Asynchronous submersible electric motors are currently used most commonly to drive electrical submersible pumps. At the same time, the possibility of improving their performance has been practically exhausted, and the need to reduce power consumption presents specialists with the task of increasing the efficiency of energyintensive technological processes including ESP oil production. Permanent magnet motors, which have already occupied a leading position in a number of areas, have better performance characteristics than asynchronous submersible electric motors.

ESP system drives based on permanent magnet motors were not used in the oil industry until recently, but they are currently achieving wider application at the fields of various oil-producing companies.

Many oil industry equipment producers have developments in this field, e.g. JSC RITEK, CJSC KB Neftemash, and others. This also includes LLC Borets, which supplies series VEDBT 117 mm submersible permanent magnet motors for TNK-Nizhnevartovsk and SNGDU-2.
