This paper presents the main features of design, construction, performance analyses and experimental studies of a brushless self-excited three-phase synchronous generator. The basic construction, principle of operation, and exciting characteristics are described. In proposed machine the rotor winding is shorted through diodes and the self-excitation is reached by a slip between rotor and stator winding built with different pole numbers. Computer simulations performed with MATLAB® software were used to verify the mathematical model of the brushless self-excited synchronous generator and the achieved results showed similar behavior with experimental values.
