The pneumatic motor includes a housing 7 with the lower support plate 8 having holes for mounting, closed the back cover 9 and the front cover 10 made of aluminum alloy or other non-magnetic material. The front cover of the spherical shape is made with a cylindrical part and the end part of the hollow hollow glass 11, into which is inserted the excitation coil 12 of the generator of electric current, which is the front pillar rotor installed inside the housing, having an inlet 13, the outlet 14, 15 safety valve and manometer 16. Cover sealed with gasket 17. On the cylindrical part of the front cover worn and fastened to the stator of the generator of electric current. It contains all the housing 18 with a hole in the center, saety coil 21, interconnected in series and connected to the input of the relay-regulator 22, the output of which is connected with the input of the rectifier 23. The output of the rectifier is connected to the terminals 24 DC, which also is connected above the excitation coil. Terminals 25 single-phase alternating current is connected to the relay output control. The rotor pnevmaticheskogo engine, also made of aluminum alloy or other non-magnetic material, made in the form of a cylindrical body 26 having in the rear part of the neck 27 of the bearing. In the front part of the rotor having end opening 28, are mounted two permanent magnet 29 and 30, made in the form of a round combs, the teeth of one are included in the intervals between the teeth of the other. The rotor contains the deaf, opening away from the axis of rotation channels 31 and 32 of rectangular or circular cross-section, located in rows along the longitudinal axis of the rotor, and in each row there are two channels that are deployed relative to each other by 180 degrees. At the bottom of each channel by bolts 33 fixed triangular inserts 34 in such a way that the plane of the bottom of each pair of channels is at an angle to a line passing through the center of rotation and separating the two in the casing 35, in which the cylinders 36 and 37, into which are inserted the pistons 38 and 39 connected by a rod 40 having a finger 41 which is connected with a plug 42, mounted on a shaft 43 having a handle 44.

The cylinders are closed by caps 45 and 46 having inlet valves 47 and 48, loaded springs. The internal cavity of the cylinder through the exhaust valves 49 and 50, the channel 51 is connected to the fitting 52, which through pipe 53 through the inlet valve on the motor housing is connected with the inner cavity pnevmaticheskogo engine.

Work generator

Before starting the generator set must be inspected and make sure that all nodes are in good condition. To start the generator set required by a pneumatic pump 5 submit through the pipe 53 into the housing 7 of the engine compressed air and bring the pressure up to 25 - 30 kg/cm2by moving the handle 44 to the right and to the left. The shaft 43 oscillates magic cube MOV is the GUI side. Air is drawn in through the intake valves 47 and 48, and through the exhaust valves 49 and 50 is pressed into the motor housing. Once the air pressure reaches the required value (determined by the readings of the pressure gauge 16), the rotor pnevmaticheskogo motor will rotate. Rotational moment is generated on the rotor as follows. Compressed air enters the channels 31 and 32. Eject force of Archimedes, the current in gases as well as liquids, produces pressure on the side walls and the bottom of each of the channels 31 and 32. Since the square of opposite walls equal as l = l1; l2= l3; l4= l5then the forces acting on these side walls are also equal and balance each other F = F1; F2= F3; F4= F5(Fig. 8 and 9). Forces Fpand Fp1acting on the bottom of each of the channels, nothing is balanced and form shoulders forces l6and l7attached to the rotor on both sides of the axis of rotation, in opposite directions. These forces cause rotation of the rotor of the motor. External forces Fnacting on the outer surface of the rotor, do not hinder the rotation of the rotor and do not create additional torque, because the action vectors of Etela determined by the pressure of compressed air, the number of channels and their sizes. During rotation of the rotor with him rotate the magnets 29 and 30, the magnetic field which is periodically moved in opposite directions by the magnetic circuit 20, and passes through the coils of the coils 21, inducting them in single-phase AC current. The resulting current is fed to the input of the relay-regulator 22, which supports its parameters depending on the rotor speed. Next, an alternating current is supplied to the rectifier 23, where it is rectified and supplied to the terminal 24 to the consumer. From the same terminal part of the DC is removed and fed to the excitation coil 12. During the passage of current through the excitation coil is formed around it a constant magnetic field, which increases the effect of magnetic fields of permanent magnets 29 and 30 mounted on the rotor. The increase or decrease of current supplied to the excitation coil, reduces or enlarges the current produced by the generator (in the drawing, the current control generator, not shown). If the user required single-phase AC current, the connection is made to terminals 25. Leakage of compressed air through the strip 17, it must be replenished by a pneumatic pump 5. To reduce the frequency Bradenton from the housing cavity pnevmaticheskogo engine partially or completely. To increase the rotor speed to increase the quantity of air supplied into the motor housing, respectively increasing pressure. When exceeding the normal air pressure in the motor housing, the excess amount of air is discharged through the pressure relief valve 15. The control generator set is carried out by remote control 6.
