    An electro-magnetic actuator includes a pair of magnetizable members, the one member being hollow and surrounding the other member. The other member defines a plurality of axially spaced circumferentially extending first ribs which are of reducing diameter towards one end of the member. The one member is generally of tapering construction and defines second ribs complementary to the first ribs. Recesses are defined between adjacent pairs of first ribs and accommodate windings. When electric current is applied to the windings the members move axially relative to each other to reduce the reluctance of the magnetic paths defined by the two members.

    I The invention relates to electrical engineering.
    Electromagnetic devices are known that contain & a pair of movable joints with respect to another magnetizable element and a winding through which an electric current is passed to induce a magnetic field causing the mutual movement of these elements 1.
    The closest to the proposed technical svoystvennosti is an electromagnetic solenoid device containing a magnetic system consisting of two elements of a magnetizing material - a core and a hollow located around the core; on the outer surface of the core there are protrusions between which there are depressions formed by the protrusions by. at least in some cavities there are windings interconnected so that the direction of current in one of the windings is opposite to the direction of current in another, located in the middle depression, on the inside of the core there are also protrusions parallel to the core protrusion 1 and located protrusions of the core 2.
    The disadvantage of this device is the difficulty of making protrusions on the core and on the core, which complicates the design of the ycTpq cT-va as a whole.
    The purpose of the invention is to simplify the design.
    In order to achieve the goal, the protrusions of the core and core are made annular, with the diameter of each protrusion being shifted from one end of the core to the other.
    In addition, measles may have a tapering shape.
    Moreover, internally and externally. HNORTI: COR MAY HAVE IMVE STUPVCHuyuyu cylindrical shape.
    The inner surface of the core, has a stepped shape.
    IQpoMe addition, the device can be equipped with SHELL, 4. located around the core and being an emphasis For box.
    On the inner surface of the casing QbiTb can be made longitudinal projections.
    The cavities can be made of such a size that the cross-sectional area of the windings located in the cavities is the same throughout the core.
    In a solenoid-type solenoid device, the lateral surface area of all projections can be the same.
    On fng. I tfetavleni electrofusion device, on the side, cut; in fig. 2 and 3 are modifications of the proposed device; in FIG. 2 n 3; in fig. 5 - alectromagnetic device with a casing, side view, section.
    The electromagnetic device is equipped with a core 1 and a hollow measles 2, insulated from the magnetized material (Fig. 1). Anchor 2 surrounds the If core at one end. I opoTO has. Lug 3 with thread. When pivoting the thread, the core is associated with a part that is required to be pempered when it is received by an electromagnetic drive solenoid device. On the outer surface of the core 1 is made; a set of projections 4 and depressions The diameter of the projections and depressions decreases towards the constricting end of the core. In each cavity 5, the winding is placed b / oeiflOTKK interconnected in series and made of one piece of wire. The end of the winding passes through the hole 7,: that is in the core. The windings are connected between the assemblies so that the direction of the current in the adjacent windings is opposite. When current flows, the protrusions 4 are magnetized and because the direction of the current in the neighboring windings is opposite, the adjacent protrusions are magnetized with opposite polarity. Anchor 2 tapers to one of the ends and on its inner surface protrusions 8 are made, which are divided into protrusions 4 into projections 4 located near. When current passes through the windings, the core of the other hand and the air gaps between 4 and 8 reduced. As a result of the narrowing of the design of the core BQ3 duodenal Eazors between the core and the cortex, the device can therefore develop considerable force. The internal surface and the external surface of the crp 2 have a stepped cylindrical shape. FIG. 2 bore 2 is made in the shape of a hollow truncated cone, on the inner surface of which protrusions 8 are made. This structure is lighter. compared with the design in FIG. 1, and the electromagnetic device has a large e% action. Anchor 2 (Fig. 3) has a stepwise narrowed form, however, the protrusions on the cortex as such are here OTcyTCTBsroi and limited between parts of different diameters of step 9 will determine the surface that is not in mediocre proximity to the protrusions 4 from the bottom 1. In FIG. Figures 1-3 show that a section of you, stupas 4 and 8 is narrowed to one of the ends. This is done for:) The scattering of the magnetic flux by the nearby protrusions 4 and 8, otherwise BosT can force the force in the direction opposite to the required force. / The diameter of the protrusions 4 and 8 May be increased, or decreased, In this case, the protrusions are located a pair (one relative to the other in the directions, {the longitudinal axis of the device. Fig. 5) shows a solenoid type electromagnetic device, in which the core 1 is integral with the portion of the housing 10 that is part of the mechanism associated with the electromagnet The core is also made of a magnetizing material, has the shape of a truncated cone. On its outer surface there are many circumferential depressions 5 and protrusions 4, and the farther away any projection is from the body portion 10, the smaller its diameter. anyway, it is located from the section of the housing 10. The smaller its depth, and the width of the depression increases with increasing distance from the section of the housing 10. The outer surfaces of the projections 4 are inclined to the axis of the core 1, and inside each Adina 5 houses winding 6. The windings are connected in series, so that when current passes through the windings, the direction of the current in adjacent windings is opposite. The start of the winding is connected to the core, and the other end is connected to k Lemma 11, installed. on the electrically insulating block 12, located on the section of the housing 10. A hollow measles 2, also made of a magnetized material, is located around the core. This measles can be considered as a set of cylindrical rings, decreasing in diameter, interconnected on inclined sections 13. The inner faces of the inclined sections 13 are arranged parallel to the protrusions 4. At one end of the bark, 2 there is a hole, which houses the sleeve 14, which serves to secure the pusher 15 placed in the hole of the core 1. St p | Zhen 15 is placed inside the channel 16 formed in the core of the th-located inside the housing section 10, inside the channel 16 there is a sleeve 17 in which a plunger 18 is installed. The plunger is connected to one end of the shaft 15 and / besides spring 19 is pressed against the plunger, working in compression. When current passes along the windings, the faces of the inclined sections 13 and c) the protrusions 4 move towards each other, the movement is transmitted to the plunger 18 in the direction opposite to the spring force 19. If the windings are de-energized, then the measles, rod, pusher and plunger move under the action of spring 19, Anchor-12 is surrounded by a hollow shell: sleeve 20, made of a non-magnetic material. In order for the cover to be easily pulled out of the matrix during its manufacture, it is made tapering. Its inner and outer surface is stepped. The inner surface of the skin; ta is the stop for the core as it moves. A protrusion 21 is formed on the outer surface of the casing, and protrusions 22 are made on the inner wider part. The casing is also provided with protrusions 23 located on its tapering part. The open end of the casing is closed
    24-cup non-metallic zaglugikoy shape.
    In this embodiment of the electromagnetic device, it is also desirable that with a minimum weight the maximum displacement is ensured. This is achieved by the size of the depressions 5. Their size is chosen so that the area of the windings located in these depressions is constant over the entire length of the core.
