Abstract

A device for increasing the magnetic axial force of the displacement type armature motor in motors is provided. The device comprises an iron ring (10) furnished with an outer chamfer (11) matching with the conical course of the rotor (6). The spring-loaded pretensioning of the iron ring (10) suffices for the attachment of the brake support casing (7) on the support ribs (8). The iron ring can be permanently and reliably attached to the rotor motor at low expenditure.
