Abstract
Disclosed is an apparatus According to the present invention, a new winding arrangement was developed to enhance the manufacturability of stators with large length to diameter ratio and small aperture diameters such as the ones designed and manufactured for downhole pumping applications. The rectangular conductors are pre-formed to a specific shape, nested together, and inserted into the stator slots. Once the conductors are inserted, additional bending and joining operations are required to complete the coils and phases. These operations can be either fully automatic or semi-automatic. The structure of the winding allows insertion of phase and phase to phase insulation after the joining operation is completed thus reducing the risk of damage to the insulation system during the joining process. The pre-formed winding due to its ability to nest by design results is very short end-turns compared to conventional winding.
