Abstract

In a method for encapsulating a winding overhang of a stator which includes a laminated core with windings inserted in grooves of the laminated core such that winding ends protrude from the grooves to form a winding overhang at a distance from a laminated core end and run in a region between the laminated core end and the winding overhang so as to form intermediate spaces between the winding ends, at least one of the intermediate spaces is spanned by a polymer layer such as to prevent a flow of encapsulating compound through the at least one spanned intermediate space, and the winding overhang is encapsulated with the encapsulating compound after placing the stator in a housing of an electric machine.
