Description

A non-contact electromachine amplifier, rotated by an asynchronous electric motor, is known. With a phase rotor and containing two stages of amplification, performed by Hbte in the form of combined in one Magneto (a wire of electromagnetic multi-phase generators.

The invention described here differs from the well-known fact that in it "the rotor of the generators | placed a compensation winding connected via a rectifier to the phase winding of the rotor of an induction motor, on the stator of which the additional winding is placed Generators are made in-pole. This provides a linear overall characteristic.

The drawing shows a diagram of a contactless elec trophone amplifier, which is a two-stage single core amplifier, both stages of which are made in accordance with the compatibility conditions of two electric machines in the same circuit. The stator package is made as in an asynchronous maschine. The rotor package for the output cascade of the amplifier is made in a pole of electrical steel sheet with grooves at the poles for the impedance winding. For the first cascade, the rotor 1 1 has a number of titles, equal to the number between the pole pro.meshkov.

In the grooves of the stator pack laid winding

In the interpolar space of the rotor, the winding 3 of the excitation of the output stage with the number of poles 2 /, is curved. // G-phase output winding 4 of the nerve cascade with the number of poles 2 / ,, serving to feed rectifier 5. In the slots of the rotor located at the poles, a sensational winding 6 is laid with the number of zeroes 2 ,,.

In one case with an amplifier, there is a drive induction dvigigatel. In the grooves of the stator package of a drive motor, K | rum 0 of a conventional three-phase winding 7, a winding of 8 reverse links is laid with the number of poles 2, ..

Winding 9 is laid in the slots of the rotor package

engine that simultaneously serves for

rotary drive power W. for

the settings of the offset is provided by the niyntive resistance //.

The amplifier works as follows. The engine is started by turning on winding 7 to the network. When the control winding is turned on, a constant voltage in the stator of the amplifier causes an abrasive flux and a winding 4 is induced. d. Rectifier 5, inspected on semiconductor diodes, supplies a constant N current to winding 3. The current flowing through winding 3 creates a tray with the number ffiOviiocoB rotating relative to the stator. This flow in the winding 2 aavoDIT e. d. The terminals of the winding 2 are connected to the semiconductor switch 12. If you connect the same electrodes of the valves of the commutator, you get a rectifier bridge. The voltage across the valves is distributed in such a way that there will always be a pair of valves that are located diametrically and adequate to the brush contact of the collector generator. Pr: and On-load, DC current will flow and create an “magnetising force (and. P.) Of the REACTIVE core. , H. with. the reaction of the core is compensated, with (Using the winding 6. Proportional to the change of the load current will change. "p. winding 8, the output voltage is V1 | Mitel 10 and the current in the winding 6. In the amplifier, the response of the core along the transverse axis is weakened the interpolar space and can be fully collimated using winding 6 using current feedback. Therefore, the external characteristics in the amplifier will be rigid and linear.
