WebThe function of a commutator, in a dc generator, is to collect the current generated in armature conductors. Whereas, in case of a dc motor, commutator helps in providing current to the armature conductors. A commutator consists of a set of copper segments which are insulated from each other. WebDC machine –producing the field There are three main electrical arrangements to consider if the fieldis being produced electromagnetically (that is, by a current in awinding): • Series connection • Shunt connection • Separately-excited connection DC machine –producing the field Nb.: There are also several possiblehybridconnection arrangements.
