Problems solved by technology

[0004] Known solutions for detecting the rotor position of the rotor of a rotary electric machine have the disadvantage that measuring the exact adhesion of the film requires high precision and slows down the manufacturing process of the stator
Therefore, the manufacturing cost is relatively high
For this reason, solutions of this type are especially unsuitable or only limitedly suitable for mass production

Abstract

The invention relates to a method for producing a stator (1) for an electrical machine (2), the method having the following steps: - providing a stator with a plurality of teeth (4) and a plurality of adjacent stator teeth (4) The stator base body (3) of the stator slot (5) formed in between, - the first conductor line (6) is produced on the air gap side (7) of at least one stator tooth (4) by means of a cold plasma method, - applying an electrically insulating first insulating layer (8) to the first main section (9) of the first conductor track (6), wherein the first insulating layer (8) is not applied to the first conductor track (6) on the first subsection (10) and - by means of a cold plasma method a second conductor track (11) is produced on the first insulating layer (8) and on the first conductor track (6) on the subsection (10). Furthermore, the invention relates to a stator (1) for an electric machine (2) and an electric machine (2) with the stator (1).

Description

technical field [0001] The invention relates to a method for producing a stator for an electric machine. Furthermore, the invention relates to a stator for an electric machine and an electric machine. Background technique [0002] There are different types of motors. In particular, a distinction is made between rotary and translational motors. A rotary electric machine has a mostly fixed stator and a rotor that is rotatable relative to the stator about an axis of rotation. Translating motors, such as linear motors, have a mover that can move in translation relative to a mostly stationary stator rail. The relative movement of the rotor relative to the stator or of the mover relative to the stator track is achieved by generating an alternating magnetic field which interacts with the static and / or dynamic magnetic field. In particular, the invention relates to rotary electric machines. [0003] Accurate detection of the rotor position of the rotor of a rotary electric mach...
