Rezumat
Lucrarea de fata urmareste o analiza comparativa dpdv a performantelor obtinute de la un motor asincron
trifazat cu rotorul in scurtcircuit si unul cu infasurare bobinata pe rotor. Studiul efectuat porneste de la un motor a carui
rotor in colivie este inlocuita cu o infasurare bobinata in urma reproiectarii infasurarii rotorice. O atentie deosebita se
acorda proiectarii infasurarii rotorice pentru a obtine cupluri ridicate la pornire. Caracteristicile pentru cele doua structuri
sunt prezentate comparativ si sunt obtinute prin analiza de camp utilizand software special de calcul.

Abstract
The presented paper aims a comparative analysis, from the performance point of view, between a squirrel
cage tri-phased induction motor and a wound rotor construction. The study uses as starting point an induction motor with
squirrel cage rotor, wich has been replaced with a winding after a design algorithm. Particular attention is given to the
design of the rotor winding in order to obtain high starting torque. The characteristics for the two motor types are presented
in a comparative manner. This characterics are obtained using field analysis in a special computing software
