Verfahren zur Herstellung eines Preßstoff-Plankommutators

摘要

In the case of a method for manufacturing a moulded flat commutator having parts of the segments located in a cylindrical surface and in the case of which a pot-shaped blank having an outer ring flange and having a number of axially running grooves (which are open radially inwards and are arranged distributed uniformly over the circumference) corresponding to the number of segments is formed in the cylindrical part of the blank from material in the form of a board, on the outside of the cylindrical jacket of the blank, a coating having a thickness which corresponds at least to the radial thickness of the material elements which close the grooves radially on the outside is displaced from the outside of the flat part, corresponding to the surface on which the brushes will subsequently run, towards the free end of the jacket, forming the ring flange and opening the grooves.
