The principle of of the stepper motor generating heat:

  The various types of motors we usually see are iron cores and winding coils inside. There are resistance in the winding, and some energy would be converted to heat, the loss is proportional to the square of the resistance and the current. If the current is not a standard DC or sine wave, it will also cause harmonic losses; the iron heart has magnetic stagnation The vortex effect will also cause losses in the cross -magnetic field. The size is related to the material, the current, the frequency, and voltage. This is called iron loss. Copper loss and iron loss will be manifested in the form of heat, which affects the efficiency of the motor. Stepping motor generally pursues positioning accuracy and torque output. The efficiency is relatively low, the current is generally large, and the harmonic component is high. 

The harm of the stepping motor overheating:

  Although the heat generated by the stepper motor generally does not affect the life of the motor, but in severe cases, overheating would impact the performance of the stepper motor. For example, the different thermal expansion coefficient inside the motor causes changes in the structural stress and the small changes in the internal air gap will affect the dynamic response of the motor, and it will be easy to lose. Another occasion is not allowed to be excessive fever in the motor, such as medical devices and high -precision testing equipment. Therefore, the heat of the motor should be controlled.

  As we know the overheating is harmful for the stepper motor, but how to cool down the stepper motor to make it work normally? Usually we need to design a heatsink for cooling. Stepper motor heat sink is usually made of aluminum alloy due to the power of stepper motor is not very high, so a aluminum extruded heat sink can satisfy the thermal requirements, and the surface finish is usually anodizing, the color can be customized.
