D.C series generator

D.C shunt generator

D.C short shunt compound generator

D.C. long shunt compound generator

the generator runs at rated speed

the field circuit resistance is more than field critical resistance

the residual magnetism existing in the field cores

brushes are in proper contacts

providing compensating winding in the main pole faces

shifting brush position from GNA to MNA

providing inter poles between the main poles

using low resistance brushes
