Description

The present invention relates to electric machines using cores with a collector and a ring and an iron frame, with two windings placed on the last one. One of said windings is supplied from a core through a ring and a collector and is an excitation winding, the second serves to transmit alternating current to a receiver.

In FIG. 1 depicts the electrical circuit of the proposed machine; FIG. 2 is the same as in FIG. 1, but in a slightly modified form of implementation.

The proposed electrical machine consists mainly of: / - field winding (magnetizing) (Fig. 1), // - winding feeding the receiver, M-rm (machine pipeline), R - current receiver, I - Korea with collector (rotating), K-ring connected to one collector plate. The field winding is connected between the ring / C and the brush having a current with the collection03.

torus is under pulsating voltage. Depending on the value of the self-induction of the winding /, the variable component corresponding to the pulsating voltage of the pulsating current curve will have one or another value. The pulsating current should correspond to the pulsating magnetic flux in the magnetic circuit. The variable component of the pulsing pdQ „

current gives some e-zt-vobmotkeUA

The corresponding electromotive force EZ z-if- creates in the winding // an alternating current feeding the external circuit R.

Somewhat different form of embodiment of the proposed electric machine is possible, as indicated in FIG. 2. Here, three primary windings / are placed on the rom on three separate cores, each fed from the collector and the ring by currents shifted in phase from each other by 120 °. In the secondary windings / 7 according to the above, the corresponding alternating currents, also shifted 120 ° relative to each other, must be induced.

The windings and can be connected by a triangle or a star to obtain a three-phase current in the external circuit. The magnitude of the required voltage in the external circuit can be achieved by appropriate selection of the number of turns in the secondary windings //.

The subject matter of the invention.
