Six reasons why the Customized 110v dc motor brush spark is too large
When the permanent magnet DC motor is running, sometimes the brush spark is too large. This is a motor fault. Everything is abnormal. Therefore, it is necessary to test the permanent magnet DC motor. Before handling the fault, it is necessary to understand why the brush spark is too Big, the following Longhui motor will talk about the usual experience of using permanent magnet DC geared motor, let everyone know that it is usually caused by the following six reasons.
1. The surface of the commutator is not smooth or the mica sheet protrudes;
2. The DC gear motor brush is not on the neutral line;
3. The rotor dynamic balance is not corrected well;
4. The DC gear motor is overloaded or the power supply voltage is too high;
5. The armature winding or the pole winding or the commutating pole winding is faulty;
6. Improper brush pressure or poor contact with the commutator or brush wear or wrong brush number.
In the future, when the permanent magnet DC motor is used, if the spark is too large, it can be eliminated according to the above situation, quickly find the cause and solve the problem, and avoid the loss caused by the fault.
