STATOR FOR LINEAR SUBMERSIBLE ELECTRIC MOTOR AND ASSEMBLY METHOD THEREOF Russian patent published in 2016 - IPC H02K41/02 H02K1/18 H02K15/02 

FIELD: electronic equipment.

SUBSTANCE: invention relates to linear motors for submersible units with plunger pump used for oil production. Stator consists of a cylindrical housing, inside which there are magnetic cups with inserted in them armature windings and separating group cups support elements, inner diameter smaller than that of magnetically conductive cups. On inner surface of support elements there are grooves, whose depth is greater than half difference between inner diameters of magnetically conductive cups and support elements. Magnetic cup and support elements are fitted in housing with radial clearance and fixed in it by means of fasteners.

EFFECT: higher durability of submersible electric motor and efficiency of its operation.
