2.2 kW air-cooled spindle motor
ER20 collet & four bearings & 24000 R/min
These spindle motors use imported bearings and high-quality materials, and their lifespan is three times longer than that of conventional spindle motors. They are widely suitable for engraving machines for wood, stone, metal, and other materials.
- Technical parameters
- ER20 Standard Collet
- High-performance bearing
- Low noise & heat dissipation
Dynamic balancing technology
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 upgraded bearing offers two key advantages: superior durability and corrosion protection. High speed (24,000 rpm) and powerful performance result in greater efficiency than before.
Noise reduction & air cooling
Our CNC milling spindle motor operates quietly and prevents hearing fatigue. It utilizes air circulation to cool the heat generated by the spindle at high speeds and has excellent heat dissipation.
High-quality material
The aluminum housing ensures higher performance and a longer lifespan; unlike ordinary aluminum-coated wire, the oxygen-free copper coils guarantee high-quality workmanship and engraving performance.
Refined internal details
The CNC milling spindle is a built-in wire box that connects directly to the wire or VFD, effectively improving stable and smooth operation. The upgraded wrench is designed for ease of use.
Wide application
Air-cooled engines are frequently used with materials such as wood, stone, mold, and metal. They are suitable for mechanical engineering, sheet metal fabrication, railings, factories, shipyards, DIY projects, construction, and other fields.
