the EMZ turns CCW only.
A 2 HP motor replacement can have the right horsepower and voltage yet still have the wrong shaft or rotation. Confirm the dimensions and direction before replacing it.
How do you choose between 2 HP and 5 HP motors?
Choose the horsepower specified for your compressor rather than sizing up by preference. A different motor rating may not suit the pump, wiring or circuit.
The EMZ and JIAXINPRO are 2 HP options, the VEVOR 3.7 HP motor serves a mid-size requirement, and VEVOR, Baldor and POWORFOL offer 5 HP choices. Their frame, shaft, voltage and current details still differ.
If you are also checking compressor capacity for a 3 HP setup, the air compressor guide for a 3 HP motor can help you compare the motor rating with the compressor you need.
Final pick: which 240V air compressor motor should you choose?
Choose the VEVOR 5 HP if your compressor calls for its 230V, 56HZ frame and 7/8 in shaft; pick Baldor when you need a 208–230V motor, or a 2 HP option when your compressor requires that rating. Confirm every electrical and mechanical detail before installation, and review air compressor motor oil guidance if you're servicing the pump during the repair.

Frequently asked questions
Is a 240V motor the same as a 230V air compressor motor?
Many motors sold for nominal 240V systems are labeled 230V or 208–230V. Use the motor's stated voltage range and your compressor's wiring requirements to check compatibility.
If the motor supports multiple voltages, follow its wiring diagram and have a qualified person handle electrical work.
How do I know if a 240V motor will fit my compressor?
Compare the motor's horsepower, frame, shaft diameter, shaft length, rotation direction and mounting dimensions with the compressor's requirements. A matching voltage alone does not ensure a fit.
Also check the pulley alignment and electrical circuit before replacing the motor.
Can I use a 5HP motor on a compressor that came with a 3HP motor?
Only if the compressor manufacturer specifies that motor rating as compatible. The pump, belt, mounting, wiring and circuit all need to support the replacement.
A higher horsepower label by itself does not make a motor a safe or suitable swap.
What does a 56 frame mean on an air compressor motor?
A 56 frame is a motor mounting size, but it does not tell you every fit dimension. Shaft diameter, shaft length, mounting holes and pulley position still matter.
Compare those measurements with your old motor or compressor manual before ordering.
Does rotation direction matter when replacing a compressor motor?
Yes. The motor needs to turn in the direction required by the compressor's pump and belt setup.
Some options here are reversible, while the EMZ 2 HP motor is CCW only.
Confirm the required direction before wiring or installation.
