Genmitsu CNC Spindle Motor Kit, 2.2KW, Water Cooled Spindle Motor, 24000 RPM ER20 Collet with Pre-Wired VFD Inverter Box & Pump - 4 Bearing Precision Motor for CNC Router Machine Engraving — Open-Box, 13% Off

PLUG-AND-PLAY INTEGRATED CONTROL BOX - Skip the complex wiring and VFD programming. This 2.2kW CNC spindle kit features a pre-wired electrical control box with the inverter enclosed and parameters preset. Simply plug into a standard 110V outlet to start your woodworking or metal carving projects immediately.

QUIET & EFFICIENT WATER COOLING SYSTEM - Engineered for long-duration operations, the intelligent interface automatically activates the included water pump when the spindle starts. This water-cooled design provides superior heat dissipation compared to air-cooled models and significantly reduces operating noise for a better workshop environment.

HIGH-PRECISION 4-BEARING DESIGN - Built for accuracy, the spindle motor utilizes four optimized steel bearings and dynamic balancing technology to achieve a runout close to 0.01mm. This ensures stable 24,000 RPM performance, extends cutting tool lifespan, and delivers professional-grade finishes on wood, aluminum, and plastics.

FLEXIBLE SPEED CONTROL OPTIONS - Tailor your machining process with versatile control methods. The system supports both PWM and 0-10V signal inputs, allowing precise speed adjustments via your CNC controller. Ideal for users upgrading their machines for detailed engraving or rapid material removal.

WIDELY USE: The water-cooled spindle is versatile and can be used in various machining applications, including engraving machines, milling machines, lathes, and CNC routers. It is suitable for a wide range of materials, such as stainless steel, soft aluminum, brass, stone, acrylics, PVC, PCB, wood, and nylon.

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
