7.5KW BT30 ATC automatic tool change Air Cooled Spindle Motor 220V with 7.5KW VFD Inverter 220V Package include: 1 x 7.5KW ATC Automatic Tool Changer Air cooled spindle motor 220V (BT30 800hz 24000rpm)1 x 7.5KW Fuling brand Inverter VFD 220V1 x BT30-ER25-70L Tool Holder with 45 degree pull stud2 x Air plugPdf. English user manual Dimension Features: 1.This spindle is built-in type spindle motor, built-in three asynchronous motors,by the inverter control.As the spindle has a compact structure,high power, big torque, small vibration, low noise characteristics,so it can achieve high speed,high powe cutting,high recision and high stability operation. 2.The bearing of spindle use grease lubricated angular to contact bearings. 3.This spindle uses air cooling to cool the motor and front and rear bearings. The wind is provided by the fan at the rear end, from the rear of the spindle through the inner and outer air slots directly to the front of the spindle, there by taking away the heat generated by the high-speed rotation of the spindle, achieving thermal balance. 4.The spindle built-in PTC 140 temperature sensor. 5. The tool clamping methods:this spindle built-in automatic tool change device,tool holder form is BT30. 6.Sensor Model (0-24V, PNP) The spindle built two sensors.wiring Diagram is as follows: Response tool clamp signal, when the tool holder is hang, black sensor output signal;Response tool open signal, when the tool jaws open,black sensor output signal. 7.5KW ATC Spindle Parameters: Model Number: RTM120x103-30-24/7.5Maximum Torque : 7.2N.mRated torque : 6N.mRated Speed: 12000RPMMax Speed: 24000RPMMax. Frequency: 800HzVoltage : 220VBearing : 4 bearings(2x7008 and 2x7006)Nose : BT30Motor pole : 4 PoleCurrent:12ADefend grade: IP53Insulation grade:F Spindle installation explanation 1.Fan cooling system description When the spindle rotates, the rear fan system must be started to ensure the correct supply voltage and the supply voltage is 12V. 2.Air sealing control (AS) In order to prevent water or impurities enters internal of the spindle,spindle will have gas sealing device,the gas seal machine must be started start with the machine at the same time. And the need to go through multi-stage filtration. 3.Compressed gas quality requirements The quality requirement of gas which is used in gas seals: Oil content：﹤0.01mg/m³ solid particle：﹤5µ m Pressure dew point：﹤7.5℃（0.7MPa） 4. Running-in program instructions Only all monitoring issued no failures operational signals,at the same time,all safety devices have been installed and working properly,then allow start spindle. Note: new or spindle which is not used for a long time must to be running slowly.First,start run spindle for half an hour as 25% of the maximum speed,then increase to 50% of the maximum speed,to run 15 minutes,finally,increase to maximum speed. Inverter Parameters: 7.5KW VFD Inverter 220VInput Phase: 1 phase or 3 phaseInput Frequency: 50-60Hz (±5Hz)Output Voltage: 220VOutput Phase: 3 phaseOutput Current: 31AOutput Frequency: 0-1000HzControl Method: V/F control Notice: PLS notice all parameters of the inverter are pre-set before leaving the factory,so you can directly use it to run the spindle,no need to set up the inverter.And to avoid damaging the inverter,PLS DO NOT set up the inverter by yourself if you don't know how to. Wiring: R S T any 2 pins connect to 220V AC power supply,we will recommend connect R & T 2 pins to 220V AC power supply Two speed control modes: 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 failureWith 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.
