摘要： Provided are a method and a tool for manufacturing a coil assembly of an electric motor for a deep well vertical turbine pump with a stator assembly that has a stator bore to receive a rotor and slots radially open to the inside which are respectively separated from each other by a stator tooth and in which electrical conductors of coils of the coil assembly lie, forming distributed windings and, at one axial end of the coil assembly, a winding head. The coil assembly is manufactured by shaping and encapsulating the coils within the tool so that the winding head extends only between an inner diameter and an outer diameter that is smaller than the diameter of the stator bore in order to enable axial insertion of the coil assembly into the stator assembly leading with the winding head in which the coils are respectively wound individually, drawn into the tool as wire bundles and encapsulated within it.

摘要： An electric motor as well as a manufacturing method for the electric motor and a manufacturing tool are provided, the electric motor being for a deep well vertical turbine pump and having a stator assembly that has a stator bore to hold a rotor and slots that are radially open to the inside, respectively separated from each other by a stator tooth, and in which electrical conductors made of round wire of coils of a coil assembly lie, with the distributed windings on one axial end of the coil assembly forming a winding head in which the coils are encapsulated. The winding head only extends between an inner diameter and an outer diameter which is smaller than the diameter of the stator bore in which the coil assembly is inserted axially into the slots of the stator assembly.
