Alternator And Electric Carbon Brushes

Our organization manufacture and supplier for Alternator and Electric Carbon Brushes in Ahmadnagar Cantonment , Maharashtra , India. For an electric motor or generator to function, the coils of the rotor must be connected to complete an electrical circuit. To accomplish this, (copper or brass) 'slip rings' are affixed to the shaft, and spring spress braided copper wire 'brushes' onto the rings which conduct the current. Such brushes provided poor commutation as they moved from one commutator segment to the next. The cure was the introduction of 'high resistance brushes' made from graphite (sometimes with added copper). Although the resistance was of the order of tens of milli ohms, they were high resistance enough to provide a gradual shift of current from one commutator segment to the next. The term 'brush' has remained in use to this day. As the brushes are slowly abraded, they may have to be replaced, if this is possible.
