Air-cooled spindle motor, 2.2 kW
ER20 collet & four bearings & 12000-24000 rpm
These spindle motors use imported bearings and high-quality stainless steel materials, and their lifespan is three times longer than that of ordinary spindle motors. Widely used in engraving machines for wood, stone, metal, and other materials.
- Technical parameters
- ER20 Standard Collet
- High-performance bearing
- Low noise level and heat dissipation
Dynamic balance design
Unlike other milling spindle motors, we use an innovative and advanced dynamic balancing technology. The advantages of the ER20 standard collet include excellent rigidity, high strength, a unique drainage design, and high precision.
Four high-quality bearings
The improved bearing offers two key advantages: superior durability and corrosion protection. High speed (12,000–24,000 rpm) and powerful performance ensure greater efficiency than before.
Noise reduction and air cooling
Our CNC milling spindle motor operates quietly and prevents ear fatigue. It utilizes air circulation to cool the heat generated by the spindle at high speed and has excellent heat dissipation.
High-quality material
The stainless steel housing ensures higher performance and a longer lifespan; unlike ordinary aluminum-sheathed wires, the oxygen-free copper coils guarantee high-quality workmanship and engraving performance.
Refined internal details
The CNC milling spindle features an integrated, improved aviation connector that easily allows current flow and achieves the intended function of the circuit, effectively improving stable and smooth operation.
Wide application
Air-cooled motors for commonly used materials such as wood, stone, molds and metal, etc. Suitable for mechanical engineering, sheet metal fabrication, railings, factories, shipyards, DIY projects, construction and other fields.
