  Direct current generations and their applications

  The Essential difference between a d.c. generator and a. c. generator is that the former has a commutator by means of which the generated e. m. f. is made continuous, i. е., the commutator mechanically rectifies the alternating e. m. f. so that it is always of the same polarity. This is not, however, the only difference between them.

  A d.c. generator as well as a motor of conventional type is made up of the following parts: outer frame, or yoke, pole cores, pole coils, armature windings, commutator, bruches, and bearings. Of these, the yoke, pole cores, armature core and the air gap between armature and pole core form the magnetic circuit while the pole coils, armature windings, commutator, and brushes form the electric circuit.

Generator fields may be either of two main types-separately excited or self- excited. The self-excited type is further, classified as series-wound, shunt-wound and compound-wound. In general practice compound-wound machines are used.
