The Importance Of The Commutator

The commutator is the most important and complex component of DC motors and AC commutator motors.

In the operation of the motor, the commutator has to withstand the effects of centrifugal force and thermal stress, and can not be loose and deformed. Therefore, the working surface of the commutator is required to be smooth and flat, has high wear resistance, heat resistance and arc resistance, and has reliable ground insulation, inter-chip insulation and creepage distance, and has sufficient strength and rigidity. Inter-chip pressure to ensure stable operation of the motor under start, brake and overspeed conditions. In short, the quality of the commutator has a great impact on the running performance of the motor.
