for electrical energy to be suppplied to a rotating device such as the armature, some sort of sliding brush contact must be established. Sliding brush contacts are either slip rings or split rings. Slip rings are constructed of a cylinder of insulating material with two separate solid metal rings glued to it. Sliding brushes made of carbon and graphite ride on the metal rings and permit application or extraction of electrical energy from the rings during rotation. The spilt-ring commutator is similar to the silp ring except a solid metal ring is cut into two or more separate sections.As a general rule, slip rings are used in AC motors and generators, while DC machines employ the split-ring commrtating device .The gap or split in the commutator is kept at a minimum to reduce sparking of the brushes.
There are several other parts used in the construction of rotating machines. Among these are the rotor shaft,while rotates between a set of bearings. Bearings may be either the ball, roller, or sleeve type.Bearing seal,often made of felt material,are used to keep lubricant around the bearing and keep dirt out.A rotorcore is usually constructed of laminated steel to provide a low-reluctance magnetic path between the field poles of a machine and to reduce eddy currtens. Internal and external electrical connections provide a means of delivering or extracting
