Abstract: The invention relates to the field of electrical engineering, in particular the design of linear electric motors for submersible installations with a plunger pump, and used for oil extraction. The technical result is to increase the durability of the submersible electric motor and the efficiency of its operation. The stator consists of a cylindrical housing, within which are installed magnetically conductive cups incorporating armature coils and support elements separating the groups of cups, whereby the inner diameter of which is less than the inner diameter of the magnetically conductive cups. On the inner surface of the support elements, grooves are provided, the depth of which is more than half the difference between the inner diameters of the magnetically conductive cups and the support elements. Moreover, the magnetically conductive cups and the support elements are installed in a housing with a radial clearance and are attached therein by fastening elements.
