SYSTEMS AND METHODS FOR FIXATING THE MAGNETIC COILS IN THE BLOCKED LINEAR ENGINES Russian patent published in 2018 - IPC E21B4/04 E21B4/12 H02K41/02 H02K15/12 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions refers to the field of oil production from wells. Method for fixing coils of a winding wire to a support core in a linear motor, comprising a support core assurance, wherein the support core is a hollow member configured to receive the movable portion of the linear motor in the interior of the support core, and positioning one or more coils of the winding wire outside the support core. Outer layer of the shrink material is disposed around the support core and said one or more coils of the winding wire, heat, providing shrinkage of the outer layer of the shrink material and tight fit to the specified one or more coils of the winding wire on the support core, and pressure to said one or more coils of the winding wire that reliably holds the said one or more coil winding coils in abutment with the support core.

EFFECT: simplifies the implementation, reuse and repair of the stator.
