A linear type electric drive is an electromagnetic device that creates translational (reciprocating) motion. An efficiently designed integral part of the production mechanism. Significant amount domestic oil carried out with help pumping machines. Modern energy-saving requirements make tasks improving energy characteristics and efficiency oil-producing equipment urgent.
