The invention relates to electrical engineering.

The purpose of the invention is to expand the functionality by providing the braking mode of the coupling half.

The drawing shows the proposed Electromechanical unit, a longitudinal section.

The unit contains a fixed magnet electric motor and a coupling in the form of a ferromagnetic cylinder with laminated bag 2, an alternating current winding 3 and an excitation winding in the form of ring coils 4 and 5, and covering the front windings of an alternating current. The ferromagnetic rotor b of the engine is at the same time the leading half coupling, freely mounted in bearings in the bore of the package of the magnetic circuit and lays on the teeth 7 on the inner surface. The driven coupling half 8 is made in a T-shaped cross section and is fixed on the output shaft 9. The ferromagnetic parts 1 O and J1 of its rim are magnetically insulated one from the other and from the ferromagnetic core of the disk 12 with a non-magnetic ring 13. Bearing shields 14 and 15 are made ferromagnetic and provided in the middle part with internal annular protrusions 16 and 17, on which annular ferromagnetic cores 18 and 19 are fixed with toothed layers 20 and 21 on their ends facing the middle disk wall 12 of the driven coupling 8. Bearings of the driving coupling half b mounted on the annular protrusions 16 and 17, the Toothed layer 7 can be performed on the outer side of the driven coupling half 8,

When the alternating current winding 3 is turned on, the rotor and the half coupling half accelerate at idle. The intermittent activation of the causes 4 and 5 of the excitation winding creates two magnetic fluxes, the directions of which are shown in the figure by solid lines with arrows. Gear layer 7 of the leading coupling half 6 leads to the ferromagnetic parts 10 and 11 of the rim of the driven half coupling 8 are eddy currents, the interaction of which with the flow of teeth creates a moment leading to the rotation of the driven coupling half 8 with the output shaft 9. The rotation speed is adjusted by changing Current eat in. field winding coils.

If coils 4 and 5 of the excitation winding are turned on consistently, the total magnetic flux is created, the direction of which is shown in the drawing by a dashed line with arrows. - Gear layers 20 and 21 at the ends of the cores 18 and

19 induce eddy currents in the middle disk wall 12 of the driven coupling half 8. The interaction of these currents with a fixed flow of toothed layers

20 and 21 creates a braking torque that brakes the driven half coupling 8 with the output shaft 9. The braking torque is controlled by varying the amount of current in the field winding.

The use of the proposed electromagnet of the mechanical assembly provides the braking mode of the driven half coupling with

output shaft when using a common magnetic system and a common excitation winding in clutch and brake modes. Compared to the prototype, this reduces the start and stop cycles

what's the mechanism that makes it bigger

performance. Compared with 1 known aggregates containing induction brakes with separate magnetic systems and windings

excitation, the proposed unit increases the use of ferromagnetic and conductive materials, which reduces the size, weight and cost of the device,
