Explain the operation of the rotary-armature type of ac generator
What will be an ideal response?
The armature is in the rotating assembly, which is used in smaller ac generators. As the rotor spins through the magnetic field provided by the stator, power is generated. It is removed through slip rings and brushes to the output terminals. The practical rotating armature generator has many pole pairs, with opposite poles located next to each other and a complete sign wave is generated as it passes each pair of poles.
