Question
what is the function of commutator in dc motor?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 21
commutator is a mechanical rectifier which converts ac to dc.
when a voltage is generated in armature coils which is ac ,commutator converts it in dc with the help of brushes in gives dc voltage or current.
commutator is always rest on shaft and insulated with it.
