RATTMMOTOR CNC Spindle Motor 2.2KW Air Cooled Spindle Motor 220V 80mm Spindle Motor ER20 Collet 3HP 24000RPM High Speed Spindle Motor 8A 400Hz for CNC Router Engraver Milling Machine

✅【How to Connect The Spindle Motor】The spindle motor's aviation plug marked with number 1, 2, 3, 4. Number 1, 2, 3 port are connected with inverter's port U, V, W respectively. Number 4 is the ground wire, no wiring is required.
✅【Basic Parameters】- Diameter: 80 mm x Length: 195 mm, Power: 2.2KW, Voltage: 220VAC, Current: 8A, Frequency: 0-400Hz, Collet Size: ER20, Runout off: Less than 0.01mm, Precision Tapered Bore: Less than 0.005mm, Speed: 0-24000rpm (Please keep the speed of spindle rotation above 9000 rpm.)
✅【Cooling Method】- Good heat dissipation effect by adopting fan cooling method, without connecting to water pump and water pipe, it's more convenient and trouble-saving and can be used directly by connecting with the inverter.
✅【Rotation Accuracy】- The rotor has high precision because of precision steel ball retainer, and high temperature resistant grease lubrication method, all of which ensures the rotation accuracy and low noise of the spindle during high-speed grinding.
✅【Material & Configure】- The spindle has fine workmanship, 3 bearings, stainless steel body and dustproof design make the spindle more durable.
✅【Main Application 】This spindle motor is mainly designed for CNC router machine and usually used with VFD Inverter, engraving materials such as wood, aluminum, glass, PVC industry ,ect.
