Abstract: Systems and methods for constructing electric motors in which a stator core includes inner and outer portions that enable slots for magnet windings to be open during construction and closed in the completed motor. One embodiment comprises a method in which an inner stator core having a plurality of slots is formed by stacking a set of laminations. The slots are open radially outward from an axis of the inner stator core and which are configured to accommodate turns of magnet wire. After the magnet wire is positioned in the open slots, an outer stator core comprising stacked laminations is positioned around the inner stator core, enclosing the slots. The inner and outer stator cores are then positioned within a housing and assembled into a downhole motor.

Abstract: Electro coiled tubing (ECT) can be utilized to provide electrical power to equipment in wells. A long length of ECT is provided with protrusions welded on the inside of the tubing at selected intervals to form support shoulders. Anchors with a load shoulder are attached to the electrical cable enclosed in the tubing such that the load shoulder contacts the support shoulder created by the welded protrusion. The weight of the electrical cable can then be transferred to the tubing via the contact between the load shoulder and the support shoulder. The protrusions are welded to the tubing and the anchors are attached to the cable during the manufacturing process.
