Description

The present invention relates to a device of high frequency dynamos using a serrated stator, the winding of which consists of a series of series-connected coils and a serrated rotor, designed in such a way that the distance between the rotor slots is twice the distance between the stator slots.

The action of this machine, with an appropriate to the already known type of inductor machines, is based, as usual, on a periodic change in the magnetic flux in a circuit with a constant magnetic motive force, by changing its magnetic resistance.

A distinctive feature of the proposed machine is that the field winding is placed on the rotor, and the poles of such an inductor rotor are supplied with alternating protrusions and depressions arranged in such a way that each protrusion on one side corresponds to a depression on the other side of the inductor.

In FIG. 1 shows a schematic of the proposed machine.

FIG. 2 is a schematic of the stator winding connection.

This machine consists of a stator a (Fig. 1), equipped with teeth Zj and depressions 9, and a rotor cG, which is an ordinary electromagnet with this, however, the peculiarity that there are open slots on the pole surfaces of its N VI / S poles a, the distance between which is twice the distance between the slots 9 of the stator a.

The stator a is provided with a winding g (Fig. 1), and the coils of the latter are placed in the slots 9, being fitted onto the stator teeth 1 through one tooth. A circuit for connecting the stator winding coils in series is shown in FIG. 2. Hollows in on the rotor, located in such a way that each tooth in - one side corresponds to a depression in the other side of the rotor. When the latter rotates in the stator winding, a variable high-frequency electromotive force will be induced, and if there were no teeth and depressions on the pole surfaces of the rotor, then, with this scheme

The compounds (Fig. 2) of electromotive forces induced in separate sides Zi and Z2 of coils r would be mutually destroyed. If these teeth and valleys are present, this is eliminated by the fact that one. The moment when the rotor prong (Fig. 2) is rotated against some side Zi of the coil g, opposite the other side 2, due to the fact that the step along the rotor valleys is twice as large as the same stator, the depression appears. In the r side of each coil r, it is induced by a stream emanating from the prong in, some electromotive force, while in the side 32, due to the large magnetic resistance to flow through the hollow in, the electromotive force either does not arise at all, or there is much less magnitude than the electromotive force induced in the z side, so that at the moment in the stator only one direction electromotive force will take place. When rotated half a step along the rotor grooves, the direction of the electromotive force in the stator winding changes due to the fact that now the electromotive forces are induced in the sides of the z-core of r, and not in the sides of Zj.

The subject of the patent.

A high-frequency dynamo using a toothed stator, the winding of which consists of a series of coils connected in series, and a toothed rotor, designed so that the distance between the rotor slots is twice the distance between the stator slots, characterized using a rotor in the form of a carrying winding excitation and rotating inductor 6, the poles N and S of which are equipped with alternating protrusions and valleys arranged in such a way that each protrusion on one side corresponds to a depression on the other side no inductor.
