Description

The invention relates to electrical engineering, to electromagnetic vibrators, and can be used in many areas of engineering and technology when creating mechanical vibrations.

The goal is to extend the functionality by providing dual frequency oscillations.

Fig. I shows the structure of an electromagnetic generator of mechanical vibrations; Fig. 2 is a circuit for turning on generator windings.

The electromagnetic generator of mechanical oscillations (FIG. 1) contains a cylindrical body 1, an additional body 2j mounted coaxially with it, rigidly connected to the body 1, the body 1 has 3.4 loop magnetic windings and excitation 5.6, the body 2 has a laying - on the additional annular winding 7 of the excitation, In cases 1 and 2, measles are placed coaxially with them, consisting of a main 8 and an additional 9 5 EGMK in various vibrating devices

parts interconnected by a bolt 10; With respect to cases, measles has an elastic suspension in the form of two disk diaphragms 11 and 12; On case 1, the flange 13 of the generator is fixed. The windings 3 and 4 magnetizations are connected in series oppositely (Fig. 2), and the windings 5-7 of the excitation are consistently consistent.

The device works as follows.

When a constant voltage is applied to the windings 3,4 of the magnetizations, connected in opposite directions, a magnetic flux arises, which closes along the core and the housing 1. At the same time, the same magnitude electromagnetic forces act on the measles,

as a result, measles remains in alternate oscillations, coaxially to the main equilibrium body. The excitation windings 5-7, connected in series according to, are supplied with alternating voltage, resulting in a variable magnetic flux, which

An additional body of an annular field winding and a core are rigidly connected to the main crust, and the field windings are connected in series.

On the one hand, housing 1 is collapsed with the bias flow, and on the other hand, it is subtracted from it. As a result, the resulting electromagnetic force acts on the measles, which varies with the frequency of the supply network.

Under the action of the magnetic flux of the additional winding 7 excitation

measles is affected by electromagnetic force. The variable component of this force has a double frequency compared to the frequency of the mains supply. Thus, measles are simultaneously acted upon by electromagnetic forces having a frequency of the first and second harmonics when the excitation windings 5-7 are energized by the current with the frequency of the first harmonic. .

The installation of the additional housing 2 and the excitation winding 7 makes it possible to obtain an electromagnetic generator of mechanical oscillations (EHMK) of double frequency. The use of such
