The main reason for the brushless dc motor spark a
there is commutation spark causes a variety of, must be in numerous factors, find the main reason, can discharge fault, improve the reversing. Check out the commutation deterioration reason. Usually said reversing conditions normalize check and adjustment, is commonly used in dc motor commutator accident treatment method, dc brushless motor factory in dongguan, its principle is as follows.
in a dc motor was put into operation or in the operation of the past, the reversing has been is normal, but in the later operation process, yuntai motor, gradually deteriorate or sudden deterioration, motor before reversing deterioration, the sliding contact, the motor structure and various parts work is normal.
in the process of the motor running, some parts working condition changed, or the environment changes, which destroyed the sliding contact, changed the normal state of reversing, and lead to the deterioration of the reversing. If on these factors, which affect the motor commutator to conduct a comprehensive inspection and adjustment, make its can restore the original normal state, the reversing can be back to normal.
the reversing test for normalization is dc motor for reversing the cause of the accident and troubleshooting methods, dongguan eppo unmanned aerial vehicle (uav) motor, it includes the following main items:
1. Resistance measurement between commutator piece
2. Commutator pendulum to measure
3. Brush the neutral surface check
4. Brush pole pitch, drama and crack inspection and adjustment
