9 Best Air Compressor 5 HP Motor (November 2026)
The best air compressor 5 hp motors include the VEVOR 5HP Air Compressor Electric Motor for most 5 HP replacements, the VEVOR 2HP Air Compressor Electric Motor for dual-voltage 2 HP setups, and the Metabo HPT Pancake Air Compressor for buyers who need a complete compressor.
On this page (5 sections)
The VEVOR 5HP Air Compressor Electric Motor is the best air compressor 5 hp motor for most replacements because it combines a 56HZ frame, 7/8 in keyed shaft, 230V power and reversible rotation.
That combination covers the most common replacement checks in one place. Confirm that your compressor pump, mounting feet and pulley expect those same measurements before ordering.
The right choice still depends on your old motor's shaft, frame, voltage, current and rotation. Horsepower alone does not prove that a motor will bolt on or turn the pump correctly.
A motor with the wrong shaft length, keyway or mounting pattern can turn a simple replacement into extra work. Slight differences also affect pulley alignment and belt tracking.
Electrical matching matters just as much as physical fit. Voltage, amperage, phase and rotation determine how the motor is wired and which way it runs.
If your compressor uses 240V power, compare these picks with our guide to the best 240V air compressor motor.
That guide can help when your shop circuit and a 230V nameplate need careful reconciling. The motor, wiring and breaker must all agree.
If the motor is an Ingersoll Rand unit, start with our guide to the best replacement motors for Ingersoll Rand air compressors.
Take your time with the nameplate for each pick and compare numbers line by line. A careful match at the start usually makes setup and care simpler later.

The best air compressor 5 hp motors for replacement jobs
The best 5 HP motor for your compressor is the one that matches its nameplate and mounting details. We compared horsepower, voltage, frame, shaft measurements, rotation and practical replacement needs.
VEVOR 5HP Air Compressor Electric Motor: Best for most 5 HP replacements
- 5 HP
- 230V
- 25 amps
- 56HZ frame
- 7/8 in keyed shaft
- 3450 RPM
- CW/CCW rotation
The 56HZ frame and 7/8 in keyed shaft cover the main measurements many 5 HP compressor replacements require. Its 230V, 25-amp single-phase setup and reversible rotation give you useful wiring flexibility.
Pros
- Reversible CW/CCW rotation
- Steel construction
- CSA certification
Cons
- For clean, dry environments
- Requires a customer-supplied 60-amp circuit breaker
VEVOR is the strongest all-around pick for a standard 5 HP replacement. Its 56HZ frame, 7/8 in keyed shaft and 2.25 in shaft length give you the main mechanical measurements to compare with the original motor.
The motor runs at 230V, draws 25 amps and turns at 3450 RPM. It is single phase, and the rotation can be set for clockwise or counterclockwise operation.
The factory setting is CCW.
The open drip-proof design is intended for clean, dry environments. The motor has a steel shell and weighs 40.8 lb.
VEVOR includes the motor and an instruction manual, while the customer supplies the circuit breaker rated at 60 amps.
Choose this motor when your existing unit matches the 56HZ frame and keyed shaft. Check the wiring diagram and have a qualified person confirm the circuit before connecting it.
If you plan to keep the existing pressure control, see using an old compressor pressure switch.
VEVOR 2HP Air Compressor Electric Motor: Best for dual-voltage 2 HP setups
- 2 HP
- 115/230V
- 20/10 amps
- 56 frame
- 5/8 in keyed shaft
- 3450 RPM
- CW/CCW rotation
This is a 2 HP replacement rather than a 5 HP motor, but its dual-voltage design makes it useful when a compressor nameplate supports either 115V or 230V.
Pros
- 115V and 230V operation
- Reversible rotation
- CSA certification
Cons
- Not a 5 HP motor
- Requires different circuit breaker sizes at 115V and 230V
The VEVOR 2HP motor is for a 2 HP compressor, not a 5 HP pump. Its main advantage is 115V/230V flexibility, with 20 amps at 115V and 10 amps at 230V.
That dual voltage design suits a home garage on a standard household circuit or a shop wired for 230V. You still need to set the wiring for the voltage you plan to use and use the matching breaker.
It uses a 56 frame, 5/8 in keyed shaft, 1.88 in shaft length and 3450 RPM. Those measurements should be compared with the original motor before you assume it will fit your pump and pulley.
Rotation is reversible between CW and CCW, with CCW as the factory setting. The open drip-proof steel construction calls for a clean, dry environment.
VEVOR specifies a 50-amp customer-supplied breaker at 115V or a 25-amp breaker at 230V. Pick it when your compressor is designed around 2 HP.
