Description: 4.5KW 220V or 380V BT30 Automatic Tool Change ATC Air Cooled Spindle Motor 800Hz 1 x 4.5KW BT30 ATC Automatic Tool Change Air Cooled Spindle Motor 220V or 380V ( 24000rpm,15A,3-phase,800Hz, 4pcs bearing )2 x Aviation plug1 x BT30-ER25 Tool Holder with pull studEnglish user manual will send by emailNote: We have 220V and 380V type for this model, pls leave us message when you order. 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 precision and high stability operation.2) The bearing of spindle use grease lubricated angular to contact bearings,can be achieved lifelong lubricating within the life cycle.3) The spindle use forced coolling mode to coolling motor,front and rear bearings.Coolant flow through the reasonable arrangement cycle watercourse of the spindle body,thus can take the heat generated of the spindle rotation speed, to achieve thermal equilibrium,let spindle temperature within a certain constant value. External cooling device effect:maintaining a constant temperature of the coolant.4) The spindle built-in PTC 140 temperature sensor(Technical parameters are visible in other sections of this specification),you can read it anytime if you need to protect the motor temperature.5) The tool clamping methods:this spindle built-in automatic tool change device,shank form is BT30.

Spindle installation explanation 1) Fan cooling system descriptionWhen 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 requirementsThe quality requirement of gas which is used in gas seals:Oil content: ﹤0.01mg/m³Solid particle: ﹤5µ mPressure dew point: ﹤7.5℃(0.7MPa) 4) Running-in program instructionsOnly 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.It’s need to check the temperature of the spindle during the whole process, spindle will get hot, but not hot hand, if the spindle becomes hot, pls stop the operation and contact our customer service department. 5) Product backend interface instructionsNo.FunctionDefinition1Gas sealing (Protection of impurities into the spindle 0.2-0.25MPa)Ф62Return air (piston reset 0.35-0.45MPa)Ф65Power supply (Spindle power lines with thermistor)U/V/W/ Ground wire6Intake air (Spindle loose knife 0.5-0.6MPa)Ф67Sensor (spindle tool change signals 24V)Broach / loose knife8Fan (spindle cooling)12V 6) PTC140 Temperature coefficient thermistor parametersOur products are equipped with a single thermistor PTC140, it can be used for spindle temperature protection.Parameter nameParameter symbolSingle coreThree core Series connectionUnitMaximum DC working temperatureUmax3030VRated control temperatureTkDesigned according to user℃Rated control temperature toleranceT1±5℃±5℃℃Rated control temperature toleranceT2±0.5℃±0.5℃℃Resistance value on 25℃R25≤100≤300ΩRated control temperature on -5℃ resistance valueTk-5℃≤550≤1600ΩRated control temperature on +5℃ resistance valueTk+5℃≥1330≥4000ΩRated control temperature on +15℃ resistance valueTk+15℃≥4≥12KΩThermal response timeTa≤5≤5SDielectric strengthUisAC2.5AC2.5KVMaximum control temperatureTkmax180180℃Maximum allowable storage temperatureTmax180180℃Minimum allowable storage temperatureTmin-40-40℃ 7) Product Tool Change Signals DescriptionSensor Model (0-24V, PNP), The spindle built two sensors.wiring Diagram is as follows:1.
