All other parts except brushes and commutator are same in AC machine when outer looks are only taken in consideration. Commutator is used only in DC machine for providing mechanical rectification and not in AC machine.

DC Motor and AC Motor
DC motor and AC motor are two different types of motors used for converting electrical energy into mechanical energy. A DC motor converts direct current electrical energy into mechanical energy while an AC motor converts alternating current electrical energy into mechanical energy.
Identifying DC Motor
To identify whether the given motor is a DC motor or an AC motor, we need to look for certain components within the motor that differ between these two types of motors. One such component is the commutator.
Commutator
A commutator is a component that is present in DC motors but not in AC motors. It is a rotating switch that connects the stationary brushes to the rotating armature of the motor. The commutator is responsible for reversing the direction of the current flow in the armature windings, which in turn causes the armature to rotate continuously.
Therefore, if a motor has a commutator, it is a DC motor. If it does not have a commutator, it is an AC motor.
Conclusion
In conclusion, the commutator is the component that will surely tell us whether the given motor is a DC motor or an AC motor. If the motor has a commutator, it is a DC motor. If it does not have a commutator, it is an AC motor.
