When the CNC optical machine works for a long time, the phenomenon of heat will occur. This heating phenomenon is not a good thing for too long. On the contrary, it will affect the service life of the CNC optical machine. Therefore, the overheating protection of CNC optical machines is very important.
Said that when the CNC optical machine generates heat during operation, the heating of the motor windings of the CNC optical machine and the heating of the mechanical rotating bearings are more serious, especially in situations where the ambient temperature is high and the heat dissipation and ventilation are poor, which may damage the motor windings and Rotating bearings. Therefore, we usually use embedded temperature sensors to protect the CNC optical machine motor and rotating bearings from over-temperature operation to extend the service life of the CNC optical machine. When passing a pre-embedded temperature sensor, it should be considered to embed it in the hottest part of the winding and make it in close contact with the part being measured. Protective measures must also be taken to avoid the influence of cold air that cannot accurately reflect the temperature of the winding being measured. maximum temperature.
