Malfunctions and repair of the motor anchor lamellas

In this way, check all the windings. If the resistance value in each circuit is the same or differs very slightly, the unit is in good condition.
You shouldn’t immediately take it to be repaired or throw away a “broken” device, as many people prefer to do.You will save money if you know how to restore the electric motor collector yourself. The process is not too complicated and does not take much time, and the mechanism will be able to serve for a long time.


The anchor is the moving part of a DC electric motor, on which its entire operation largely depends. Anchor failure can be caused by mechanical damage, violation of operating rules, power outages, and wiring faults.

DC motor anchor
Repair of traction electric motors is required in the following cases:
The brushes are not pressed firmly against the commutator, which does hong kong telegram data not ensure proper contact between them and can cause a short circuit.
The material of the brushes used does not correspond to the type of the collector, which is why they come into dissonance. Very often, electric motors fail precisely because their components are selected incorrectly.
Increased beating of the collector on the armature shaft during rotation.
Broken armature winding, short-circuited turns in the winding.
The resistance between the armature winding and its core is too low/high, does not correspond to the norm. The operation of the engine largely depends on the resistance, so any deviation from the norm can adversely affect the performance of the device.
Short circuits.
Wiring fault.
You should not attempt to repair the electric motor shaft or the entire anchor at the same time on your own - it is better to trust a professional who has the necessary experience and special equipment.

Stages of repair of an electric motor anchor
Repair of the motor armature lamellas consists of several stages, each of which must be performed in a specialized service center using professional equipment.
