Synchronous Generator Construction | Parts

A three-phase synchronous generator has three identical windings. Every phase winding is displaced at 120 o electrical apart. When a magnet (rotor) is rotated using some prime-mover in these windings, the stator conductors are cut by the magnetic field of the rotor. Hence an EMF is induced in each winding.

Three phase AC generator

In the simplified construction of three-phase AC generator, the armature core has 6 slots, cut on its inner rim. Each slot is 60° away from one another. Six armature conductors are mounted in these slots. The conductors 1 and 4 are joined in series to form coil 1. The conductors 3 and 6 form coil 2 while the conductors 5 and 2 form coil 3.
