Abstract: The article is devoted to the application of controlled electric drives enabling a smooth start of a pumping unit, control of performance subsurface pumping units as the subsurface pump wears out, control the speed the drive engine rotations during the cycle of the plant to reduce the effort in the sucker rods and other structural assemblies of the unit. The use of controlled electric drives has increased the turnaround time of the subsurface pumping unit, increase its productivity, efficiency, cosφ of the electric drive, and thereby reduce the cost of crude oil.
