Synchronous generators are responsible for practically all electrical energy used in the world and in general, the composition of the generators depends on the type of machine. Synchronous generators have:
– Stator – The casing is of calendered steel and the package with its respective winding plates are on its ribs;
– Rotor – Accommodates the field winding, whose poles are made up of bundles of plates.
– Main exciter stator and rotor and rotating rectifier diodes.
– Auxiliary exciter and auxiliary coil;
– Nameplate – Contains the data with the nominal characteristics of the generator.
– Paint: background paint, applied by immersion and final paint, finished after the complete assembly of the machine, it is a varnish coat of synthetic enamel applied with a gun. X718-3A-30M
In relation to the synchronous generators, we can emphasize some characteristics for understanding: the synchronous machine is an electrical equipment, with double excitation, where in the armature or armature (usually the stator) circulate alternating balanced currents, forming a rotating field, that is, lagged currents in time travel spatially lagged coils.
The inductor or field is excited by direct current, forming an electromagnet. The two fields must rotate at the same speed so that a nonzero mean torque is obtained.
