Method for impregnating at least one wire winding of a component

A method for impregnating at least one wire winding of a component, in particular a stator or a rotor for an electric motor, wherein the at least one wire winding has a winding head on at least one end side of opposing end sides of the component and has an intermediate region extending between the end sides along an extension direction of the component, the method comprising the steps:

• a) heating, preferably homogeneously heating, the component;
• b) aligning the component such that the extension direction is substantially vertical and the winding head is arranged on the vertically upper end side;
• c) applying a liquid and/or solidifiable impregnating material which melts with the application of heat, to at least one first component region of the component on the vertically upper end side to introduce the impregnating material into at least one region of the winding head in such a way that the impregnating material flows due to gravity and/or capillary action from the winding head via the intermediate region in the direction of the vertically lower end side;
• and
• d) solidifying the impregnating material, wherein step c) comprises:
• c5) detecting an application quantity of the impregnating material which is applied to the first component region and/or detecting a dripping quantity of the impregnating material which drips off the vertically lower end side of the component;
• c6) determining a degree of impregnation of the at least one wire winding by comparing the application quantity and dripping quantity;
• and
• c7) regulating and/or metering an application quantity of the impregnating material based on a degree of impregnation.
