What Are The Functions Of Sliprings In A DC Motor?
Answer:
Most DC motors do NOT have slip rings, they have brushes. The brushes, which are stationary, job is to rub against the commutator. The commutator is a ring (you may enjoy thought this was a slip ring) that is split into segments. Opposed pairs of the comutator segment are wired into electro magnets located in the rotating armature which is the part that spins.
So when the brushes connect to a pair of commutator segment a particular electromagnet on the armature turns on and pulls the armature a little to turn it. But as the armature turns the brushes loos contact with that set of commutator segment and that magnet looses power and goes off. Then, as the armature and commutator turns a different set of segments attached to a different electro magnet repeats the process, the armature keep turning...
