Synchronous Generator Construction and Working PrincipleThe generator in which permanent magnet is used instead of coil to provide excitation field is termed as permanent magnet synchronous generator or also simply called as synchronous generator. Construction of Synchronous Generator. In general, synchronous generator consists of two parts rotor and stator.Principle & working of Synchronous generator or AlternatorThe stator in the synchronous generator is a stationary armature.This consists of a core and the slots to hold the armature winding similar to the armature of a d.c generator.The stator core uses a laminated construction.It is built up of special steel stampings insulated from each other with varnish or paper.The laminated construction is basically to keep down eddy current losses.

Synchronous Machine Explanation and DemonstrationB. Synchronous machine. The theory of the synchronous machine is well known, so only the basic model characteristics will be described here. A cross sectional view of a 3phase, 2pole, salientpole synchronous machine is shown in Fig. SM1. The stator phases are represented by three sinusoidally distributed windings, displaced by 120 degrees.Synchronous Operation Of GeneratorWhat is the synchronisation? To many people, the operation of a synchronous generator is very mysterious and strange. Here is this huge machine which runs are a constant speed whether the 4 – 24 inch steam valves are wide open or shut tightly the machine speed is constant.
