No matter what motor in the process of use, will produce a certain amount of heat, DC motor motor is the same, this is a normal phenomenon, but if there is found to be overheating, it should be taken seriously, should be carefully analysed the reasons for overheating, to find a suitable solution. So DC motor overheating, what are the specific causes? What are the solutions?
1. Power supply voltage is high or low, high voltage makes the magnetic flux density saturation, resulting in excessive current, causing overheating; voltage is too low, the motor is unstable, running fast and slow, resulting in overheating, you should find the power supply department to solve the problem, and install the right power regulator.
2. The stator and rotor iron core has problems, resulting in iron loss heat, technical maintenance personnel can overhaul the iron core, troubleshooting.
3. DC motor motor bearing clearance is abnormal, resulting in friction, overheating phenomenon when running, pay attention to timely inspection of bearings, if there is a big problem can choose to replace.
4. Motor operation overload, resulting in excessive current, overheating phenomenon, should be replaced with high-capacity motor.
5. The motor starts frequently or reverses too many times, resulting in increased current, overheating phenomenon, this problem is generally motor hardware problems, it is recommended to replace the new motor.
6. DC motor motor winding coil surface is not clean, there is dirt, affecting the motor's heat dissipation function, resulting in overheating, you can thoroughly clear the dirt and foreign matter, to ensure that the motor runs smoothly ventilated.
As we analysed above , when we are using DC motor motor, if overheating occurs, we must stop the motor running in time, find out the problem and take the appropriate solution!Guangdong Lihua Mechatronics Co.,Ltd Research micro-motor for 20 years, adhere to the quality and strict control of the internal production, support for one-on-one motor design and research and development programmes.
