Abstract (en)

[origin: WO2022175264A1] The invention relates to a slot insulation system for electrical rotating machines such as motors and/or generators. The invention also relates to two methods for producing such a slot insulation system. The invention disclosed for the first time here provides a technique for producing an insulation system, with which technique a reactive, non-crosslinked A-state thermoset is placed into the slot and/or onto the coil in the form of a solid film. In this way, fixing of the finally insulated coil in the slot is improved, simplified, made more cost-effective and able to be automated.
