FIG. Figure 1 shows a unipolar transducer, longitudinal section; in fig. 2 is a section A-A in FIG. 1, in FIG. 3 - schematic scan of the windings of the converter core.

The unipolar converter contains an inductor, including a double middle pole 1, roma 2 and 3, lateral poles 4 and 5, excitation coils 6 and 7 and a rotor made of II identical insulated ferromagnetic elements 8 assembled into a cylinder with bandings 9. The rotor is located on the shaft 10, mounted in bearings 11 and 12. In each of the n elements 8, insulated rods 13 of the alternator core winding are placed, connected by their ends to the contact rings 14 of the generator. On the surface of the elements 8 evenly around the circumference of the rotor mounted brushes 15 engine. To increase the resulting motor EMF, the number of brush pairs 15 of the engine on the surface of the rotor elements 8 is one and a half times smaller than the number of elements B of the robora. In order to exclude parallel connection of all rotor elements 8 during commutation, as well as motor EMF pulsations, the distance between the side faces of the adjacent engine brushes 15 is not less than the width of the rotor element 8. The rotor elements 8, interconnected in series, as active conductors, by means of the brushes 15 of the motor and the current leads 16 form the core winding of the motor.

The cores 13 of the core winding of the generator, interconnected in series or in parallel-parallel through the contact rings 14 of the generator, the corresponding brushes 17 and conductors 18, form the core winding of the generator.

The unipolar converter works as follows.

In the presence of a current in the coils 6 and 7 of the excitation, a longitudinal magnetic flux of the machine occurs (Fig. 1), which

radially enters the double middle pole 1 and, being divided into two parts, it closes through the lateral poles 5 and 4 (the path of magnetic flux cooling is shown by a broken line).

Terminals are applied to terminals 19 and 20 from an external power source, and a current flows through the rotor elements 8.

The interaction of this current with the magnetic flux creates an electromagnetic moment that causes the rotor to rotate.

In the rods x13, the core winding of the generator is induced by EMF. The load is connected to the terminals 21 and 22 of the generator.

The design of the converter provides a higher use of the active part of the rotor, which leads to an improvement in mass and size parameters, which is more noticeable with the growth of 25 the number of consecutive electrically connected active sections of the core of the converter.
