| Abstract |
For reduction of induction motors vibrations in vari-able-frequency electric drives the combined designing of semi-conductor converters and asynchronous machines is carried out. There were developed models of an electrical systems num-ber that allow calculating harmonic composition of currents and voltages of electrical machines with the regard for peculiar-ity of semiconductor converters, control algorithm accurately enough. For evaluation of vibrations are used the equivalent circuits of motors with the regard for timing and spatial har-monic components. Combined examination of results of elec-tromechanical processes and vibrations allows adjusting induc-tion motors parameters, drives circuits, control algorithms. |
