Application

This series of air-cooled electric spindle motors is designed primarily for use with variable frequency drives or engraving machines, as well as CNC routers. It is ideal for high-speed profiling, drilling, cutting, engraving, and groove milling across a variety of materials, including wood, metal, plastics, foam, and rubber.

Note: Ensure that the spindle motor and VFD are compatible. The VFD’s specifications and parameter settings must align with the spindle motor’s nominal parameters. Incorrect settings can lead to spindle motor damage or burnout.

Tips: Cooling Method of CNC Spindle Motor

Engraving machine spindle motors mainly have two ways of heat dissipation: water cooling and air cooling. When the spindle motor is working, high-speed rotation will produce a lot of heat. If the heat is not dispersed in time, it will have a great impact on the service life of the spindle, and the spindle will be burned seriously. Normal heating is a normal phenomenon, if too much heat will affect the performance and life of the spindle motor.

In the process of operation, the engraving machine spindle will produce heat phenomenon, the main reason is bearing damage, lack of bearing grease or bearing is too tight. If it is caused by the bearing of the spindle fever, it is necessary to replace or clean the spindle bearing or add the appropriate amount of grease. When cleaning bearings, kerosene or gasoline is generally used for cleaning, first rough washing and then fine washing, and then evenly coated with high-temperature resistant grease and then reassembled. If the bearing preload is too large to cause fever, first check the bearing before and after, and adjust the gap between the gaskets. The bearing clearance is required to be between 0.08mm and 0.10mm without the external force of the locking nut, and then the nut can be re-locked.
