Abstract
An electrical commutator machine which serves to actuate units is proposed. The commutator machine comprises a ring-like carrying plate, which surrounds the axis of rotation of the commutator, for tubular guide casings which are made of metal, have a square cross section, are permanently connected to said carrying plate and in which brushes belonging to the commutation device are guided along the longitudinal axis of the tube and are placed under load on a contact face of the commutator. A particularly simple and advantageous structure of the commutator machine is produced if, in order to secure the casing on the carrying plate, at least two tongues which are upright with respect to the wall plane are arranged on one of the casing walls, to which tongues there are assigned insertion slits which are located in the one end of the carrying plate and detain the tongues.
