Embodiment Construction

[0036] figure 1 The electric motor 1 according to the invention, which is designed as a drive motor for a motor vehicle, is shown in section. The electric motor 1 has a rotor 2 , a stator 3 and a housing component 4 which surrounds the stator 3 and is designed as a cooling unit.

[0037] The stator 3 comprises a hollow cylindrical stator plate 5 consisting of a stack of laminations (or a stack of plates, ie Blechpaket), a structure consisting of a plurality of wires with a winding head 7 protruding axially from the stator plate 5 as The distributed winding 6 of the wave winding and the insulating disk 8 . Distributed windings 6 are arranged in radially inwardly extending slots of stator plate 5 .

[0038] as presented zoomed in from figure 1 Details of X's figure 2 As can be seen in , the distributed winding 6 or winding head 7 configured as a wave winding is formed from a plurality of surrounding annular coil layers 9 , 9 ′, 9 ″ arranged one above the other. In the case...

Abstract

The invention relates to a method for producing an electric motor comprising a rotor and a stator having a hollow cylindrical stator plate and a distributed winding consisting of a plurality of surrounding coil layers arranged one above the other. A placeholder for a temperature sensor for detecting the temperature of the winding is brought between the first coil layer and the adjacent second coil layer of the winding head of the winding in the axial direction, so that the placeholder is arranged on the first In the gap-like recess extending between the coil layer and the second coil layer. The first coil layer is pressed against the peripheral surface of the placeholder and against the second coil layer and is plastically deformed such that the tension existing between the outer peripheral surfaces of the two coil layers and the peripheral surface of the placeholder is reduced. free space and increase the abutment surface between the outer peripheral surface of the first coil layer and the peripheral surface of the placeholder. By removing the placeholder, a receiving space is formed in the winding head into which the temperature sensor is subsequently inserted. The invention relates to an electric motor with a temperature sensor.

Description

technical field [0001] The invention relates to a method for producing an electric motor, in particular an electric motor which can be used as a drive machine of a motor vehicle, with a winding with a winding head and arranged as a wave winding and with a detection winding or a winding A temperature sensor for the temperature of the head. Furthermore, the invention relates to such an electric motor. Background technique [0002] It is generally known that electric motors must be protected against overheating in order to avoid, inter alia, damage to the windings and / or negative damage to the magnets. This is usually brought about by the temperature of the electric motor being monitored directly or indirectly at one or more points and, starting from a predetermined temperature, measures being taken in order to counteract a further temperature increase. In most cases, this is achieved by control or regulation by means of power electronics. [0003] The winding head is usuall...
