Embodiment Construction

[0049] Figure 1 to Figure 6 A diagram showing a first embodiment variant of the invention. figure 1 and figure 2 A section view through the stator coil carrier unit 2 and a part of the stator yoke ring 1 is shown, respectively. image 3 and Figure 4 A perspective view of part of the stator coil carrier unit 2 and the stator yoke ring 1 is shown. Figure 5 shows a sectional view through the stator yoke ring 1 and Figure 6 A sectional view through the stator yoke ring with inserted stator coil carrier unit 2 and air core coil 4 is shown.

[0050] The stator coil carrier unit 2 (which can also be referred to as a stator pole) is replaceable and is inserted from the radial direction R into the slot 7 of the stator yoke ring 1 and secured against slipping out by means of the prismatic connecting element 3 . For this purpose, the stator coil carrier unit 2 has a projection 5 with a first opening 6 .

Abstract

The invention relates to a stator (10) for an electric machine (16), comprising a stator yoke ring (1) for receiving stator coils, characterised by: at least one stator coil carrier unit (2) for receiving coil windings, which is designed such that it can be plugged detachably - as a whole or with a first coil body element (2a) - on the stator yoke ring (1) in the radial direction (R). The invention also relates to an electric machine and an electric or hybrid-electric aircraft. The invention further relates to a method for producing e stator according to the invention.

Description

technical field [0001] The invention relates to a stator for an electric machine with a stator yoke for receiving stator coils. Furthermore, the invention relates to an electric machine with such a stator and to an aircraft with the electric machine. Furthermore, the invention relates to a method for producing a stator. Background technique [0002] In electrical machines, such as, for example, electric motors with a concentrated stator winding, such as asynchronous machines or permanently excited synchronous machines, the coil body that is damaged in the event of an insulation fault (for example due to a short circuit of the winding) is only due to the pole geometry. Can be replaced with high technical outlay. In the typical winding process of concentrated windings around individual poles (that is, instead of being placed into slots in the longitudinal direction as in the case of distributed windings, the conductors of the coils are wound directly around each individual s...
