Stepping drive mute _60 stepper motor company
2. Stepper motor fever fever allowed to what extent the reasonable range of motor, mainly depends on the internal motor insulation class. Internal insulation at high temperature ( More than 30 degrees) Will be destroyed. So as long as within less than 30 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 - by hand More 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.
3. Stepper motor heat change with speed using constant current drive technology, the condition of the stepper motor under static and low speed, the current will remain relatively constant, to maintain constant torque output. High speed to a certain extent, the motor internal counter potential, current will gradually decrease, the moment will decline. Therefore, because of the copper loss of fever is related to the speed of the story. Generally high fever when static and low speed, high speed low fever. But the iron losses ( Although the smaller percentage) Situation does not change, but the motor of the fever is the sum of the two, so the above is just normally.
4. heat while generally will not affect the life of the motor, for most customers don't need to ignore. However, serious fever can bring some negative effects. Internal parts such as motor thermal expansion coefficient of different lead to the change of structural stress and internal air gap of tiny change, affects the dynamic response of the planetary gear motor, high speed will be easy to out of step. And as some situation does not allow excessive heating of the motor, such as equipment and testing equipment, etc. So the control of the heating of the motor should be necessary.
