Abstract

Themodeling method of steady state processesbasedonenergy is applied for analysis and optimizationof frequencycontrolledinductionelectric drive. Thismade it possible toeasilydetermine the conjunctiondegreebetween inputandoutputofelectromagnetic part of induction motor, take into accountlosses insteel andcopperat differentfrequency andvoltageand simplydefinethe optimalfrom energypoint of view motor slip on the criterion ofmaximumthermodynamic efficiency.
