The commutator segments in the commutator are actually not numbered, but for the needs of bias wiring, and for the needs of technical communication and recording, we number the commutator segments in the commutator, divided into 4 situations.
1. The number of the commutator when facing the right winding
2. The number of the commutator when the right winding is biased
3. The number of the commutator when facing the left winding
4. The number of the commutator when the winding is biased to the right
Because the left-row winding is rare, the most commonly used are the number of the commutator when facing the right-row winding and the number of the commutator when the right-row winding is offset.
Generally speaking, DC motors have commutators.
The commutator is an important part of the DC motor. Its function is to convert the DC current passing through the brush into the alternating current in the winding or the alternating electromotive force in the winding into the DC electromotive force on the brush end.
In addition, it should be understood that the structure of the motor, the commutator is a component of the DC permanent magnet series IP idea in order to allow the electric idea to continue rolling.
An important part of a DC motor, its role --- convert the DC current passing through the brush into an alternating current in the winding or convert the alternating electromotive force in the winding into a DC electromotive force on the brush end. The commutator undercuts the machine It is suitable for engraving under the armature commutator slot of automobile motor, motorcycle starter motor, power tool motor and micro motor. Put an armature into the positioning seat, the start switch will be automatically tightened, and the machine will automatically align the slot. Engraving and indexing until the engraving is completed and the top tightening device is automatically released. Then, the operator removes the armature and puts another armature in the positioning seat, and restarts the cycle. The characteristic commutator is DC permanent magnet A part of the serial IP idea in order to keep the electric idea rolling down.
