Analysis of losses in the cable line of well submersible electric motor
2017 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2017More than half of the oil wells fund in the Russian Federation is operated with the help of electric submersible pumps providing up to 75% of all oil produced in the country. However, electric submersible pumps have a rather high specific energy consumption in the extraction borehole fluid.

Mechanical characteristic of submersible asynchronous electric motor
Russian Electrical Engineering, 2010More accurate torque-sleep formulas have been developed based on the equivalent circuit of a multicontour induction motor (IM). Methods of taking into account the saturation and skin effects on machine parameters are discussed. High-order and space harmonics and their dependences on the rotor speed are also included in the analysis.
