The invention relates to energy and power vehicles and can be used on land, water, air and space transport.

Widely known vehicles with electric traction, running through from the mains power, this electric locomotives, trams, trolleybuses.

The disadvantages of these vehicles: requires the construction of special roads and electricity networks; limited movement because of attachment to roads and electricity networks; large energy losses during transmission through the grids and the energy transformation into mechanical energy.

Known mobile vehicle with electric traction [1]running on electricity chemical batteries, solar panel, which converts electrical energy by an electric motor during the rotation of the wheels, blades, screws, screws and other Disadvantages of such vehicles: low power, energy losses in the electric motor for rotating mechanical parts.

The closest physical entity is electrodynamic propulsion [2], containing the AC source, the inductor in parallel with tires, tightly bonded with him the anchor of the tires perpendicular to the tire inductor and connected to the AC power source. The essence of it which is the electric power of the AC source is converted directly to the driving of the transport apparatus of thrust, resulting in the anchor, the interaction of the electric current of the armature from the magnetic component of the displacement current generated by the inductor. Anchor rigidly mounted on the transport device moves the vehicle in the direction of the thrust.

The disadvantages of this thruster are large energy losses on the wave resistance of the medium between the tires of the inductor, since the specific resistance of the medium 8-10 orders of magnitude higher than the resistivity of the material of the tire of the inductor, so the thrust and efficiency are small; and the negative impact of powerful high-frequency fields on passengers and staff vehicles (this propulsion is most effective in the HF range, as well as a strong RF field of the inductor creates a big noise radio).

Task electromagnetic propulsion is to reduce the costs and negative effects of electromagnetic fields on the environment and increase efficiency propulsion.

The task is solved by the fact that the electrodynamic propulsion containing the inductor, the anchor and the AC power source according to the invention further comprises a vacuum device, filled with a working substance located therein pairs of electrodes of an electric arc, ortho the national electric field and polarizable electrodes and the voltage Converter, and the inductor is made in the form of a magnetic core with windings with a gap in which is placed the anchor, one of the windings is connected to anchor the ends of the other winding connected with polarizable electrodes, the middle point is connected to the cathode of an electric arc and is grounded, and the symmetric bends its connected to the electrodes orthogonal electric field and counter-polarizable electrodes, and a third winding connected to the AC power source and, via a voltage Converter, electric arc, and through the capacitors with the ends of the second winding.

The drawing shows a circuit implementation of the traction electrodynamic propulsion

Electrodynamic propulsion consists of electrovacuum device 1, is filled with a working substance, inside of which are the electrodes of an electric arc 2 and 3, the electrodes orthogonal electric fields 4 and polarizable electrodes 5, the inductor consisting of a magnetic core 6 and the windings 8, 9 and 10 connected to the electrodes of the vacuum device, and the magnetic gap is the anchor 7 is connected to the coil 9 through the switch K2. To start the propulsion device also includes an external AC power source 11 with the switch K1 and the voltage Converter 12. In the electrical circuit of the electrovacuum device 1 is entered, the capacitors C1 and C2.

RA is work this scheme as follows. Switch K1 is connected to the circuit source 11 AC operating frequency, for example the electrical network frequency of 50 Hz. This voltage through the voltage Converter 12, which performs full-wave rectification and adjustment of the voltage applied to the electrodes 2 and 3, between which the electric arc is ignited, ionizing the working substance (e.g., inert gas). AC voltage is also fed to the electrodes 5, United with the corresponding parts of the winding 8 of the inductor relative to the average point of zero potential. When one of the electrodes 4 a negative half-wave voltage, at this time at the other electrode positive half-wave voltage. Under the action of the positive half wave of the electrons emerging from the field of an electric arc between the electrodes 2 and 3, receives the potential of the anode of the field, pass through the hole in the electrode 4 (the formation of an electron beam method, "electron gun") and enter the appropriate polarizable electrode 5, charging (polarize) it is negative. Between the electrode 5 and the schema node with zero potential is formed by a potential difference, which in the relevant part of the coil is an electric current that creates a magnetic flux in the magnetic core 6 of the inductor. This electric current recombines into molecules (restores) the floor of the positive ions, coming to the cathode 3 of the electric arc, the atoms of the working substance is again subjected to ionization by an electric arc.

When the same electrode 4, the positive half-wave voltage, the electric current is on the other side of the winding 8 of the coil, creating a magnetic flux in the magnetic core 6 of the inductor opposite direction. In the magnetic core 6 of the coil creates an alternating magnetic flux.

An alternating magnetic flux in the magnetic core 6 of the coil due to electromagnetic induction creates in the winding 10 AC voltage converted by the voltage Converter 11 supporting an electric arc between the electrodes 2 and 3, and an external source 11 is turned off automatically.

The magnetic flux in the magnetic circuit 6 also generates an EMF in the winding 9 of the armature 7, under the action of which the armature 7 with the closure of the switch K2 is the electric current. The interaction of the magnetic field in the magnetic gap 6 coil with an electric current in the armature 7 creates a pulling force (FT), eject the anchor 7 of the magnetic gap. Swapping ends of the connection of the winding 9 with anchor 7, the vector of traction will change direction to the opposite, and vehicle equipped with such a propeller will move in the direction of the resultant force of the thrust and braking force.

For increased what I efficiency and stability of circuit operation the circuit of the inductor using the capacitors C1 and C2 tune to resonance at the operating frequency of the oscillations of the electromagnetic field.

SUBSTANCE: present invention pertains to electrical engineering and can be used in parametric machines in the electrical energy industry as electric generators and electric motors, for example on electrical power stations. The synchronous generator-compensator is a combined electrical machine, the circuit of which has an electronic frequency converter, with power corresponding to an asynchronous motor. On one axle of the synchronous generator-compensator there are series-arranged rotors of the drive motor, synchronous generator with a thyristor-type self-triggering system, and the asynchronous motor with a short-circuited rotor. The rotor of the asynchronous motor is in form of a flywheel with a large diameter, radius R and mass, which matches up the radius r and mass of the rotor of the synchronous generator, respectively, calculated using the mechanical resonance formula. The ratio R/r is chosen in accordance with the Fibonacci number sequence. The output of the synchronous generator and the input of the stator of the asynchronous motor are connected through a frequency converter, supplying the asynchronous motor with current, with discrete synchronisation of the frequency of current from the synchronous generator and frequency of the angular impulse of the asynchronous motor. The circuit of the frequency converter has massive capacitors, with provision for mechanical positive feedback from the rotor of the asynchronous motor to the rotor of the synchronous generator due to the single axle of the rotor of the asynchronous motor and the synchronous generator. The rotor of the asynchronous motor has ratio of the width to its radius in accordance with the Fibonacci number sequence, in succession to the chosen ration R/r. The diameter of the asynchronous motor is increased, corresponding to the rotor, with provision for clearance between the stator and the rotor of 1-3 mm. The method of operation of the synchronous generator-compensator is implemented, as is described in the material of the claim.

EFFECT: increased fuel saving in the drive motor, due to increase in moment of inertia on the system axle.
