construction of phase synchronous machine

Construction of Three Phase Synchronous Machines -

Construction of three phase synchronous machines. An alternator consists of two parts, the stator, and the rotor. The stator is the stationary part of the machine, and the rotor is the rotating part of the machine. The stator carries the armature winding in which the voltage is generated, and the output is taken from it.

Synchronous Machines 1.0 Introduction

2005-12-6  Fig. 5 illustrates the synchronous generator construction for a salient pole machine, with 2 poles. Note that Fig. 5 only represents one “side” of each phase, so as to not crowd the picture too much. In other words, we should also draw the Phase A return conductor 180° away from the Phase A conductor shown in the picture. Likewise for Phases B

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.
