    An electromagnetic device comprises first and second relatively movable support members having surfaces presented to each other, electrical conductors mounted on the surfaces respectively, each of said conductors defining a portion disposed in side by side relationship with the portion defined by the other conductor whereby when electric current is passed through the conductors the magnetic fields generated will cause attraction or repulsion of said portions thereby imparting movement to said members.

    The invention relates to electrical engineering.
    Known electromagnetic actuator containing two movable relative to each other element that are installed coaxially with each other with a gap so that the outer surface of one element faces the inner surface of another element, and the windings placed on each of the elements 1.
    The disadvantage of this drive is its low speed.
    The purpose of the invention is to increase the speed of the drive.
    This is achieved by the fact that the element is made of a non-magnetic electrically insulating material, the winding of each of the elements is made in the form of a double helix and is wound so that the current in each spiral has the opposite direction, and the turns of the winding of one element alternate with the turns of the winding of another element. Each movable element can have either a cylindrical or flat surface, and the windings to the surface of each movable element can be glued or attached.
    FIG. 1 shows an electromagnetic actuator, side view; in fig. 2 - part of the electromagnetic drive in an enlarged scale; in fig. 3 and 4 are embodiments of an electromagnetic drive.
    The electromagnetic drive contains two elements 1 and 2 that are movable relative to each other and are interconnected :( but also with a gap. Elements 1 and 2 are made of non-magnetic electrically insulating material, for example, tarred paper or cardboard.
    A winding is located on the inner surface of the element 1, which consists of two spiral windings 3 and 4. This winding can either be glued to or attached to the inner surface of the element I, but it forms a double helix. The windings 3 and 4 are interconnected in series so that the current flowing through them has opposite directions (see Fig. 2).
    A winding is also placed on the outer surface of element 2, which consists of
    two spiral windings 5 and 6, laid so that they form a double helix. The windings 5 and 6 are interconnected in the same way as the windings 3 and 4, and the current in the windings 5 and 6 has opposite directions (see Fig. 2). The arrows indicate the direction of the magnetic flux arising around each of the conductors with a current (see Fig. 2).
    From the nearby windings 4 and 5 and 3 and 6 of elements 1 and 2 it can be seen that the direction of flow to them is opposite, and therefore elements 1 and 2 are repelled from each other.
    In addition, around the windings 3 and 5 the flow has one direction, and around the windings 5 and 6 the opposite. Such a direction of flow contributes to the fact that the winding 3 tends to approach the nearby winding 5, and the winding 4 to the nearby winding 6.
    If the current in one of the windings changes, then elements 1 and 2 will move in the other direction.
    Elements 1 and 2 can be made flat (see Fig. 3), and each winding can consist of a plurality of segments connected in such a way that the currents will have the directions shown in fig. 3
    Elements 1 and 2 can be made cylindrical in shape, and each winding 3 and 4 can be made from a single piece of wire of spiral shape (see Fig. 4). The gap between turns 3 and 4 in this case is chosen large enough. The direction of the currents in windings 3 and 4 is opposite, and therefore elements 1 and 2 repel each other.
