RATTMMOTOR CNC Spindle Motor Kit Square 2.2KW 220V Air Cooled Spindle Motor ER20+2.2KW Inventer VFD 220V Variable Frequency Drive Converter Speed Control for CNC Router Engraver Milling Machine

About this product

*【Package Include】: ①1 x 2.2KW Square Air Cooled Spindle Motor ②1 x 2.2KW VFD with cable ③1 x ER20 Wrench

*【2.2KW Spindle Motor】: ①This is a 220V-2.2KW air-cooled 6A spindle motor come with a ER20 nut and collet. Frequency is 400HZ, precision tapered bore is less than 0.005mm and runout off is Less than 0.01mm. ②Speed of The Spindle Motor : 0-24000RPM. Because it is a high-speed spindle motor, the spindle speed must not be lower than 9000 rpm during the use of the spindle. It should be noted that the main shaft cannot only rotate clockwise or counter-clockwise.

*【2.2KW VFD】①Parameters: Input Voltage: 220V(+/-15%), Output Voltage: 220VAC, Input Frequency: 50-60 Hz, Output Frequency: 0-1000 Hz, 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.

*②Other 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. Whats 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 motors aviation plug marked with number U, V, W. Number U, V, W port are connected with inverters port U, V, W respectively.
