Enumerate the Different parts of DC motors and give the functoin of each parts.?
Your question is insufficiently precise. There are currently two types of DC motors, brushed and brushless. A brushless DC motor is actually an AC motor with built-in electronics to do the commutation. In this particular case, permanent magnets are installed on the rotor, and coils on the outside of the rotor are energized so as to push and pull the magnets around in the circle. A brushed DC motor has coils on the rotor and permanent magnets around the periphery. Brushes, actually chunks of graphite make contact with the commutator on the rotor so as to energize the coils to get pulled and pushed by the magnets in the periphery. The commutator, as it spins around makes and breaks the circuit to the coils to cause changing energizations of the coils.
