How To Maintain And Repair The Brush Motor Commutator?

A common problem with brushed motor motors is a common failure of the carbon brushes and commutator. In addition, there are also failures, abnormal operation, too fast, too slow, strange noises, sparks, etc. Damage to the carbon brushes of a brushed motor will cause the motor to terminate, and the carbon brushes should be replaced. The failure of the commutator will cause the motor to be exhausted or stop. In serious cases, the gear motor stops and the commutator needs to be replaced. How to maintain and repair the brush motor commutator? The following Vshida micro motor will give you a brief introduction.

Check the degree of damage to the commutator. If the metal sheet on the surface is uneven or short-circuited, a new commutator needs to be replaced. Solder all the connections between the electromagnetic coil and the commutator with a soldering iron, gently open the copper core wire around the commutator with both hands, and remove the commutator. Put the commutator of the same specification into the initial part of the commutator, and weld the start of the electromagnetic coil and the commutator with a soldering iron. Then repair the copper core wire. If the short circuit fault of the electromagnetic coil or the commutation film is more serious, the short circuit and carbon brush vibration are more serious, and sometimes the current is too large, which may cause continuous sparks, too many continuous sparks, and finally become a ring fire.

Repair solution:
① There is oil stain on the surface of the commutator of the transmission gear speed regulating motor, wipe it with alcohol.

②Axial force and deformation of the commutator, the commutator should be replaced.

③The short-circuit fault of the winding of the synchronous motor is more serious.

④ If the mica of the commutator is prominent, it should be notched, rounded and ground.

⑤ The winding of the synchronous motor and the commutation plate are seriously open and welded.

⑥Look for short-circuit faults or interruption points and clear common faults.

The above is the maintenance and repair method of the brushed motor commutator we introduced to you, I hope it will be helpful to you. Please contact us for more information.
