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.

Commutators are low impedance devices with low losses on DC rare earth permanent magnet series excitation motors, which need to be considered from structural analysis, small winding deformation, and other aspects.

A commutator is a variable frequency AC motor with low impedance on a DC permanent magnet series excitation motor. Structurally, the commutator is composed of several contact pieces enclosed in a circular shape, which are respectively connected to the forward direction of the commutator.

A copper sleeve slot commutator, commonly known as a commutator, is a component on a series excited motor that allows the motor to continuously rotate.

Commutators include: mechanical commutators, semi plastic commutators, and fully plastic commutators. The commutators used on automotive starters mainly use mechanical arch commutators and plastic commutators.

The principle is that when a coil passes through an electric current, it will rotate under the action of a permanent 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 be separated 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 motor will start to rotate. The purpose of the electric motor.

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< Eod>.