It is not a suitable power substitute for a true 5 HP motor.
Metabo HPT Pancake Air Compressor: Best for buyers who need a complete compressor
- 6-gallon tank
- 165 PSI
- 1 HP oil-free motor
- 2.8 CFM at 90 PSI
- 3.7 CFM at 40 PSI
- Two 1/4 in quick couplers
This complete 6-gallon compressor is not a replacement motor, but it fits buyers who need a portable compressor instead of rebuilding a 5 HP unit.
Pros
- Portable 38.5 lb design
- Oil-free motor
- Two quick couplers
Cons
- Only 1 HP
- Not a motor-only replacement
The Metabo HPT is the outlier in this roundup because it is a complete portable compressor rather than a replacement motor. Its 6-gallon tank, 165 PSI maximum and 1 HP oil-free motor suit buyers who need a new compressor.
That makes it a different kind of choice from the motor only picks above. You are not matching a frame or shaft here, so you can focus on tank size, pressure and airflow for the tools you plan to run.
It produces 2.8 CFM at 90 PSI and 3.7 CFM at 40 PSI. Those figures say more about daily use than pressure alone, because they show how much air the compressor can supply while a tool is working.
Two 1/4 in universal quick couplers support fast tool changes. The 38.5 lb design is easier to move than the large 5 HP motor options.
Metabo HPT describes it for tasks such as brad nailing and finish nailing. The compressor has a 73 dB operating noise level and a 46-second tank recovery time.
The oil free motor also reduces routine maintenance compared with an oil lubricated pump. Choose this model when replacing the whole compressor makes more sense than fitting a motor.
It does not replace a 5 HP motor on a larger pump.
BALDOR 5HP AIR COMPRESSOR ELECTRIC MOTOR: Best for 208V flexibility
- 5 HP
- 208/230V
- 3450 RPM
- 56HZ frame
- 7/8 in shaft
- 1.15 service factor
- CW/CCW rotation
Baldor suits a 5 HP compressor setup that needs 208V or 230V support. Its open drip-proof enclosure is intended for dry indoor environments.
Pros
- Usable at 208V
- Reversible rotation
- Mounting hardware and wiring schematic included
Cons
- For dry indoor environments
- 50 lb motor
Baldor is the best fit here when your electrical setup may use 208V or 230V. It is a 5 HP, single-phase motor with a 56HZ frame, 7/8 in shaft diameter and 3450 RPM.
That voltage range gives it an edge in some commercial and industrial buildings where 208V is common. If your supply is closer to 230V, the same motor can still be used within its stated range.
The motor draws 21.5 amps at 230V and 23.5 amps at 208V. The higher current at 208V is worth planning for, because breaker size, wiring and voltage drop all need to suit the lower voltage condition.
Its 1.15 service factor is specified at 230V, and it is usable at 208V. Rotation is reversible between CW and CCW.
The open drip-proof enclosure is designed for dry indoor environments. The 50 lb motor includes mounting hardware and a wiring schematic.
Choose Baldor when the nameplate and mounting layout match and 208V support matters. Confirm the base and shaft length before ordering because the title does not give a shaft length.
POWORFOL 5 HP Electric Motor: Best for a 20-amp 230V setup
- 5 HP
- 230V
- 20 amps
- 3450 RPM
- 56 frame
- 7/8 in keyed shaft
- CW/CCW rotation
POWORFOL gives you a 5 HP, 230V single-phase motor with a 56 frame and keyed shaft. Check the existing motor's current draw and mounting measurements before treating it as a match.
Pros
- Alloy steel construction
- Reversible rotation
- 56 frame
Cons
- Open drip-proof design
- The product data describes it for clean, dry environments
POWORFOL gives you a 5 HP, 230V single-phase motor rated at 20 amps and 3450 RPM. Its 56 frame, 7/8 in keyed shaft and 2.25 in shaft length make it a direct comparison with other common 5 HP replacement layouts.
Those three measurements are the first things to check against your old motor. Frame, shaft diameter and shaft length decide whether the pulley and mounting feet line up without extra work.
The motor supports CW and CCW rotation. Reversible rotation can simplify installation when the compressor layout does not give you much freedom to mount the motor the other way around.
It uses alloy steel construction, weighs 47 lb and includes the electric motor. The weight is a reminder to check that your mounting surface and fasteners are up to the job before you lift it into place.
The open drip-proof design is recommended for clean, dry environments. That means a protected workshop or utility area is the right setting, with routine checks for dust build up around the motor.
