Abstract

In order to reduce the time required for producing slot insulations, the invention provides a method for producing slot insulations (138) for winding slots (14) of a component (16) of an electrical machine, comprising a) providing a strip (10) of insulating material, c) cutting an insulating strip piece (12) from the strip (10), d) shaping the insulating strip piece (10) to match the shape (54-57)of the winding slot (14) and e) inserting the shaped insulating strip piece (12) into the winding slot (14), wherein at least steps d) and e) are carried out in parallel for at least two insulating strip pieces (12) which are to be inserted into different winding slots (14). The invention further describes an apparatus (20) for carrying out the method.

Description

technical field [0001] The invention relates to a method for producing a slot insulation for a winding slot of a component of an electric machine. The invention also relates to a device for producing a slot insulation for a winding slot of a component of an electric machine. Background technique [0002] Refer to the following documents about the technical background of the present invention: [0003] [1] US 2 282 773 B1. [0004] The invention is based on the field of manufacturing electric motors or other electric machines, such as generators, which are designed for high power, reliable operation and high efficiency. In particular, electric motors are to be produced which can be used as traction motors for electric or hybrid vehicles and which, for example, have a rated power of between 20 kW and 400 kW. In order to construct the stator of such a high-performance electric machine, it is advantageous to provide as high a coil density as possible. For this purpose, it is...
