Abstract
The analysis of the operating modes of the frequency-controlled electric drive of the pumpjack with the use of dynamometer cards, wattmeter diagrams and the mathematical model of the pump-jack, the effect of the shape of the dynamometer card on the operating mode of the electric motor of the pumpjack is determined. The ways of protection of the transistors in the frequency converter from voltage increase are considered at the transition of the electric motor to the regeneration.
