Disposed at at least one end of the plate stack is an insulating plate. Furthermore, insulating strips are provided on the plate stack, between adjacent windings, which are supported on radially protruding shoulders on the insulating plate.

Electric machine with a stator and a rotor

The invention relates to a commutator with contact segments, arranged at a distance from each other and forming a brush running surface. Each contact segment is soldered to a securing portion of a metal segment support piece. The commutator has a hub body made from an electrically insulating material which supports the segment support pieces which are each provided with a winding connector hook. According to the invention, at least one solder barrier recess is provided in the upper side of the securing portion facing the contact segment and/or in the under side of the contact segment facing the securing portion.
