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.

Cuvinte cheie: motoare cu reluctanta variabila, metoda elementului finit, unghi intern, 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.

Keywords: reluctance motors, finite element method, load angle, electromechanical cycle
