Introduction: 1. Water cooled spindle motor: 300w, 800w, 1.2kw, 1.5kw, 2.2kw, 3kw, 3.2kw, 4kw, 4.5kw, 5.5kw. 2. Air cooled spindle motor: 800w, 1.5kw, 2.2kw, 3.5kw, 4.5kw, 6kw, 7.5kw, 12kw. 3. Air cooled ATC spindle motor: 4.5kw, 6kw, 7.5kw, 9kw. 4. Water cooled ATC spindle motor: 1.5kw, 2.2kw, 5.5kw, 6kw, 7.5kw. 5. We provide complete set of cnc router parts and accessories, such as water cooling spindle, air cooling spindle, inverter(VFD), collet, cutter tools, DSP handle, controller, water pump etc. Features: 1. Forceful engraving, high precision, long life time. 2. Water cooling spindle is ultra quiet with long life bearings and designed for harsh environment operations. 3. Use coolant liquid circulation system to remove the temperature rise caused by high speed rotation. 4. Water-cooled spindle can run for a long time without deviation, regardless of room temperature. 5. Every spindle motor must be passed dynamic balance to improve spindle concentricity and to increase motor working life. Application: 1. Application: Industrial engraving, carving, milling, drilling etc. 2. Applicable machine: CNC router, CNC engraver, CNC wood lathe.

Secondly, we need to connect spindle to inverter. 1. Connection between Fuling inverter(vfd) and electricity supply(input voltage). If your electricity supply is single phase, 220V, please connect electricity supply to terminal "R" and "T" on Fuling inverter. If your electricity supply is three phase, 220V, please connect electricity supply to terminal "R", "S" and "T" on Fuling inverter. 2. Connection between Fuling inverter and spindle. Spindle has terminals 1, 2, 3. And fuling inverter has terminals U, V, W. Firstly, we need to find three electric wires. Secondly, please match terminals 1,2,3 with terminals U,V,W.CNC Machine Parts manufacturer website:http://www.lasercnc.com/machine-spare-parts/cnc-machine-parts/
