Construction of Synchronous Generator. In general, synchronous generator consists of two parts rotor and stator. The rotor part consists of field poles and stator part consists of armature conductors. The rotation of field poles in the presence of armature conductors induces an alternating voltage which results in electrical power generation.

Basically, an AC generator is an electrical machine that converts mechanical energy into electrical energy in the form of Alternating Current (AC). Basic principle behind the working of an AC synchronous generator is also Faraday's law of electrical induction, somewhat similar to working of a DC generator. How does an AC synchronous generator or alternator work?
