1.5KW/2.2KW Water Cooled Spindle Motor, 24K RPM ER11 ER20 Collet with Pre-Wired VFD Inverter Box & Pump, 4 Bearing Precision Motor for Metal Engraving

Upgrade Your CNC Precision with the 1.5KW Water-Cooled Spindle Kit Designed for serious DIY enthusiasts and industrial workshops, this complete spindle motor kit eliminates the headache of complex VFD wiring. By integrating the inverter into a pre-wired control box, we provide a true plug-and-play experience compatible with standard US 110V power. Why Choose Water-Cooled? Unlike air-cooled spindles that can overheat during long jobs and generate excessive noise, our water-circulation system ensures the motor stays cool, protecting your bearings and tools. The included pump synchronizes with the spindle start-up for automated cooling. User-Friendly VFD The Variable Frequency Drive (VFD) features a simple, user-friendly button panel for easy operation. Safety is paramount, and it includes robust, comprehensive protection against common issues like overheating, overloading, and various voltage problems. High-Quality Bearings & 1/4 ER11 Collet (2.2KW with ER20) Optimized with four high-performance bearings, this series offers strong hardness and rust resistance. Utilizing dynamic balancing technology, the spindle achieves an exceptionally low actual runout, closely approaching 0.01 mm. Submersible Water Pump This pump delivers high lift and a large flow rate, while also featuring excellent insulation. It is essential that the pump be fully submerged in water during operation. To facilitate easy connection to the spindle motor, we include water pipes with the pump.
