The PMSM-drive submersible centrifugal pumps efficiency determining

Abstract

In the paper, the problems of modelling and calculating the electromagnetic moment are considered. The study subjects are submersible induction and synchronous electric motors for centrifugal pumps. This task is relevant, because the requirements for oil production technology are growing. A brief description of the electric submersible pumps (ESPs) is given and the main design features of submersible motors are presented. The software for constructing and calculating the mathematical model of a submersible motor is selected. The field lines pictures in the section of motors are created. Characteristics of moment-current, moment-slip, moment-angle are built. Comparison results of two types of submersible motors are presented.
