RATTMMOTOR CNC Spindle Motor Kit 2.2KW Air Cooled Spindle Motor ER20 220V 24000RPM 8A 400HZ with 2.2KW 3HP Single Phase to 3 Phase VFD Variable Frequency Drive Converter Speed Control for CNC Router - RTM2.2-220

• 【Spindle Motor ER20 Collet】The 2.2KW 8A air-cooled spindle motor volate is 220V, frequency is 400HZ ,and less than 0.01mm runout off, 0-24000RMP speed. It should be noted that the spindle speed must be kept above 9000 rpm, otherwise the spindle will be damaged. 【Spindle Motor Features】①Good 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. ② The spindle has fine workmanship, 3 bearings, stainless steel body and dustproof design make the spindle more durable. 【VFD Inverter Parameters】Power:2.2KW, Input Voltage: 220V(+/-15%) ,Output Voltage 220VAC, Input Frequency: 50-60Hz, Output Frequency: 0-1000Hz, Input Phase: 1 phase, Output Phase: 3 phase, Current: 11A.It provide a variety of fault protection functions: over-current, over-voltage, under-voltage, over-heat, overload, lack of equal real-time monitoring and protection to ensure safe operation. 【VFD Inverter Advantages】Other Fuctions: With over torque and under torque detection. With jump frequency control function, it can effectively suppress mechanical resonance and make the system more stable and reliable.It can also avoid the impact of production due to instantaneous power failure because of instantaneous power-down retention function. What's more, it supports multiple frequency settings: digital setting, analog setting, PID setting, RS485 communication setting,ect. 【How to Connect Spindle Motor and VFD】The spindle motor's aviation plug marked with number 1, 2, 3, 4. Number 1, 2, 3 port are connected separately with inverter's port U, V, W. Number 4 is the ground wire, no wiring is required., Weight: 13.22773572 pounds, Manufacturer: RT
