About this item

【TECHNICAL PARAMETERS】- Spec: φ100 x 220 mm (Diameter: 100 mm x Length: 220 mm), Power: 3 KW, Voltage: 220V~250V, Frequency: 400 Hz, Speed: 8000-24000 R/min, Runout off: less than 0.005 mm.
【ADVANCED BALANCE TECHNOLOGY】- Dynamic balance technology can effectively reduce the noise in the process of use. The efficiency & service life of the CNC router spindle can be significantly improved. The nut using manganese steel is hardened with high precision, not easy to break the knife.
【SUPERIOR PERFORMANCE BEARINGS】- The high-speed core creates a more efficient & upgraded steel bearing, which significantly improves the hardness and rust resistance. The imported shaft has a high degree of concentricity, high precision & more durable.
【TRUSTWORTHY HEAT DISSIPATION】- Scientifically designed factory-made fan owns low noise and better heat dissipation effect. It's beneficial to the smooth & stable operation of the machine.
【WIDE APPLICATION】- The CNC spindle motor kit is mainly used for engraving machine or used with frequency converter. It uses water circulation to cool the heat generated by the spindle at high speed and has a good heat dissipation effect.

Updated 3KW Water-cooling High Speed High Precision Spindle Motor New

3KW Water Cooled Spindle Motor

These spindle motor motors adopt Germany imported bearing, which can make it use for three times longer useful time than ordinary spindle motor. In an extremely high-speed working environment, the ordinary bearing can not ensure this high speed for a long time. Our Germany imported bearing can make spindle motor three times longer useful time than ordinary spindle motor.

Dynamic Balance Design

Unlike other milling spindle motors, ours use innovative & advanced dynamic balancing technology. The distinct advantages are low noise, upgraded efficiency & extended service life.

Powerful Bearing

Upgraded bearings have two main advantages of superior durability & anti-rust performance. Greatly- improved high-speed core brings higher efficiency than the past.

Anti-rust Material

The use of acid-proof materials makes the CNC router spindle motor more durable & sturdy. The metal casing significantly improves cooling efficiency & faster dissipates heat.

High Concentricity & Precision

With high accuracy & concentricity, our bearings are much superior to other manufacturers on the market. One-time molding design brings more excellent precision to the CNC spindle mount.

Er20 Standard Collet

The Er20 standard collet features high precision & dynamically balanced design, which effectively avoids the risk of knife breakage.

Application Fields

Water-cooled motors mainly match with engraving machines or frequency converters, and commonly applied materials such as wood, stone, mold & metal, etc.

I've owned another one of these bought from a different supplier, and that wasn't grounded on the body, however, this one was and I'm really happy with it so far, it's very quiet and it comes with good quality spanners and a couple of ER20 Collets to get you started

I decided to purchase the water cooled spindle as a back up to my air cooled spindle. I use the water cooled for big jobs as to keep the temperature down

Received very quick, haven_ used yet as still gathering parts of my cnc diy build. Checked the earth pin in the plug not connected, not good for the UK market. Will have to run a separate earth to the spindle holder. One star off for that problem.
