The armature of a DC motor and an AC rectifier motor is an important component. The motor has a reversing effect when it rotates. It is a component used for current commutation in DC motors and AC series excited motors, commonly known as a rectifier, to ensure the continuous rotation of the motor.
As an indispensable basic equipment in industry, transportation, national defense, and daily life, the downstream industries of motors include almost all basic industries of the national economy. As one of the core components of motors, the commutator is also growing with the development of the motor industry.
Commutators include mechanical commutators, semi plastic commutators, and all plastic commutators. The main commutators used on automotive starters are mechanical arch commutators and plastic commutators.
Hook type commutator (8 pieces, 10 pieces, 12 pieces, 14 pieces, 16 pieces, 18 pieces, 20 pieces, 22 pieces, 24 pieces, 26 pieces, 28 pieces, 30 pieces, 32 pieces, 34 pieces, 36 pieces, 38 pieces, 40 pieces)
Slot type commutator (8 pieces, 10 pieces, 12 pieces, 14 pieces, 16 pieces, 18 pieces, 20 pieces, 22 pieces, 24 pieces, 26 pieces, 28 pieces, 30 pieces, 32 pieces, 34 pieces, 36 pieces, 38 pieces, 40 pieces)
In addition, there is an electronic commutator that uses a wet reed switch. Regardless of the type of commutator, the spark circuit must be indirectly extinguished at the contacts to protect the contacts and reduce interference with the measuring track.
Structurally, the commutator is composed of several contact pieces forming a circular shape, which are respectively connected to each contact on the rotor. The two electric brushes connected to the outside are called electric brushes, and only contact two of them at the same time.
