Description

ELECTROMECHANICAL SYSTEM

The proposed device relates to electromechanical systems designed both for mechanical work and for generating electricity.

The well-known "ELECTROMECHANICAL CONVERTER" US 2005077800 [2], equipped with a primary shaft having a rotor, a secondary shaft mounted thereon, having a secondary rotor mounted on it, and a stator fixedly mounted in the housing of the electromechanical converter.

The disadvantage of this device is the inability to generate electricity.

The closest technical solution is the "ELECTROMECHANICAL VARIATOR" RU PM 102438 [1], containing a generator and an electric motor having an excitation winding that is electrically connected to a current source, one armature common to the motor and the generator, the motor winding is provided with a first collector-brush assembly , which is electrically connected to an external DC source, the device contains a second collector-brush unit, used, including for removing electricity from the anchor.

The device has the ability to generate electricity due to the presence of a second collector-brush assembly.

The disadvantage of this device is the low energy efficiency of the device due to losses in the double inductor. The disadvantage is the increased complexity and low overall dimensions.

The technical result of the invention is to increase energy efficiency, simplify the design, improve the overall dimensions of the device.

The technical result is achieved in that the electromechanical system comprising a generator and an electric motor having an excitation winding that is electrically connected to a current source, one armature common to the motor and the generator, the motor winding is provided with a first collector-brush assembly that is electrically connected to an external source DC, the device contains a second collector-brush assembly (used, including for removing electricity from the armature), characterized in that the motor windings I and the generator are located in a single anchor located on a single shaft (on a rotor having a single shaft), the device has a single stator with a single field winding.

A single shaft of the engine and generator can be connected to a mechanical load pulley, which will allow the engine to perform mechanical work.

The system may include an additional set of brushes on the generator manifold. An additional kit will allow you to remove additional energy from the rotor of the device.

A single shaft of the engine and generator can be connected to the flywheel. The flywheel on the shaft of the electromechanical system smoothes out the uneven rotation of the shaft and is the accumulator of the mechanical energy of the system.

The system may include an electric control unit and conversion of electrical energy with input and output terminals, which will optimize the operating modes of the system.

An electromechanical system made using PP 1-5 is shown schematically in Fig., Where:

1 - stator with field winding;

2 - anchor with windings;

3 - collector of the first collector-brush assembly;

4 - a set of brushes of the first collector-brush assembly;

5 - collector of the second collector-brush assembly;

6 - the main set of brushes on the collector of the second collector-brush assembly;

7 - an additional set of brushes on the collector of the second collector-brush assembly;

8 - flywheel;

9 - mechanical load;

10 - control unit and electric power conversion;

11 - input terminals;

12 - output terminals.

The device operates as follows: the electromechanical system contains a stator 1 with an excitation winding, inside which an armature 2 with windings is rotatably placed, one is connected to the collector of the first collector-brush assembly 3, the second to the collector of the second collector-brush assembly 5. To simplify the drawing electrical connections are shown in one line. Incoming electricity is supplied to. At the entrance to the system, a constant current is supplied to the set of brushes of the first collector-brush assembly 4 of the engine, which drives the system. In the case of connecting the system shaft with a mechanical load pulley 9, (for example, with a car wheel), the system operates both in a mechanical load mode and for generating electricity. The generated electric power supplying the electric load is removed from the main set of brushes 6 of the second collector-brush assembly. In the case of installing an additional set of brushes 7, additional electric power will be removed from them to power the electric load. The control unit and energy conversion 10 will optimally distribute electricity between the input terminals 11 and output terminals 12.

The flywheel 8 on the shaft of the electromechanical system smoothes out the uneven rotation of the shaft and is the accumulator of the mechanical energy of the system.

The system makes up for electric energy due to the energy removed from the main set of brushes, due to the additional set - it gives additional electric energy.

Due to the flywheel, the system can work for a long time in stand-alone mode, generating additional electricity. Also, long-term work in standalone mode will be facilitated by electricity removed from the additional kit, supplied to the primary winding.

If at the same time the shaft rotation speed does not decrease, then you can not connect to external power sources.

EFFECT: increased energy efficiency is achieved by reducing energy losses due to fewer conversions.

Industrial application. The utility model can be successfully applied in the manufacture of electromechanical systems.
