Problems solved by technology

[0003] The disadvantage of this prior art is that the stator winding heats up during operation of the stator or the electric motor and produces power losses through the heating
In addition, heating of the stator windings can lead to overheating of the stator, which can lead to self-destruct

Embodiment Construction

[0041] figure 1 An exemplary electric motor 100 , which is embodied as an inner rotor motor with an inner rotor 180 and an outer stator 150 , is shown. The electric motor illustrated has a stator core 153 provided at least in sections with a plastic casing 155 , on which a stator winding 157 is arranged. The outer stator 150 is hereinafter referred to simply as "stator 150" for simplicity of description.

[0042] It should be pointed out that figure 1 The electric motor 100 in is only schematically shown, this is because the structure and functionality of suitable electric motors are sufficiently known from the prior art, so that the electric motor 100 is omitted here for the purpose of brevity and simplification of the description. In-depth description. Furthermore, it should be pointed out that the electric motor 100 is shown as an inner rotor motor only by way of example and not in order to limit the invention, since the invention can also be used in an outer rotor motor...

Abstract

In a stator (150) for an electric motor comprising a stator core (153) which has at least one stator tooth (214) which is provided with a first winding section (257) of an associated stator winding (157), wherein insulating paper (230) is arranged at least in sections in the region between the first winding section (257) and the first stator tooth (214) to electrically insulate the stator core (153) from the stator winding (157), a thermally conducting intermediate layer is arranged at least in sections in the region between the insulating paper (230) and a winding layer of the first winding segment (257) facing the insulating paper (230) for a planar heat-conducting connection of the first winding section (257) to the first stator tooth (214).

Description

technical field [0001] The invention relates to a stator for an electric motor having a stator core with at least one first stator tooth provided with a first winding section of an associated stator winding, In this case, insulating paper is arranged at least in regions in the region between the first winding section and the first stator tooth for electrical insulation of the stator core from the stator winding. Background technique [0002] Stators of this type are known from the prior art with stator cores which are provided for use in electric motors. The stator core has stator teeth which are provided with associated winding sections of the stator winding. For electrical insulation of the stator core from the stator winding, insulating paper is arranged in the stator core between the winding section and the stator teeth. [0003] A disadvantage of this prior art is that the stator winding heats up during operation of the stator or the electric motor and produces power ...
