In the use of brushless DC motor, some friends reflect that the motor is hot, in fact, the motor will be hot, just the normal heat and temperature rise is too high, so why is the brushless DC motor hot? Vacuz give you an introduction to how the temperature is too high!

DC brushless motor why heat?

1. DC brushless motor coils have resistance, there is a certain loss of power when the current passes through, it will generate a certain amount of heat, so the coil winding must be normal.

2. Motor mechanical moving parts have a certain friction, making part of the kinetic energy into heat, causing the motor to heat up.

3. The magnet has a certain eddy current effect, electrical energy and magnetic energy in the conversion, part of the conversion into current, and then into heat, causing heat phenomenon.

4. rotor magnet operation, there is a “hysteresis line” effect, the conversion of electrical and magnetic energy, a small part into heat, causing the motor to heat.

DC brushless motor temperature is too high how to do?

1. Pay attention to check the quality of the winding coil has no problems.

2. motor whether there is a load phenomenon, the need to reduce the load or replace the larger power of the motor.

3. Check the mechanical moving parts, whether the bearings are worn and loose, stator-rotor matching situation.

4. DC brushless motor do not start frequently, the ambient temperature should not be too high, pay attention to smooth ventilation, remove dust and oil, package eat fan normal operation.

Solve the DC brushless motor heating problem, must first figure out the cause of heat, if it is in the normal range, you can observe a period of time, if it is beyond a certain temperature, you need to stop working, make the appropriate inspection work, and do the treatment, so as not to burn the motor spare parts!
