FIELD: oil and gas industry.
SUBSTANCE: invention relates to petroleum industry and can be used for driving submersible oil-producing pumps, as well as for driving any other device with rotating rotor. Sectional motor comprises cable entry, hydroprotection and several sections including housing, stator with windings connected to star, and rotor. Windings are connected to star outside sections, and sections are made with same connectors. Winding connection to star can be made in separate module, in hydro-protection or in telemetry system block (if any).
EFFECT: invention is aimed at improving manufacturability of production and installation in borehole sectional motor due to unification of its constituent sections design.
