Embodiment Construction

[0034] figure 1 A schematic longitudinal section through an exemplary embodiment of an armature 1 is shown. The armature 1 is designed for use in a linear actuator. The armature is configured as a rotational profile about the axis of rotation A, wherein, by figure 1 The geometry of the armature 1 is obtained by rotation of the U-shaped surface profile in the longitudinal section, where the surface profile is in figure 1 The upper part of , that is, above the axis of rotation A, is highlighted with a thick line L.

[0035] The armature 1 has a first armature sleeve 3 with a central molding 5 . A plurality of filler plates are arranged on the central profile 5 , of which here only one filler plate is identified with reference numeral 7 for the sake of clarity. Furthermore, an annular plate arrangement 9 is arranged on the central profile 5 , by means of which, viewed in the axial direction, the filler plate 7 is secured.

[0036] The armature 1 also has a second armature sl...

Abstract

The invention relates to an armature (1) for an electric motor, wherein the armature (1) has a U-shaped profile of rotation in longitudinal section, wherein the armature (1) has at least one first armature sleeve (3), the first armature sleeve (3) has a central profile (5) on which a plurality of filler plates (7) are arranged, the filler plates are also arranged on the The annular plate assembly (9) on said central profile (5) is held axially.

Description

technical field [0001] The invention relates to an armature for an electric motor and a method for producing an armature for an electric motor, wherein the armature has a U-shaped profile of rotation in longitudinal section, wherein the armature has at least one first An armature sleeve, the first armature sleeve has a central molding. Background technique [0002] Armatures for electric motors and methods for their manufacture are well known. Electric motors are used, for example, in ABS and / or ESP brake control systems to drive hydraulic pump elements that run mostly linearly. The hydraulic pump element discharges or transports the working medium, ie the brake fluid, from the wheel brakes of the system to the wheel brakes of the system via valves. Such electric motors can be designed as linear motors or linear actuators. The linear movement for the pump function can then be generated directly. In principle, it is known to manufacture armatures for such electric motors ...
