Spacer for stabilizing and insulating an end winding

摘要

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.

1. A spacer for mechanically stabilizing and electrically insulating an end winding in an electric motor, comprising:
an elastic nose having a free end; and a planar, electrically insulating sheet integrally formed at an end of the nose located opposite the free end; wherein the nose includes a projecting, elastic tab elastically bendable in a direction of the nose, the tab adapted to retain the spacer in the end winding by a spring force.
