MULTI-SECTION VALVE MOTOR Russian patent published in 2019 - IPC H02K29/00 H02K21/14 H02K16/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and machine building, in particular, to multisection valve electric motors of submersible pumping oil production units. Valve electric motor consists of at least two modules, each of which consists of rotor with permanent magnets magnetized in radial direction, stator with phase windings, similar windings of which are connected in series. Each joint of modules has two-threaded flange with lock nut, spline coupling, rotary terminal block, fixed terminal block and insulating sleeves. On bodies of stators and on ends of spline ends of shafts of rotors, which are connected with splined coupling, there are elements of circular orientation, which provide mutual angular position of similar rotor poles with like phase windings of stator of each module.

EFFECT: technical result is creation of multisection electric motor design with possibility of its parameters fine adjustment during assembly.
