Need of commutator in dc generator

WebChuck Yung EASA Senior Technical Support Specialist There are times when a DC motor or generator experiences a catastrophic failure and the customer wants to know why it happened. One type of failure that seems to stimulate lively conversation is when the failure involves dramatic damage to the brushholders and commutator. The term “flashover” … Consider a commutator consisting of a cylindrical metal ring cut into two segments C1 and C2 respectively separated by a thin sheet of mica. The commutator is mounted on the rotor shaft and insulated from it. The ends of the armature coil sides AB and CD are connected to the segments C1 and C2 respectively. … See more Here, the coil sides AB and CD are under N-pole and S-pole respectively (see the figure). The coil side AB is connected to the segment C1 which is connected to the point x of the load R. and the coil side CD is connected to the … See more After 180° rotation of the loop, the coil side AB is under the influence of S-pole and the coil side CD is under the influence of N-pole (see the figure). Thus, the currents in the coil sides now flow in the reverse directions but the … See more
