Dear Learner,

It mainly consists of three main parts, i.e. magnetic field system, armature and commutator and brush gear. The other parts of a DC Generator are magnetic frame and yoke, pole core and pole shoes, field or exciting coils, armature core and windings, brushes, end housings, bearings and shafts.
In d.c machine the armature rotates, a voltage is generated in the coils. this generated voltage is called d.c. machine emf. In case of a generator, the emf of rotation is called the generated e.m.f. and Er = Eg . In case of a motor, the emf of rotation is known as back e.m.f. (or counter e.m.f.) and Er = Eb .

emf equation of dc machine is given by (NPØZ)/(60A)
