CNC Spindle Motor 2.2 kW, 24000 RPM, 220V Water Cooled ER20
The 2.2 kW Water-Cooled CNC Spindle Motor is a high-performance industrial solution engineered for a wide range of precision machining tasks. Operating on a standard 220V architecture, this motor is particularly well-suited for specialized applications such as high-security lock and key manufacturing, soft metal carving, and wood engraving. Delivering a consistent 0.87 Nm of torque at a peak speed of 24,000 RPM, it provides the rotational stability required for smooth surface finishes and tight dimensional tolerances. The motor is built with a precision 4-bearing configuration, utilizing two 7005 P4 bearings at the front and two 7002 P4 bearings at the rear to handle both radial and axial loads effectively. Its integrated water-cooling system ensures maximum thermal management during continuous duty, making it a reliable component for industrial CNC machines and advanced robotics arms. Equipped with a robust ER20 collet system supporting tool shanks up to 13mm, this 5.4 kg spindle offers the perfect balance of power and precision for modern fabrication environments.

Technical FAQ & Operational Guide
Can I run this 2.2 kW 220V spindle on single-phase household power?
While the motor is 220V, it must be driven by a Variable Frequency Drive (VFD). You can use a VFD that takes single-phase 220V input and outputs the required 3-phase power to the spindle. This makes it ideal for smaller workshops and advanced hobbyist setups.
Why is this model recommended for robotics arms?
At 5.4 kg, this spindle offers an excellent power-to-weight ratio. Its compact cylindrical body and water-cooling (which doesn't blow air/dust around sensitive robot joints) make it an ideal end-effector for high-precision industrial robotics arms.
Is the ER20 collet necessary for soft metal carving?
Yes. Soft metal carving (like aluminum or brass) requires higher clamping forces and the ability to use larger material removal bits compared to fine engraving. The ER20 system provides the necessary rigidity and supports tool shanks up to 13mm to ensure accurate results.
