Embodiment Construction

[0111] exist figure 1 A view of the stator 1 is shown in section along a plane containing the central axis 9 of the stator 1 . In the refinement shown, the stator 1 is designed as a disk-like object provided with cutouts 2 . The stator 1 has a region configured as a stator pole carrier 3 which, in the exemplary embodiment shown, also includes the outer circumference of the side surfaces of the stator 1 . In the design shown, the outer periphery of the side surface of the stator 1 roughly describes a circle, so that the central axis 9 of the stator 1 intersects the center of the circle and coincides with the axis of rotation of the rotor 16 of the electric machine. Proceeding from the inner surface of the stator pole carrier 3 , together with the further stator poles 8 ′, 8 ″ there is arranged on the stator pole carrier 3 with a first side edge 5 and a second side edge which is not visible in the shown figure. 6 of the first stator pole 4 and the second stator pole 7.

Abstract

The invention relates to a stator for an electrical machine having at least one rotor. The stator is formed as a body provided with at least one opening and having at least one ferromagnetic material. The stator also has at least one region designed as a stator pole carrier, which surrounds a central axis of the stator at least partially, at least one first stator pole with at least a first edge and a second edge, and at least one second stator pole. The stator poles are preferably aligned substantially facing along a radial direction, arranged directly or indirectly on the stator pole carrier. The invention also concerns an electrical machine having at least one stator pair having a first stator and a second stator. Moreover, the invention concerns a method for assembling an electrical machine.

Description

technical field [0001] The invention relates to a stator for an assembleable electrical machine with at least one rotor, wherein the stator is designed as a disk provided with at least one recess. Furthermore, the invention relates to an electric machine and a method for assembling a tubular electric machine. Background technique [0002] It is known to construct electrical machines from a rotor, a stator surrounding the rotor and a winding (mostly consisting of copper wire provided with insulating material) surrounding the rotor. Examples of such electric machines are transverse flow machines. However, such electrical machines can have the disadvantage that the power density is reduced relative to the theoretical optimum due to the design. The reason for this can be, in particular, that the winding has a winding head and / or is produced due to manufacturing tolerances. Contents of the invention [0003] The invention aims at increasing the power density of such electric...
