Dynamic Balance Design

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

Powerful Bearing

Upgraded steel 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.

Premium Heat Dissipation

Particular fans adopted original scientific design, low noise & better heat dissipation effect. It’s beneficial to the smooth & stable operation of the machine.

Application Fields

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

7.5KW Air 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.
