Core Tip: stepper motor inside the core and windings are composed. Windings resistance, electricity use will produce some heat. In fact, it is like engraving machine spindle motor, as the temperature is constantly rises, but the spindle motor with a cooling water circulation to reduce heat generation.

Stepper motor inside the core and windings are composed . Windings resistance , electricity use will produce some heat . In fact, it is like engraving machine spindle motor , as the temperature is constantly rises , but the spindle motor with a cooling water circulation to reduce heat generation. But the stepper motor is no water cooling , how to determine its overheating problem yet.
The answer is very simple. A reasonable range of stepper motor heating , electrical heating allows to what extent , depends on the motor internal insulation levels. Internal insulation properties at high temperatures ( above 130 degrees ) will be destroyed. So long as no more than 130 degrees inside , the motor will not be damaged. The internal temperature we may not be able to accurately measure , but we can measure the surface temperature of the motor. When the internal temperature of 130 degrees, about 90 degrees in the outside . Therefore , the surface temperature of the stepping motor is normally 70-80 degrees . Simple temperature measurement method is useful to point thermometer , you can roughly determine: a hand can touch more than 1-2 seconds , not more than 60 degrees ; hand can touch, about 70-80 degrees ; drip a few drops rapidly gas of the above is 90 degrees out.
Stepper motor temperature is too high will cause dislocation occurs CNC engraving machine during normal operation . So after the machine is best to run continuously for several hours to allow the machine a short break
