The AC converter fed electric motors of DBM series developed at Electroprivod are described. The motors are intended to operate in electric drives with enhanced dynamic characteristics and positioning accuracy.

This paper considers variants for improving the energy efficiency of oil producing sucker rod pumps with new alternative electric drives based on valve electric motors instead of existing ones based on serial asynchronous motors. As an option, the drive of a sucker rod pump with a linear cylindrical motor valve motor is proposed.
