Embodiment Construction

[0046] figure 1 A longitudinal section of a rotating electrical machine 2 is shown, which has a rotor 4 rotatable about an axis of rotation 6 and a stator 8 surrounding the rotor 4 . Between the rotor 4 and the stator 8 there is a gap 10 which is preferably embodied as an air gap. The rotating shaft 6 defines an axial direction A, a radial direction R and a circumferential direction U. The rotary electric machine 2 is embodied for example as a synchronous electric machine 12 and has permanent magnets 14 on the rotor 4 . The stator 8 comprises a stator lamination pack 16 with a winding 18 . The winding 18 has coil bars 20 which each extend in the axial direction A through recesses 22 of the stator core 16 . At least one stator winding head circuit board 24 is located on both end faces 23 of the stator lamination stack 16 . The connection of the winding 18 to the terminal box is not shown for the sake of clarity.

[0047] The stator winding head circuit board 24 has conduct...

Abstract

The invention relates to a stator (8) for an electric rotating machine (2), which stator has a laminated stator core (16) having coil bars (20) and has at least one stator winding head board (24) having an insulating main body (28). In order to reduce the axial length of the stator (8), according to the invention, conducting tracks (26) are integrated into the insulating main body (28), wherein the at least one stator winding head board (24) lies on an end face (23) of the laminated stator core (16) and wherein the conducting tracks (26) are integrally bonded to the coil bars (20).

Description

technical field [0001] The invention relates to a stator for a rotating electrical machine. [0002] Furthermore, the invention relates to a rotating electrical machine having at least one such stator. [0003] Furthermore, the invention relates to a gondola drive having at least one such rotary electric machine. [0004] Furthermore, the invention relates to a vessel having at least one such pod drive. Background technique [0005] Such stators are preferably found in rotating electric machines, especially in motors or generators for shipbuilding, and have a power consumption of at least one megawatt. [0006] Usually the stator windings of such rotating electric machines are realized as form coils, also known as bar coils. Formed coils are produced, for example, by casting or powder metallurgy. At the end of the forming coil there is a winding end which is formed by bending and hooking the conductor of the forming coil. Winding heads require a large axial construction...
