How to solve the problem of overheating during the operation of DC motors

　　1.High power supply voltage:The high power supply voltage of the DC motor leads to oversaturation of the magnetic flux density through the core,resulting in excessive current and heat generation.At this time,a suitable power regulator should be installed or the power supply department should be sought for a solution.
　　2.Low power supply voltage:Low power supply voltage can also cause heating.If the voltage is too low,the operation of the motor is very unstable,which can easily cause fluctuations in operation and cause heating.At this time,we should contact relevant departments in a timely manner to increase the power supply voltage.
　　3.Iron core malfunction:The iron core has a malfunction that causes iron loss,damage,and heating.At this time,we should inspect the iron core and eliminate the problem.
　　4.Friction between the stator and rotor cores:The bearing clearance of the DC motor is abnormal,causing increased friction and overheating during operation.We need to promptly inspect the bearings for abnormalities and replace bearing accessories if necessary.
　　5.The surface of the winding is covered with dust or foreign objects,which affects the heat dissipation of the motor:Clean or clean the DC motor and ensure that the motor ventilation duct is unobstructed.
　　6.Motor overload:Motor overload causes excessive current in the motor,resulting in overheating during operation.At this time,it is necessary to replace the large capacity motor or increase the motor capacity in a timely manner.
　　7.Motor starting problem or excessive number of forward and reverse rotation:Frequent starting of the motor can lead to an increase in instantaneous current,causing the motor to heat up,while frequent alternating operation of forward and reverse directions can cause abnormal motor operating speed and motor heating.This situation is usually due to hardware issues with the motor,and we need to replace it with a new one.
