The heat of mini brushless planetary geared electric motor is normal in use, but there is a certain control range. Some users find that there is a problem on the feeling of fever, in fact, the cause of fever we can understand from several aspects.

mini brushless planetary geared electric motor Heating 70-90℃ is a normal phenomenon, as long as it is less than 130℃, there is generally no problem, if you really feel overheating, Set the current of the driver to about 70% of the rated current of the motor or reduce the speed of the motor. When there is no fault, it will normally heat up. Of course, the normal heating temperature is not too high.

mini brushless planetary geared electric motor normal heating causes:

First, the coil has resistance, current flow loss power;

Second, the magnetic field of the iron core has a "hysteresis loop", and a part of the magnetic energy of the electrical energy transformation continues to be transformed into heat energy;

Third, there is eddy current in the iron core, and part of the magnetic energy converted by electric energy becomes current and then becomes heat energy;

Fourth, there is friction between the mechanical rotating parts, and a part of the kinetic energy of the electrical energy transformation continues to be converted into heat energy.

Understanding the cause of mini brushless planetary geared electric motor heat, we can control it reasonably. If the temperature exceeds the normal range, the work should be stopped in time, the corresponding inspection work should be made, and the treatment should be done.
