1) 2.2KW ER20 Air-cooled Spindle motor Engraving milling Grind  1. Structural features 1) High speed electric main bearing all adopt the C-class high-speed angular contact ball bearing, axis sets of loading, Improve spindle in the high-speed rotation supporting stiffness and precision grinding. 2) Before driving, rotation of the shaft by hand.Spindle high speed rotation caused by temperature rise, use of cooling liquid circulating system to eliminate.
2.Maintenance and Service 1) Motorized spindle by medium frequency power supply rated voltage, frequency should be consistent with electric spindle technology parameters, motorized spindle rotational speed can change the frequency to adjust, also directly proportional voltage change.
2) 2.2KW VFD Inverter 220V
◆Two speed control modes: no PG vector control (SVC), V/F control ◆ No PG vector control (SVC): starting torque 0.5Hz up to 150% ◆ 8-stage simple PLC function, multi-speed control and PID control ◆ Support multiple frequency settings: digital setting, analog setting, PID setting, RS485 communication setting ◆ I/O terminals can be freely programmed to combine multiple working modes according to user needs. ◆ With jump frequency control function, it can effectively suppress mechanical resonance and make the system more stable and reliable. ◆ With instantaneous power-down retention function, it can avoid the impact of production due to instantaneous power failure ◆ With over torque and under torque detection ◆ Automatic voltage adjustment function to effectively solve the low frequency oscillation problem of high power motor ◆ 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
