Electric submersible pumps

A downhole electric motor has a first multiple-phase section (3001) and a second multiple-phase section (3001') and separate supply leads (110, 110') for supplying the first and second sections (3001, 3001') with electrical power from the surface. The first and second sections (3001,...

description	A downhole electric motor has a first multiple-phase section (3001) and a second multiple-phase section (3001') and separate supply leads (110, 110') for supplying the first and second sections (3001, 3001') with electrical power from the surface. The first and second sections (3001, 3001') may comprise two sets of phase windings wound on a common stator such that the motor may be driven by supply of power to only one of the sections (3001, 3001') in the event of failure of power to the other section. Alternatively the first section may comprise a first set of phase windings wound on a first motor stator and the second section may comprise a second set of phase windings wound on a second motor stator, the first and second sections having a common rotor or mechanically coupled rotors. Such a motor construction is advantageous in that it makes it possible to extend the reliability of the entire pumping system by means of cooperative duplication of failure prone electrical elements.
