The invention relates to electrical engineering, in particular to electrical collector machines.

The aim of the invention is to increase the efficiency of the machine and improve the switching.

FIG. 1 is a printed diagram of the proposed collector machine J in FIG. 2 - additional collector plates; in fig. 3 - part of the surface of the collector; in fig. 4 shows the section A-L in FIG. 3

The collector electric machine contains a collector containing the main conductive plates 1, separated by insulating 2 and connected — to the winding of the core 3. On each edge of the main conductive plates, an additional conductor pc1e plates 4 are installed that are of equal length with the main ones. Additional conductive plates are parallel to the main plates and insulated with 2.

The additional conductive plates are connected to the winding terminal of the core connected to the main plate through resistors 5. The number of additional conductive plates 4 and resistors 5 is chosen based on the condition of providing arc-free switching. The number of resistors can be reduced by connecting additional current-conducting plates 4 with jumper 6, which, in turn, connects to main 1 or preceding; with a conductive plate 4 through resistors 5. Additional conductive plates 4 in the cross section are made according to shape main current plates. On the main conductive plate 1, an additional cockerel 7 is installed. On the cockpits 7 of the main 1 and additional plates 4, resistors are mounted, which are located on the side opposite to the windings of the core 3. The resistance of the resistors 5 is selected based on the condition that each subsequent resistor 5 has a resistance greater than the previous one. The jumpers 6 of the additional conductors of the plates 4 are located on the side opposite to the windings of the core 3. With the main 1 and additional 4 conducting plates, one brush 8 is contacted for each power supply source. Equidistant from main to

Additional conductive plates and jumpers between them are made in one piece and form a U-shaped structure, with the equidistant additional plates arranged parallel to each other, and the jumper is perpendicular to them. The jumper to the mezzadine equidistant from the main additional conductive plates is located on the front side of the collector.

The proposed solution allows to increase the efficiency of the collector machine and its switching characteristics.
