  • Publication number: 20240146143
    Abstract: A stator for an electric drive unit, in particular an electric motor, and to a method for the production thereof. The stator for the electric drive unit comprises a stator core having at least one stator pole; a stator winding which forms all coils from a continuous winding wire; at least one insulating cap, on which a plurality of contact receiving pockets are arranged for receiving the winding wire; a number of deflection domes which are distributed on the outer lateral surface of the cap; and wire guiding contours at the outer lateral surface of the insulting cap for spacing the winding wire; wherein the plurality of contact receiving pockets each have a receiving region for the winding wire which has a different design, and wherein the plurality of contact receiving pockets comprise at least one deflection balcony.

  • Patent number: 11682938
    Abstract: A stator of an electric motor having a stator core with a plurality of salient stator poles, an insulating cap, a stator winding consisting of a winding wire, and an interconnection unit with a plurality of winding-wire receptacles having an inside, wherein the winding wire is surrounded by a material constituting the winding-wire receptacle and connected and welded thereto on the inside. The stator is of an electric motor which is of a very high quality and precision so that high-current applications are possible. Without any major adjustments, the stator is combinable with different winding connections and is flexibly adaptable to the rest of the motor and possibly to the electronics design. The manufacturing method is capable of being flexibly adapted to different wire diameters.

  • Patent number: 11114906
    Abstract: A stator in an electric motor and to a method for producing the stator in which a plurality of individual coils are wound on laminated stator poles and are provided with an insulation, wherein the insulation bears connection contacts for bringing the individual coils into contact with a printed circuit board, wherein the connection contacts are press-fitted into the printed circuit board. The present stator provides for a compact size and for simple and economical joining processes. In a preferred embodiment, the electric motor is a dosing pump motor for drug delivery systems.
