7.5 kW Water Cooled CNC Spindle Motor, 24000 rpm, ER32
Brief
Description
High quality 7500 watt three phase water cooled CNC spindle motor, works at 3 phase 380V AC 400Hz, 24000rpm, 2.98N·m torque with ER32 (φ3.175mm - φ20mm), suitable for CNC router machines.
Feature
- Spindle motor with superior durability ER32 collet ensures smooth running.
- Fast response, strong overload capacity, low noise and high mechanical precision.
- High quality 4 pcs bearings (7007Cx2 + 7005Cx2), 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.
Applications
This series water 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: Why use VFD for spindle motor?
- A VFD can make the motor soft start, and the impact on mechanical equipment is small.
The starting current of the VFD is smaller than that of the contactor, and the more frequent the working condition, the more energy-saving. - It can be infinitely variable, and it is easy to meet the work requirements of elevators and other requiring smooth speed.
- Convenient for automatic control. The VFD has external control and local control, and can be selected at multiple speeds. With an encoder, the spindle motor can be accurately positioned, and the control is very portable.
- The internal protection is perfect, and variable frequency drives are equipped with various fault protection functions. When the spindle motor or power supply fails, it will actively report the fault, and at the same time output the on-off signal through the relay contact, which is convenient to cut off the external control contactor and output the warning signal.
