Construction of DC Machines

Construction of DC Machines slot wedges in dc machine made of Commutator: the commutator is of cylindrical in shape and is made up of wedge-shaped high conductivity hard drawn copper segments These segments are insulated slot spoon FRPEpoxy wedges are used in slots of ELectrical Motors due to their high electrical insulating properties FRP or Epoxy wedges can be made to order according
