This paper presents a few aspects regarding the analysis of some dynamic regimes of asynchronous motors supplied at variable frequency. In this purpose, in the first part of the paper, there are detailed the Simulink blocks of a program for simulating the operation of driving systems with static converters with precomputed commutation moments. Then there are presented the simulations obtained with the help of this program in case when the supply frequency is modified by jump. The accent is laid on the rate of time-dependent variation of the stator current. The results obtained are compared with the experimental results obtained with the help of a high-speed data acquisition board. The paper ends with conclusions and references.
