Abstract
A spacer for mechanically stabilizing and electrically insulating an end winding in an electric motor includes an elastic nose having a free end. A planar, electrically insulating sheet is integrally formed at an end of the nose located opposite the free end. Such spacers are used in an electric motor having an iron core, whose teeth are surrounded by coils whose end windings laterally project from the iron core. The spacers are press-fitted inside openings formed by the end windings and the teeth, so that the end windings are covered by the sheet of the press-fitted spacer in the direction of an air gap of the electric motor in each case.
