Stepper motor heating allows to what extent, mainly depends on the internal motor insulation class. Internal insulation at high temperature (More than 130 degrees)Will be destroyed. So as long as within no more than 130 degrees, the motor will not damage, while the surface temperature under 90 degrees. So, step motor surface temperature in 70 -80 degrees are normal. Simple useful point thermometers, temperature measurement method can also be roughly judge: can touch 1 - by handMore than 2 seconds, no more than 60 degrees; Can only touch with the hand, around 70 -80 degrees; Drop a few drops of water gasification quickly, more than 90 degrees. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
