“…In recent times, a method for terminal voltage adjustment in a self-excited synchronous generator has been proposed in [27], while an experimental investigation on its loading characteristics and output voltage harmonics has been presented in [28]. Moreover, the causes of asymmetric torque generation in self-excited synchronous motors, which utilize space MMF harmonics, have been deeply investigated in [29], and the impact of load and speed variation to frequency variation on single-phase self-excited induction generator has been described in [30].…”

Today, self-excited synchronous machines are the object of increasing interest because they use neither brushes nor permanent magnets. In fact, the price of rare earth metals is considerably high and still raising. This is the main reason why researchers are looking for suitable alternatives to permanent magnets in the construction of rotating electrical machinery. This paper deals with the design and laboratory testing of a synchronous machine with an efficient layout and an economic construction. The proposed self-excited machine exploits the space harmonics of the magneto-motive force to produce the excitation field. The model analysis is based on the computation of the back EMFs that are associated to the magneto motive force components. The mathematical model suggests an easy way to decouple the rotor windings. The machine has been built and experimental tests have been performed in order to validate the electrical behavior.
