FIG.

The invention relates to electrical engineering and can be used in exams where it is necessary to ensure the spatial movement of a working organ.

i The aim of the invention is to obtain spatial movement.

FIG. 1 and 3 schematically shows a conical washer with traction electromagnets; in fig. 2 - section A-A 1-: and FIG. one; in fig. - electric motor engine.

At the base of the conical ferromagnetic washer there are four cylindrical traction electromagnets 1–4 located symmetrically with respect to the axial bore 5.

The electromagnetic engine consists of fourteen washers 6-19 (Fig.4-6). The washers are connected by an elastic tensioned cable 20 fixed on the outermost beams 6 and 19 and passing through the axial holes of the washers,

The ferromagnetic washer 6 is a retainer. When it is energized by electromagnets, it is attracted to the ferromagnetic base 21, Ferromagnetic washer 19 is a working body.

The electromagnetic motor operation em as follows.

A voltage is applied to the electromagnets of the washer 6, and, attracting the ferromagnetic base, it fixes the base of the engine. Then, if the voltage is applied to the left relative to the elastic cable, the electromagnet TJb washers 14, 16, and 18 and the right electric cables are (relative to the elastic grooves 7-13, 15, 17, and 19, then Rain washer 19 will take the position shown in Figure 4. If you power only the right electromagnets of all the sheyb, the washer 19 will take the position shown in FIG. 5, You can apply the power to the left electromagnets of the | ib 13 -19 and right and left electro-connectors of washers 7-12, then the working op ™ hin 19 will take the position, represented by the one in FIG. 6, “Thus, the switch | yucha right and left electromagnets can be made to move a working organ in the plane of the drawing. H0 each washer has an electromagnet ring, therefore, an interchangeable body is possible in a plane perpendicular to the plane of the drawings (Figs. 5 and 6). spatial positions of the working body (e.g.

FIG. 7 and 8).

The number of different spatial positions of the working body of such an engine is very large. In general, it is calculated according to the following

formula

one-.

where n is the number of different spatial positions of the working body;

k is the number of electromagnets located at the base of the washers; i - the number of washers. For the engine, this number is

those. a number greater than 67 million. Thus, the present invention allows to simplify the obtaining of spatial displacements of the engine operating unit without using mechanical reduction, to ensure high positioning accuracy, ease of control of the engine from microprocessor controllers, with which the engine is easy due to its design. matching formula A stepper motor containing a ferromagnetic base on which an electromagnetic is located a retainer associated with an electromagnetic displacement mechanism, characterized in that, for the purpose of spatial displacement, the electromagnetic displacement mechanism is equipped with conical ferromagnetic washers with an axial bore, around which cylindrical traction electromagnets are placed, and an elastic non-magnetic cable, Second, conical washers with the specified traction electromagnets are strung through an axial hole, and conical washers adjacent to it, one extreme washer, are used as the Korean traction electromagnets. used as a lock and. An elastic cable is rigidly fixed on it, the other end is rigidly fixed to another extreme washer.
