(54) POLARIZED ELECTROMECHANICAL CONVERTER FOR ELECTRIC HOURS

The invention relates to a time device i, in particular to polarized aptromechanical converters for electric clocks. According to the main author. St. No. 686OO8 is a known polarized electromechanical converter for electric hours, which contains a serrated rotor, a pole-pole stator With a control winding and a permanent magnet located in the container. The control winding of the converter is made sectioned on ferromagnetic cores and placed in a plane, perpendicular to the rotor axis l}. The disadvantages of the known converter are the relatively low level of useful power per unit volume and weight, as well as the complexity of the design and manufacturing technology. The small level of useful mobility is due to insufficient use of the air gap area, since only a small part of the active rotor teeth area is involved in creating the moment on the shaft. The complexity of the design and low-tech due to the large number of composite parts of the magnetic circuit. The purpose of the invention is to increase the effective power per unit volume and weight of the converter while simplifying the design and improving the processability. The goal is achieved by the fact that the converter is rotated with a rotor, the width of the KoTOpioro tine is equal to the tsphine of each of the two poles of the stator and is 150-17 ° O, and each of the poles of the stator is connected to one of the two winding cores with parallel axes closed between each other by ferromagnetic jumper from the side opposite the stator poles. FIG. I is represented by a converter; in fig. 2 - the same, В1Зд from the end of the rotor; in fig. 3 the same view from the back.

On c: n 1, the popopus rotor 2 is rigidly fixed, the pole-shaped tooth 3 B is shaped like a blade, a disk part is bent away from eix and a magnet 4 coaxially located with the rotor 2 that is axially magnetized. The control winding is made sectioned and includes coils 5 and 5 on ferromagnetic cores 6 with pole shoes.

7 with the poles 7. The axes of the coils 5 and b are located in the plane perpendicular to the axis 1 of the v-pole rotor 2. Coaxially with the rotor 2, a profiled plate 8 made of ferromagnetic material is installed, playing the role of the rotor retainer 2 in the pauses between the pulses. The cores 6 are interconnected by a ferromagnetic jumper 9.

The Converter operates as follows.

When a current pulse is applied to the winding, a magnetic field is created, the Korqjoro power lines are compressed through the cores of 6 coils, pole shoes 7, the gaps between the tooth 3 of the rotor and the rotor disk.

Depending on the polarity of the current pulse, in one case the magnetic fluxes of the control winding and the permanent magnet 4 are added, and in the other case the magnetic fluxes are subtracted.

As a result of this, a rotating torque arises, turning the rots 2 in the direction of the greatest magnetic conductivity. At the end of the current pulse, the rotor 2, rotating under the action of the reactive moment, due to the presence of the latch 8, passes into the following

steady state. The cycle then resumes.

The rotor pitch at each current pulse is 180. This ensures an increase in the useful power on the shaft, since almost half of the rotor circumference is occupied by a dentate zone, which is directly involved in creating the useful moment. In addition, the effectiveness of the invention lies in the simplification of the construction and improvement of the processability of the polarized electromechanical generator.
