Abstract: In a method for manufacturing an electric motor comprising a rotor and a stator a placeholder for a temperature sensor is inserted in the axial direction between a first coil layer and an adjacent second coil layer of a winding head such that the placeholder is situated in a gap-shaped recess extending between the first and the second coil layers, the first coil layer is then pressed onto a circumferential surface of the placeholder and onto the second coil layer and is plastically deformed such that a space between the lateral surfaces of the two coil layers and the circumferential surface of the placeholder is reduced, and a contact surface between the lateral surface of the first coil layer and the circumferential surface of the placeholder is enlarged. By removing the placeholder, a receiving chamber is subsequently formed in the winding head, into which a temperature sensor is then inserted.

Abstract: The invention relates to a method for producing an electric motor (1) comprising a rotor and a stator (3), the stator (3) thereof comprising a hollow cylindrical stator metal sheet (5) and a distributed winding (6) consisting of a plurality of peripheral coil layers (9, 9?, 9?) arranged one above the other in a layered manner. According to said method, a place holder for a temperature sensor (11) for detecting a temperature of the winding (6) is inserted in the axial direction between a first coil layer (91) and an adjacent second coil layer (9?) of a winding head (7) of the winding (6) in such a way that the place holder is arranged in a gap-like recess extending between the first coil layer (9*) and the second coil layer (9?).

Abstract: An electric motor, particularly an engine of a motor vehicle, has a temperature sensor for monitoring the operating temperatures of a winding. The temperature sensor is inserted through a radial through-hole at the periphery of the insulation element into a recess which is delimited between a shaped-out portion on the corresponding projection of the insulation element and the winding. The shaped-out portion has a slope so that a translational displacement of the temperature sensor at the same time leads to an increase in the biasing force of the temperature sensor with respect to the winding. It is thus possible to ensure the desired pre-tension force, and therefore a reliable contact surface between the temperature sensor and the winding, as a result of the connecting force and, at the same time, secure the temperature sensor with force fit in the shaped-out portion.
