05 05 4 FIG.

The invention relates to a technique for converting electrical energy into mechanical energy and can be used in electrical equipment, instrument making, telecommunications, such as telegraphy, and other fields of technology.

Tse. 1 of the invention is an increase in speed and tractive effort.

FIG. Figure 1 shows the design of an electromagnet with an attraction in the form of a fox to the core and an electrically conductive sleeve detached from the core; in fig. 2 shows the design of an electromagnet with a retracting core in the form of a sleeve.

Electromagnet has a ribbon core 1 of a magnetic conductive material twisted into a helix jointly with the excitation winding strip 2. In the hole of the core there is a rod 3 with a core 4 fixed on it and a sleeve 5 of a material with high electrical conductivity (core 1 and winding 2 with a conductor 6 of magnetic conductive material fixed inside the hollow stagnated form of the magnetic core 7. Anchor with the aid of the spring 8 is pressed by the sleeve 5 fixed on it to the end face of the core 1 and winding 2. The working gap is formed between the other end of the core 1 and core 4.

When current appears in winding 2, a magnetic note created by winding and core 1 causes the output from the core core to induce an EDS core in core 5 and the eddy current generated in the sleeve creates a counter magnetic flux. The interaction of magnetic fluxes leads to the appearance of a force that pushes bushing 5 of core 1 with winding 2. Part of the magnetic flux formed by winding 2 with core 1. passes through ring 6, magnetic cable 7, air gap, measles 4, working air gap and closes on the core 1. In this case, between the cortex 4 and the core, there arises an electromagnetic attraction force directed in the same direction as the repulsive force acting on

sleeve 5 at the opposite end of the core 1. Under the action of the total forces, the measles, overcoming the opposing force of the spring 8, move in the direction of decreasing the air gap before adhering to the end portion of the core surface 1. At the same time, the measles through the rod 3 performs the necessary work.

FIG. 2 depicts a constructive version of an electromagnet with a retracting core. Its difference from the first one is that the measles 4, when the electromagnet is triggered, can go inside the core 1 with the winding 2. This ensures a large magnitude of the working stroke and the uniformity of the tractive force of the electromagnet.

The use of two ends of a core with a winding for a COI-compliant direction of force action of magnetic fluxes on measles increases the speed and tractive effort of the proposed electromagnet with respect to an electromagnet of known design.

This technical peujeHHe increases the speed in comparison with the prototype by 30%.
