Product Details
- ✅【RTM120x103-30-24Z/4.5 220V】Voltage: 220V; Maximum speed: 24000RPM; Rated frequency: 800HZ; Electric current: 15A; Motor pole: 4P; Rated power: 4.5KW (S1); Peak power: 5.4KW (S6); Rated torque: 3.5Nm; Peak torque: 4.2Nm.
- ✅【Technical parameters】Spindle blowing dust/seal gas pressure (MPa): 0.2-0.25; Spindle gas seal gas flow (L/min): 65±10 (When on Working); Cooling air pressure (MPa): ≧0.25; Cooling air flow (L/min): ≧2.5; Spindle static state pulse (µm): ≦3; Spindle vibration (mm/s): ≦1.0; Spindle assembly method: Bottom mounting(6-M8); Motor windings Pressure test (V/M): 1000V/1 minute withstanding Voltage test.
- ✅【By the inverter control】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.
- ✅【Air cooling methods】This spindle uses air cooling to cool the motor and front and rear bearings. The wind is supplied by the fan at the rear end, from the rear end of the main shaft through the inner and outer air slots directly to the front end of the main shaft, thereby taking away the heat generated by the high-speed rotation of the main shaft, achieving thermal balance, and keeping the temperature of the electric main shaft constant within a certain value.
- ✅【Air sealing control】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.
