Prądnica synchroniczna z magnesami trwałymi o podwójnym wirniku zwiększajaca częstotliwość generowanego napięcia

This paper presents the construction of a model, two-stage low speed synchronous generator designed for producing energy from the renewable sources. Moreover, the computational methodology and the basic results of electromagnetic calculations of the two-stage low speed synchronous generator with permanent magnets are presented. On the basis of the calculations conducted, a physical model of the generator was made, on which the preliminary laboratory tests were carried out. There is also a comparative record sheet of the preliminary laboratory tests and the results of the theoretical calculations included in the paper.
