SUBMERSIBLE SYNCHRONOUS ELECTRIC MOTOR Russian patent published in 2013 - IPC H02K19/10 H02K19/36 H02K1/06 

Abstract RU 2498484 C2

FIELD: electricity.

SUBSTANCE: submersible synchronous electric motor contains stator with imbricated core installed in stator casing, the core has radial teeth on inner surface; inside stator there is rotor consisting of m stacked packs divided by central bearings; at outer surface of rotor there are also teeth; between rotor and stator there is a minimum positive allowance and at stator poles there are identical wound inductance coils connected into phases. Each phase consists of two parallel paths, and each path includes in-series diode and coils; diodes in parallel paths are connected in opposition. According to the invention at that each pole of stator has two grooves in which there is a slot wedge made of dielectric material; diodes are collected to rectifier block installed in stator; number of rotor central bearings is m+1, and rotor is fixed in stator due preloaded installation of the bearings.

EFFECT: improving operational reliability and increasing service life of the electric motor, optimising workability of its manufacturing process.
