About this item

Technical Parameters: Spec: φ3 x 13 in (Diameter: 7.5 cm x Length: 33.9 cm); Power: 4KW; Voltage: 220V; Current: 13.5A; Collet Size: ER25; Bearings: 4 bearings; Frequency: 300 Hz; Speed: 18000 R/min; Runout off: less than 0.002 mm. Mainly used for engraving machine or used with frequency converter.
ER25 Standard Collet: The collet of the CNC router spindle is quenched with manganese steel, and the runout is less than 0.002mm, which has high precision and is not easy to break the knife, increasing the stability of the working process. Dynamic balance technology can effectively reduce noise during use.
Powerful Bearing: The air spindle motor adopts imported bearings with high accuracy, precision, and durability. Significantly improve the hardness and anti-rust performance.
Low Noise & Heat Dissipation: The dynamic balance technology can effectively reduce the noise during use. The scientifically designed air cooling system has a better heat dissipation effect to ensure smooth operation.
Wide Application: The CNC spindle motor kit is mainly used for engraving machines or frequency converters. It uses air circulation to cool the heat and has a good heat dissipation effect.

4KW Air Cooled Spindle Motor

ER25 Collet & Four Bearings & 18000 R/min

These spindle motors adopt imported bearings and high-quality materials, and their service life is three times that of ordinary spindle motors. Widely applicable to engraving machines for wood, stone, metal, and other materials.

Low Noise & Heat Dissipation

Dynamic Balance Design

Unlike other milling spindle motors, we use innovative and advanced dynamic balancing technology. The ER25 standard collet's advantages are excellent rigidity, full strength, unique drainage design, and high precision.

Four High-quality Bearings

The upgraded bearing has two significant advantages: superior durability and anti-rust performance. High speed (18000R/min) and strong power bring higher efficiency than before.

Noise Reduction and Air Cooling

Our CNC router spindle motor works with low noise and avoids auditory fatigue. It uses air circulation to cool the heat generated by the spindle at high speed and has a good heat dissipation effect.

Premium Material

The aluminum body ensures greater power and longer life; Unlike ordinary aluminum-clad wire, the oxygen-free copper coils can ensure high-quality processing and engraving performance.

Refined Internal Details

The CNC router spindle is a built-in wire box directly connected to the wire or VFD, effectively improving the stable and smooth operation. The upgraded wrench is provided for easy handling.

Wide Application

Air-cooled motors commonly applied materials such as wood, stone, mold & metal, etc. Suitable for machinery manufacturing, sheet metal processing, guardrails, factories, shipyards, home improvement, construction, and other fields.

I bought five to start. All worked on day one for an equipment build. I moved the equipment to a plant about 30 miles away on a cold day. After setup, two of the five motors didn’t work. I megged both and they failed at the 1000v range. I bought two more because I’m going in circles to try and get warranty issued. Only one of the two new motors worked. In summary, buy twice the amount you need to get enough working.

This has been a great working tool for my CNC carving set up. It's a strong and quiet beast of a spindle, and was just getting broken in when I managed to strip the collet threads on the shaft after maybe a hundred bit changes. Probable was overtightening the collet nut. I'm getting a torque wrench to be more precise. Very happy with this spindle.

The days when "Made in China" was a red flag for poor quality items are in the past. This air-cooled spindle is quieter than most I've heard, it is entirely vibration free, it is powerful, and it uses all collets up to and including 1/2". The Huanyang VFD required no adjustments of settings in place from the previous spindle, so the installation was easy. Including soldering the leads, it was a 10 minute job. This spindle has been in daily use for many months now, and there are no defects or problems to report. This spindle is a terrific bargain. You actually get quite a bit more than you pay for.

We needed a replacement spindle for one of our CNC mills, and this was perfect. Shipping was very quick, so there was virtually no down time. So far, it's running great and cuts well. No complaints.

Excellent Spindle, cuts wood with no issue. It is being driven by the corresponding VFD from Vevor 2.2kw 220V input single phase, without any issue. I just added two computer fans to force the air around the spindle and keep it cool, its temperature is about 45C when the room temperature is about 30C (summer !).

Jonathan Jones

These are great spindles. I have 2 of them. I run them on my V1 Engineering CNC Machines and they do amazing. So much quieter than the dewalt palm router I was using before. The only complaint I have is I wish I could set the VFD to show RPM. It might be possible and I just haven’t figured it out yet. Still a great spindle and it’s easy math to convert the Hz to rpm in my head.

Should come with cable

I love this spindle. But it should at very least come with cable to connect the spindle to the crontroller

David P.

Buy the warranty that is offered with the purchase.

This is a great replacement spindle for my CNC machine.
