Generally speaking, only DC motors have commutators.
Commutator is an important component of DC motor. Its function is to convert the DC current passing through the brush into AC current in the winding or convert the AC electromotive force in the winding into DC electromotive force at the end of the brush.
In addition, it should be understood that the structure of the motor commutator is a component of the DC permanent magnet series excited motor in order to make the motor continue to roll.
An important component and function of DC motor --- convert the DC current passing through the brush into the alternating current in the winding or convert the alternating electromotive force in the winding into the DC electromotive force on the brush end. The commutator undercutting machine is used for the undercutting of armature commutator slots such as automobile motor, motorcycle starting motor, electric tool motor and micro special motor Put an armature into the positioning seat, start the switch to automatically jack up, and the machine will automatically align the slot position, undercut and graduation until the undercut is completed and automatically loosen the jack up device Then, the operator removes the armature and puts another armature in the positioning seat, and starts the cycle again The characteristic commutator is a component on the DC permanent magnet series excitation motor in order to make the motor continue to roll.