The product data also identifies a 3700-watt rating, so compare the current draw and electrical setup with the old motor rather than relying on horsepower alone. Amps and wattage both help you sense whether the circuit and breaker are a sensible match.
Choose POWORFOL when your compressor matches these mechanical measurements and needs a 20-amp, 230V motor. Check the mounting holes and wiring before installation.
In practical terms it suits a straightforward replacement where the old motor already uses this frame and shaft pattern. If any measurement differs, pause and compare another pick rather than forcing the fit.
Century 3D 5 HP 3450 RPM R56Y Frame: Best for a rigid-base replacement
- 5 HP
- 3450 RPM
- 208-230V
- 56Y frame
- 7/8 in keyed shaft
- 22 amps
- 1.15 service factor
Century is aimed at a rigid-base compressor motor replacement with a 56Y frame, 7/8 in keyed shaft and 208-230V operation.
Pros
- Manual thermal protection
- Ball bearings
- Capacitor-start/run design
Cons
- CCWSE shaft rotation
- Open drip-proof enclosure
Century suits a rigid-base compressor that needs a 56Y frame, 7/8 in keyed shaft and 208-230V operation. It is rated at 5 HP, 3450 RPM and 22 amps.
The rigid base is the detail that sets it apart from some other picks. If your compressor was built around that mounting style, the motor can sit and align in the way the original unit did.
The motor uses a 2.25 in shaft length, ball bearings, capacitor-start/run design and manual thermal protection. Those features describe a compressor duty motor built to start under load and protect itself when heat builds up beyond a safe point.
Its service factor is 1.15, and the enclosure is open drip-proof. The service factor gives some margin in the motor rating, while the enclosure still calls for a clean, dry location.
Rotation is CCWSE, so this motor is a poor match if your pump requires clockwise rotation and the installation cannot accommodate a change. Rotation is not a small detail on a compressor, because the pump is designed to turn one way.
The motor weighs 48.1 lb. That weight makes a second pair of hands useful during installation, especially when you are lining up the base, pulley and belt at the same time.
Pick Century when your old motor has the same rigid-base, 56Y and shaft details. Read the nameplate carefully because frame and shaft style are more useful than the 5 HP label by itself.
For care, keep the motor dry, clean and well ventilated, and check belt alignment after mounting. A motor that matches on paper still needs careful set up to run smoothly from day one.
JIAXINPRO 2HP Air Compressor Motor: Best for 115V or 230V home workshops
- 2 HP
- 115/230V
- 3450 RPM
- 56 frame
- 5/8 in keyed shaft
- 1.88 in shaft length
- CW/CCW rotation
This 2 HP motor suits a standard 56-frame compressor that uses a 5/8 in keyed shaft. Its dual-voltage setup works with household 115V or shop 230V circuits.
Pros
- Dual-voltage operation
- Reversible rotation
- Manual-reset overload protector
Cons
- Not a 5 HP motor
- Open drip-proof construction
JIAXINPRO is a 2 HP replacement for compressors using a 56 frame and 5/8 in keyed shaft. It runs at 3450 RPM and supports either 115V or 230V operation.
That dual voltage range suits a home workshop that may move between circuits. Follow the wiring diagram for the voltage selected and confirm the breaker suits that setting.
The shaft is 1.88 in long. Compare that length with your original motor, because a close shaft diameter does not help if the pulley cannot sit correctly.
Rotation is electrically reversible between CW and CCW, and the motor includes an external manual-reset overload protector. The protector gives a clear reset point if the motor trips.
Its rolled-steel, open drip-proof construction protects against dust and moisture in workshop conditions. It still belongs in a clean, dry spot, with regular checks to limit dust buildup.
The motor weighs 31 lb and has a 1.5 kW rating. Its lighter weight can make replacement more manageable, although safe lifting and secure mounting still matter.
Choose it for a 2 HP home workshop compressor when the old motor shares the same frame, shaft and voltage requirements. Do not use its dual-voltage feature as a reason to replace a 5 HP motor with it.
A.O. Smith AC motors B813 5 HP: Best for a simple 230V 5 HP match
- 5 HP
- 3450 RPM
- 230V
- 22 amps
- 56HZ frame
- 7/8 in by 2.31 in flat shaft
The B813 is a straightforward 5 HP, 230V compressor motor with a 56HZ frame and flat shaft. Confirm the shaft style because it differs from keyed-shaft options.
Pros
- 5 HP compressor-duty design
- 3450 RPM
- 230V operation
Cons
- CWLE rotation
- 1 service factor
The A.O. Smith B813 is a simple 5 HP compressor motor for a 230V setup.
