The miniature motor commutator experienced blood cutting and blood cutting. We have learned that this situation may be caused by a malfunction of the fan, hair dryer, light bulb, fan, hair dryer, fan, hair dryer, or even high-temperature corrosion of the commutator.

A commutator is a component on a DC permanent magnet series motor that allows the motor to continuously rotate. Structurally, the commutator is composed of several contact plates enclosed in a circular shape, which are connected to each contact on the rotor. The two electrodes connected on the outer side are called brushes and come into contact with them.

What are the reasons for the malfunction of the DC motor commutator? How should we handle the grounding problem of the commutator.

The enameled wires used in AC commutator cars have excellent corrosion resistance, heat resistance, and high requirements for solid-state magnetic fields, which need to meet various electrical or mechanical performance requirements.

In the field of electric vehicles, we use a lot of commutators because the materials used for commutators are carbon, aluminum, and stainless steel, which leads to a relatively high price for commutators.

Many machines also use carbon steel as the material, so it is not difficult to purchase commutators. Many machines, as well as high-temperature resistant graphite sliding bearings, also use carbon steel.

Generally speaking, DC motors only have commutators. The commutator is an important component of a DC motor and its function. Convert the direct current passing through the brush into alternating current inside the winding or convert the alternating electromotive force inside the winding into direct electromotive force at the brush end. In addition, it is important to understand the structure of the electric motor. The commutator is a component on the DC permanent magnet series excitation motor that allows the motor to continuously roll.

The principle of a commutator is that when a coil passes through an electric current, it will rotate under the action of a long-term magnet through attraction and repulsion. When it turns to balance with the magnet, the contacts on the commutator corresponding to the originally energized wire will separate from the brush, and the brush will be connected to the contacts corresponding to the group of coils that generate the driving force. This keeps repeating, and the DC power idea will turn.

If there is no commutator, the motor will only get stuck within half a turn and can only be used as an electric brake.
