Rezumat
Lucrarea urmareste studiul alternatorului cu poli gheara in urma modificarilor constructive, introducerea de
componente din Aluminiu si Cupru, in cadrul rotorului si influentele pe care le produc acestea in modificarea parametrilor
alternatorului, fiind urmarite prin realizarea unor prototipuri practice, care vor sta la baza modelelor ulterioare. O reducere a
pierderilor din histerezis se realizeaza prin reducerea nivelul de saturatie in rotor, puterea economisita fiind transferata in
puterea utila la iesirea masinii, realizand astfel cresterea performantelor.

Abstract
This paper aims to study the claw-pole alternator following some constructive modifications such as the
introduction of aluminum and copper components in the rotor and its consequences on the alternator parameters.
Successful modifications will be implemented into practical prototypes that will constitute the basis for future models. A reduction of the hysteresis loss is realized by reducing the level of saturation in the rotor, with the saved power being converted into effective power, thus increasing the performance of the machine
