Rezumat
Se trateaza procesul de conversie electromecanica pentru o masina cu reluctanta variabila, unipolara cu flux
axial utilizand analiza prin metoda elementelor finite, MEF. Particularitatea motorului, si anume structura unipolara, este
cea care face ca atunci cand alimentarea se face de la frecventa retelei de 50 Hz, motorul functioneaza la turatia de 6000
rot/min. Pentru o privire mai detaliata asupra procesului de conversie se utilizeaza notiunile de unghi intern si ciclu
electromecanic.

Abstract
The paper presents the electomechanical conversion process for a variable reluctance, single-pole, axial-flux
machine using the finite element method, FEM. The particularity of this motor is ensured by the single-pole structure, which
makes the motor to operate at the speed of 6000 rpm when supplied from a voltage source with the industrial frequency
of 50 Hz. For a clearer insight into the conversion process the notions of load angle and electromechanical cycle are
introduced.
