2.2KW Water Cooled Spindle Kit, 80mm ER20 CNC Spindle Motor with VFD Control Box

Controlled Through PWM & 0-10V Signals Offers more speed control options with PWM and 0-10V signal control, allowing precise spindle speed adjustments. Compatible with machines that have a 12V PWM GND or 0-10V signal output interface. Water Pump Control Interface Activates the water pump automatically when the spindle starts, ensuring excellent heat dissipation during long-term operation. Compared to air-cooled spindles, the water-cooled system provides a quieter and more efficient working environment. Complete Kits & Integrated Design Includes essential components like the water pump, hoses, and cables for plug-and-play convenience. The inverter is housed in the electrical control box with preset parameters, eliminating the need for complex wiring and setup. Powerful Performance Equipped with a 2.2kW motor, the spindle operates steadily at 110V and 400Hz, reaching a maximum speed of 24,000 RPM. After dynamic balancing tests, radial runout is kept under 0.005mm, ensuring high precision and smooth carving performance for optimal machining results. Longevity Design Featuring a four high-precision angular contact bearings water-cooled spindle, this design ensures stable operation, extends the spindle’s lifespan, and reduces maintenance costs. Versatility This high-performance CNC spindle motor kit is highly versatile, perfect for desktop CNC routers (such as NymoLabs NBS-6050 PRO, NBS-6040, NBX-5040), DIY upgrade projects, and CNC milling machines. It easily processes a wide range of materials, including soft metals (such as 6061 aluminum, brass, steel), hardwood, plywood, MDF, acrylic, plastics, and PVC, meeting the diverse machining needs of both personal users and small workshops.
