Description

FIG.

The invention relates to electrical engineering, in particular to the fields of electrical engineering related to the design, manufacture and operation of electromagnetic actuators.

The aim of the invention is to more efficiently use the energy of the electromagnetic field and to expand operational capabilities in terms of creating fundamentally new actuators - thread yarns and thread strands and in terms of the ability to provide performance control.

Figure 1 shows the proposed device; figure 2 is a side view; in Fig. 3 is a view A-A; in Fig. 4, a - t is a thread; in Fig, 4, b - t is a thread; figure 5 is a cross section of the Converter with four working grooves (volumetric design).

The device (Figs. 1, 2, 3) consists of core 1 in the form of flexible traction conductive branches, a core 2, an excitation coil 3, eyes 4, insulators 5, crackers 6, pins 7, a guide frame 8, and movable eyes 9, spring return 10, terminal terminals 11, screw connections 12, covers 13, screw connections 14. The operation of the converter is carried out in the following modes. In engine mode, when voltage is applied to the measurment 1 and the excitation coil 3, and also when the voltage is applied to the excitation coil 3 without applying voltage to the measles 1.

In the course of the working stroke, as a result of the interaction of electromagnetic fields, the conductive branches of core 1 are deflected, as a result of which their longitudinal length is reduced, the movable eye 9 moves towards the fixed eye 4 - the engine makes a working stroke.

B. mode of the electric current generator when applying voltage to the excitation coil 3 while providing reciprocating movement, for example, by means of a crank mechanism, a movable eye 9. In this case, electric current will be generated in the flexible conductive branches moving in the magnetic field 1.

Flexible bobbin thread (Fig. 4, a) consists of a series of transducers 15 connected to the bobbin thread via swivel joints 16. As transducers 15, the devices according to Fig. 1 are used, in which the eyes 4 are made covering with respect to eyes 9 along the working docking planes m.

The flexible traction yarn can be operated in the following modes - general reduction mode when simultaneously applying to all single working voltage transducers with full working stroke,. discrete reduction mode when applying voltage to a unit or group of converters c. the goal of working out a given

stroke length, peak load compensation mode, when the subsequent converter or group of converters is turned on by a signal of a known sensor design for load. The generator mode of operation of the flexible traction thread can be ensured by installing between the transverse part of the core 2 of the transducer and the conductive branches of the core 1 spacer springs,

which, while providing reciprocating movement of the movable end of the thread, for example, by means of a crank mechanism, allows the conductive branches of the unit transducers to be moved in a magnetic field and generated an electric current. Moreover, instead of electromagnets, permanent magnets can be used.

Bending is ready (fig. 4, b) consists

from a number of flexible pull threads 17. The flexible pull strand can be operated in all of the above modes. In addition, depending on the actual load, it can work on a signal

load feedback sensor in selective optimum mode, i.e. when you turn on (shutdown) one or more flexible threads.

The return to the initial position of the transducers themselves, as well as traction threads and strands based on them, is carried out using springs or an acting load, as well as counter-running devices.

The spatial design of the transducer (Fig. 5) is a basic structure (Fig. 1) with an additional core 18 installed,

core 19 and field winding 20. The operation of the device is carried out similarly to the operation of the device in Fig. 1.

The motor characteristic can be controlled by making slits in the core 2. Thus, by forming a central axial slot in the core, a characteristic with a constant value of the pulling force of the transducer during movement can be obtained.
