equivalent circuit, curves of electric motors, characteristic curves of electric motorsAbstract
This study deals with the plotting of characteristic curves, as a function of speed, of three-phase asynchronous motors with power ratings below 450 kW.
Conventional equivalent circuit, test or manufacturer's data are used and the information is processed with Python programming language; variable impedances are calculated, simplifying assumptions, standard recommendations and loss estimates are applied.
The returns of the program and some of the curves obtained are presented, between start-up times and no-load operation. The returns under different standardised load states and the values of electrical and magnetic requirements are added.
The aim is to provide an alternative method for the study of three-phase induction motors, applying the traditional principles of theoretical analysis, real construction data, practical test results and a modern programming language.
