About this item
Description
3KW Air Cooled Spindle Motor
ER20 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.
- Technical Parameters
- ER20 Standard Collet
- Powerful Bearing
- Low Noise & Heat Dissipation
Dynamic Balance Design
Unlike other milling spindle motors, we use innovative and advanced dynamic balancing technology. The ER20 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.
