Smoke failure or too hot for wholesale Brush DC motor
Treatment of smoke failure or too hot temperature of DC motor:
The DC motor may cause the internal temperature of the DC motor to rise or even smoke when working in a long period of time, in a high temperature environment, or when the internal components of the motor fail. Do not panic in such a situation. In order to be safe and deal with motor failures, we must pay attention to the following points:
1, the power supply voltage of DC motor is too high, so that the core magnet passes through saturation and causes the motor temperature to rise too high: If the power supply voltage exceeds the standard, it should be solved with the power supply department.
2, the power supply voltage is too low, the motor temperature is too high under the rated load: if the voltage of the power line is too large, the thicker power line can be replaced; If the power supply voltage is too low, you can contact the power supply department to increase the power supply voltage.
3, burning the line, the iron heart was cauterized, so that the iron consumption increased: do iron heart inspection tests, repair iron heart, troubleshooting.
4, fixed rotor iron phase rub: check the cause of failure If the bearing gap is too limited, should replace the new bearing, if the shaft is bent, it needs to be investigated and handled, iron core loose or deformation should be handled, to eliminate the failure.
The surface of the winding is covered with dirt or foreign matter, which affects the heat dissipation of the motor: cleaning or cleaning the motor, and making the ventilation ditch of the motor smooth.
The above five situations are the reasons for the failure of the DC motor due to the high temperature encountered daily. It is hoped that some problems of high DC motor temperature can be solved in the daily work production, and some losses and safety problems can be avoided.
