What is AC Generator? Modern AC sources are, almost exclusively, induction generators, where the principle of work is based on electromagnetic induction. In this case, the electromagnetic current is obtained by rotating the conductors in the magnetic field. Today, almost all alternating current generators are three-phase. This means that in their movable part, which is called a rotor, they have three separate coils, placed between each other at an angle of 120◦, in which three EMC are phase-shifted precisely by 120◦, or in time sequence for a third period. Coils are usually indicated by the letters R, S and T, each of which defines a single phase. Depending on the binding of these coils, the transmission of electricity from the generator to the consumer is carried out with 4 or with 3 conductors. If at the beginnings of all the coils are bound at one point (the so-called zero point), then we are talking about star connection. In that case, the other ends of each coil, are connected wit...

What is DC Generator? Contemporary developments are aiming towards eliminating direct current machines such as the DC generator, but they are still extensively used when a very smooth voltage is required, which cannot be achieved by a synchronous alternator with a diode or a network adapter. The basic parts are stator and rotor. The stator is usually made of permanent magnet, while the rotor from soft iron with copper conductors through which the current flows. The current is fed to the rotor via brushes that come across segments of copper. In order to rotate the rotor continuously and not to make a short circuit when the  brush touches two adjacent segments, the rotor must have at least three segments, while usually there are more than 10. The DC current of the stator winding creates a permanent magnetic field. Rotor rotates in this magnetic field and due to dynamic induction, it produces an EMC. All electromotive forces under one pole are in the same direction, and under another ...
