Principles and Working of DC and AC machines

When a dc voltage is applied to the field windings of a dc generator, current flows through the windings and sets up a - - steady magnetic field. This is called FIELD EXCITATION. This excitation voltage can be produced by the generator itself or it can be supplied by an outside source, such as a battery. DC Machines

Construction of dc Machines

Construction of dc Machines: The rotor in a dc machine is called an armature. The armature has cylindrical steel core that is composed of a stack of slotted laminations. Slots in laminations are aligned axially along rotor or shaft. Armature windings are placed in slots. The stator in a dc machine is the field part of the machine.
