Popis: The paper analyses the performances of a three-phase synchronous generator with an inset neodymium-iron-boron permanent magnet rotor. This rotor structure produces an inverse saliency effect meaning the quadrature-axis reactance is greater than the direct-axis reactance. As a result of this effect, the generator presents itself a voltage compensation capability for maintaining almost constant output voltage at different loads. The paper presents some characteristics and performances computed with FEM and highlight the benefits of this kind of generator for the applications when the generator need to keep almost constant output voltage irrespective of load current.