It runs at 3450 RPM, draws 22 amps and uses a 56HZ frame. Those numbers give you a clean starting point for comparing it with the old motor on your compressor.
Its 7/8 in by 2.31 in flat shaft is the key detail to check. A flat shaft is not the same as a keyed shaft, so compare the pulley and shaft on your existing motor before choosing it.
That distinction can decide the whole replacement. A pulley made for a keyed shaft may not seat properly on a flat shaft, and the reverse can also cause problems at the belt line.
The motor uses a 1 service factor and CWLE rotation. A 1.0 service factor means the motor is rated for continuous operation at its stated load without the extra margin described by higher service factor motors.
Its copper construction weighs 43.3 lb. Check that your mounting arrangement can support that weight and keep the motor aligned while the belt is fitted and tensioned.
Choose the B813 when your compressor requires this flat-shaft layout and clockwise rotation. If your old motor uses a keyed shaft, one of the keyed options above may be a closer mechanical match.
For set up, confirm the shaft length and flat section against the pulley before you wire anything. A short check at that stage can prevent a return or a redesign of the mounting arrangement.
DDL New 198FA 3.7HP: Best for replacing a 5 HP SPL motor
- 3.7 HP
- 230V
- 17.2 amps
- 56 frame
- 3450 RPM
- 5/8 in shaft
- CCW rotation
DDL targets compressors marked 5 HP SPL or SPL with a 15-17 amp rating at 230V. It is a 3.7 HP motor, so match the old motor's SPL marking and current before choosing it.
Pros
- Designed for a specific SPL replacement pattern
- 56 frame
- 3450 RPM
Cons
- Rotation is CCW and not reversible
- Professional installation required
DDL is designed for a specific replacement pattern: a compressor marked 5 HP SPL or SPL with a 15-17 amp rating at 230V. The motor itself is rated at 3.7 HP, uses a 56 frame and turns at 3450 RPM.
That SPL marking is the reason to pause and read carefully. This is not a general 5 HP motor, even though the replacement pattern name includes 5 HP SPL.
It has a 5/8 in keyed shaft with a 2.25 in shaft length. Those measurements need to match the old motor, along with the frame, before the motor can be treated as a direct replacement.
Rotation is CCW when viewed from the shaft end, and it is not reversible. If your pump needs clockwise rotation, this motor will not suit it, and rewiring will not change that limit.
The motor uses 17.2 amps at 230V and has a 1.0 service factor. The current figure is close to the SPL replacement range, which is why the old motor rating matters so much here.
Professional installation is required. That instruction fits the narrow purpose of this motor, because a mismatch in rotation, shaft or current could leave the compressor unusable.
Choose DDL only when the old motor's SPL marking, current, frame and shaft match this pattern. It is a specialized replacement, not a general 5 HP motor.
For most buyers the safer move is to treat SPL as a filter, not a selling point. If your nameplate does not show that pattern, look at the standard 5 HP keyed shaft options instead.
How to match an air compressor motor before buying
Match the nameplate and physical measurements before comparing brands. Write down the old motor's horsepower, voltage, phase, amps, RPM, frame, shaft diameter, shaft length, shaft style and rotation.
Each item answers a different practical question. Frame and shaft details decide fit, while voltage, amps and rotation decide whether the motor can run the pump correctly.
Horsepower alone is not enough. The VEVOR 5 HP and Baldor 5 HP motors both use 7/8 in shafts, but their electrical details differ.
That difference can change the breaker, wiring and setup. The A.O.
Smith B813 uses a flat shaft, while many other choices use keyed shafts, which also affects the pulley and belt tracking.
Check whether the compressor needs a rigid base or another mounting layout. Measure the shaft and compare the keyway or flat section, mounting holes and base style.
A motor at the wrong height can make belt alignment difficult, even if the shaft diameter looks correct. Rotation also matters, as several motors support CW and CCW operation but the DDL motor is CCW and not reversible.
Service factor and enclosure type are worth checking as well. Writing old motor details down will make comparisons faster and safer.
Should you choose 230V or 115V?
Choose the voltage that matches the compressor circuit and motor nameplate. A dual-voltage motor can offer more wiring options, but it still needs the correct breaker, wiring and configuration.
Dual voltage does not mean any voltage will do. It means the motor can be set for one of the listed voltages, and the rest of the electrical installation must follow that choice.
The VEVOR 2 HP and JIAXINPRO 2 HP motors support 115V and 230V. The 5 HP VEVOR, POWORFOL and A.O.
