 Abstract
The aim of this paper is to illustrated the evolution: M(t), M(ω), ψshd(t), ψshq(t), ψshd(ψshq), when the feeding voltage, of the asynchronous motor, is varying with 10%. The simulations are made using the programming in Matlab. This situation (when the feeding voltage is varying) is very common in auxiliary's posts of the electromotive.

 Rezumat
Scopul acestei lucrǎri este de a ilustra variaţia: M(t), M(ω), ψshd(t), ψshq(t), ψshd(ψshq), când tensiunea de alimentare a motorului asincron variazǎ cu 10%. Simulǎrile sunt fǎcute în Matlab. Aceastǎ situaţie(când tensiunea de alimentare variazǎ) este des întâlnitǎ la serviciile auxiliare ale locomotivei electrice.
