By looking at which particular part of the motor we can Identify a “DC motor”?
By looking at which particular part of the motor we can Identify a "DC motor"?
Right Answer is:
- The commutator converts the alternating current generated in armature into the unidirectional current.
- It is a mechanical rectifier, so the commutator collects induced EMF or current developed in the armature.
- In the DC motor, the commutator is used to alternate the magnetic field created by the DC current.
- For AC motor the magnetic field is already alternated by the nature of the AC current.