Smith options are 230V choices, while Baldor supports 208V and 230V.
That split matters when you move a compressor between a garage, a workshop and a commercial building. Current draw changes with voltage on dual-voltage motors, with higher amps at 115V and lower amps at 230V on the VEVOR 2 HP example.
Do not guess from the wall outlet. Use the wiring diagram and confirm the circuit with a qualified electrician.
A plug that fits is not proof that the circuit is right for the motor.
Our guide to how many watts a 1 HP air compressor uses explains why motor size and electrical demand should be checked together. Wattage, amps and horsepower describe related but different things.
If voltage, breaker or rotation is unclear, get professional help before you connect the motor. That caution is especially important with 230V compressor motors that can draw substantial current.
How should you install and care for a replacement motor?
Disconnect power before working on the compressor, release stored air and follow the motor's wiring instructions. Professional installation is the safer choice when the voltage, breaker or rotation is unclear.
Take those steps in order and do not rush the first connection. A replacement motor can look simple once it is bolted in, but the electrical and rotation checks decide whether it will run safely.
Keep open drip-proof motors in clean, dry environments. Protect the motor from water, dust buildup and blocked airflow, then check the pulley alignment and belt tension after mounting.
Clean air around the motor helps it shed heat and keeps dust from collecting on the parts that need to stay clear. A quick visual check each time you use the compressor is a simple habit.
Use the correct shaft key and pulley arrangement for the compressor pump. A shaft that appears close in size may still be wrong if the length, keyway or flat section does not match.
Belt alignment should be checked with the guard refitted and the motor secure. Small alignment errors can show up as noise, vibration or uneven belt wear in daily use.
Inspect unusual heat, vibration, noise or repeated breaker trips before continued use. Those signs can point to a wiring fault, a mounting problem or a motor that is being asked to do more than it should.
For planning a replacement, our guide to the average lifespan of an air compressor motor covers the signs that a motor may be nearing the end of its useful service.
Which air compressor 5 hp motor should you choose?
Pick the VEVOR 5HP Air Compressor Electric Motor when your compressor needs a 230V, 25-amp, 56HZ motor with a 7/8 in keyed shaft and reversible rotation. Choose Baldor for 208V flexibility, Century for a rigid-base 56Y match and A.O.
Smith for a confirmed flat-shaft layout.
Choose POWORFOL when its 20-amp electrical rating and shaft measurements match. That pick suits a standard 5 HP layout where the old motor already uses the same frame, shaft diameter and shaft length.
Consider DDL only for the specific 5 HP SPL replacement pattern, and choose the 2 HP motors only for compressors built around 2 HP. Those limits are not a weakness when they match your nameplate, but they become a problem when they do not.
The Metabo HPT belongs in a different category again. It is the choice when you need a complete portable compressor rather than a motor to rebuild an existing unit.
The safest buying rule is simple: match the old motor's electrical and mechanical details first, then use brand, construction and rotation flexibility to break a tie.
In practice that means writing down voltage, amps, frame, shaft, keyway or flat section, mounting style and rotation before you compare prices or features. Once those details line up, the right pick usually becomes clear.

Frequently asked questions
What is the best air compressor 5 hp motor?
The VEVOR 5HP Air Compressor Electric Motor is the strongest general choice here because it combines a 56HZ frame, 7/8 in keyed shaft, 230V single-phase power, 25 amps and reversible CW/CCW rotation. Confirm your existing motor's measurements and electrical requirements before ordering.
How do I match an air compressor motor?
Match horsepower, voltage, phase, frame, shaft diameter, shaft length, shaft style, rotation and current draw. A 5 HP motor with the wrong shaft or frame may not mount correctly, while the wrong voltage or wiring can create a serious safety risk.
Can a 2 HP motor replace a 5 HP air compressor motor?
Usually not. A 2 HP motor has less power than a 5 HP motor and may not drive the compressor pump as intended.
Choose a 2 HP replacement only when the compressor and original motor are rated for 2 HP, then match the frame, shaft and electrical details.
What does 56 frame mean on an air compressor motor?
A 56 frame identifies a motor mounting and shaft size standard, but it does not guarantee that every 56-frame motor will fit your compressor. Compare the shaft diameter, shaft length, keyway, base, bolt locations and rotation with the original motor.
Are open drip-proof compressor motors safe outdoors?
Open drip-proof motors are intended for clean, dry environments, not exposed wet conditions. Several motors here use this enclosure type.
Place the compressor in a suitable dry area, follow the wiring instructions and use professional electrical help when needed.
