CNC Spindle Motor 4.5 kW, 24000 RPM, 380 V Water Cooled
The 4.5 kW CNC Water-Cooled Spindle Motor is a robust industrial solution engineered for high-torque and high-speed operations. Operating at 24,000 RPM with a 380V 3-phase input, this motor is specifically designed to handle the rigorous demands of stone carving, marble profiling, and intricate wood machining. The integrated water-cooling system ensures exceptional thermal management, allowing for continuous operation in demanding environments without accuracy loss or component fatigue. Equipped with a precision P4 bearing configuration (7005 & 7003), it delivers smooth performance and minimal runout, making it equally effective for machining soft metals like aluminum, brass, and copper. The ER20 collet system provides the versatility needed for a wide range of industrial tooling.

Technical FAQ & Operational Guide
Why is water cooling preferred for marble and stone carving?
Stone machining generates significant heat and abrasive dust. Water cooling provides a sealed, high-efficiency thermal management system that keeps the motor at a constant temperature even during long, high-torque operations, unlike air-cooled systems that can be affected by dust.
Can this motor be run on a single-phase supply?
No, this model is designed for an industrial 380V 3-phase supply. You will need a compatible 3-phase VFD to operate this motor correctly.
What size tools can I use with the ER20 collet?
The ER20 collet system on this 4.5 kW spindle allows you to clamp tool shanks from 1mm up to 13mm, providing range for both fine engraving and heavy material removal.
