Brief
Description
2.2kW CNC spindle motor for sale at factory price, 18000 rpm speed, 1.1 Nm torque, 300Hz frequency, 3 phase 380V AC operating voltage, ER20 (φ3.175 mm - φ13 mm) collet.
Feature
- Spindle motor with air cooling fan and ER20 collet ensures smooth running.
- Fast response, strong overload capacity, low noise and high mechanical precision.
- High quality 4 pcs bearings (7005Cx2 + 7002Cx2), runout off less than 0.01mm, tapered bore less than 0.005mm.
- P4 grade ceramic ball bearings used as spindle bearing, which improves the service life under high speed revolution.
- Lubricated with grease, which is resistant to 200 degrees high temperature.
- Tight sealing and two-layer dustproof design.
Application
This series air-cooled electric spindle motors mainly match with variable frequency drives or engraving machines, CNC router machine, and used for high speed profiling, drilling, cutting, engraving and groove milling of wood, metal, plastics, foam, rubber and other materials.
Note: The spindle motor and VFD shall be suitable with each other. The specifications and parameter settings of the VFD shall match the nominal parameters of the spindle motor. Otherwise, it will burn the spindle motor if the settings are not correct.

Tips: 3-step Inspection Before Starting High-speed Spindle Motor
- Check whether the screws of the spindle motor are tightened, whether the bearing is short of oil, whether the wiring meets the requirements, and whether the housing is reliably grounded or zeroed.
- Check whether the screws and pins of the coupling are tight, whether the belt connection is good, whether the tightness is appropriate, whether the unit rotates flexibly, whether there is jamming, movement, abnormal sound, etc.
- Check whether the three-phase power supply voltage is normal, whether the voltage is too high or low, or whether the three-phase voltage pair is asymmetric.
All necessary inspections must be in place. Only in this way can errors in operation be reduced, damage to high-speed spindle motors can be reduced, and the safety of operators should be ensured accordingly.
