Net friend to ask: why is my CNC engraving machine high temperature, electric opportunity not bad ah, how should I do?
Yifan reply: hello.
Don't know you say how high temperature, if internal above 130 degrees Celsius, the motor must be broken.
If below 130 degrees, it is generally not bad.
A simple judgment method, is to drop a few drops of water surface in the motor, if evaporates quickly, it needs to pay attention to.
