l SUMMARY OF THE INVENTION

The objective of the invention is to create a power plant of a closed cycle with a high output power rate, zero level of emissions and low cost of exploitation due to using no external sources of energy like fuel, heat, sunlight, wind or kinetic power of water.

According to the invention, the power plant as claimed in the claims achieves this object due to using innovative direct current electric motors and innovative arrangement of the parts of the power plant.

The power plant comprises an electric power generator, a direct current motor with a powered armature or a direct current motor with a powered stator, a mechanical transmitter to transmit torque from the DC motor shaft to the power generator shaft, an accumulator battery or a set of batteries, a charger meant to charge the accumulator battery, a switchgear meant to distribute current of the electric power generator among the DC motor, the charger and power consumers, wherein the switchgear is designed to have an input for electric power produced by the electric power generator, the first output for current supply to the DC motor input, the second output for current supply to the charger input and the third output for current supply to electric power consumers, wherein the elements of the power plant are electrically connected so that the output of the electric power generator is connected with the switchgear input, the first switchgear output is connected with the DC motor input, the second switchgear output is connected with the charger input, the third switchgear output is connected with the electric power consumers and the charger output is connected with the accumulator battery or a set of batteries.

The power plant works as follows, electric current from the battery or a set of batteries is transmitted to the direct current electric motor. Due to the specific design of the motor the amount of consumed power is significantly lower than the output rate. The torque is transmitted mechanically from the shaft of the DC motor to the shaft of the electric power generator. Than the generated power is distributed among the consumers of electricity and the recharger. Once the power plant works stably the switchgear transmits a part of the generated power to the DC motor and the battery or batteries are recharged by the recharger. The power plant's work is based upon the difference between the amount of electric energy consumed by the Direct Current electric motor and the amount of kinetic energy produced by the motor and then transmitted to the electric power generator to be transformed into electric energy. Two kinds of direct current electric motors are meant to be used in the power plant - a direct current motor with a powered armature and a direct current motor with a powered stator. The direct current electric motor with a powered armature is designated to comprise a motor case, an accommodated armature, a stator and pairs of contact brushes and the armature comprises a shaft, bearings, solenoids or electromagnets, contacts of solenoids or electromagnets, fixing elements to fix the solenoids or electromagnets on or in the armature so that they are equally spaced from the shaft and their assumed longitudinal axes are parallel to the assumed longitudinal axis of the shaft and the distance between the assumed longitudinal axes of all pairs of adjacent solenoids or electromagnets is the same, wherein the fixing elements are made of a dielectric and diamagnetic material and fixing elements rigidly mounted on the shaft and arranged so that their planes are perpendicular to the assumed longitudinal axis of the shaft and the stator comprises at least one pair of permanent magnets and the permanent magnets can be in the shape of such bodies as a disc, a cylinder, a spherical segment, a ring, a semi ring, an arc or a torus, wherein every pair of the permanent magnets is arranged coaxially, one permanent magnet near every flattened fixing element so that the permanent magnets are oppositely poled; every pair of the brushes is mounted near the flattened fixing elements so that every brush contacts solenoids or electromagnets contacts.

The direct current electric motor works as follows, electric current is transmitted from the battery or a set of batteries to brushes. The solenoids or electromagnets contact the brushes and magnetic field is excited in them. The poles of the permanent magnets interact with the magnetic fields of the solenoids or electromagnets. Powerful permanent magnets repel the like poles and attract the unlike poles. So, in a position of an electromagnet or a solenoid is in between two unlike poles of permanent magnets, it is repelled by one pole and attracted by the other one. In the position closest to the unlike of a permanent magnet the solenoid or electromagnet, say - electromagnet 1 , unlocks contact and becomes electrically neutral while the next-in-line solenoid or electromagnet, say - electromagnet 2, is attracted by the permanent magnets at the same time causing the armature's revolution. In the course of the revolution the electromagnet 1 contacts the next-in-line pair of brushes having opposite polarity and in its coil is excited a magnetic field of opposite polarity. The poles of electromagnet 1 and the poles of the closest permanent magnets become like poles and cause bilateral repelling. When electromagnet 1 reaches the position between magnetic fields of neighboring pairs of permanent magnets it is affected by two forces at the same time - repelling and attraction. In this variant the most efficient embodiment of the invention may include permanent magnets in the shape of semi rings to provide a continual exposure to the magnetic fields of permanent magnets and smooth character of revolution of the armature. In order to reduce friction, sparking and heating of contacts the latter are recommended to be manufactured in the shape of slip-rings or slip-rolls. It is obvious for a person skilled in art that permanent magnets can be positioned not on both sides of the armature but on one side. But in this variant the bearings will have additional load because of misbaianced armature and it will cause uneven wearing out of the bearings and misbaianced work of the apparatus. The total capacity of the motor is the sum of capacities of the armature and the stator magnetic fields. Powerful permanent magnets can have very high capacity rate. This value does not correspond to the weight of magnets. For example, a magnet, capable to hold a weigh equal 100 kilograms when applied to a lever 1 metre long has a mechanical effect equal 9800 Newtons. A pair of magnets has a double effect. The said pair of magnets will effect any electromagnet if its mass and the mass of the armature and the level friction is lower than this value. So an electromagnet can consume an amount of electric power enough to generate a minimal efficient magnetic field.

The direct current electric motor with a powered stator comprises a motor case (8), accommodated armature in the shape of a flanged bobbin (16), a stator (17) and at least one pair of solenoids or electromagnets (14), wherein the armature comprises a shaft (12), bearings (13) and two circular rows of permanent magnets which are arranged on the flanges coaxially and oppositely poled and the permanent magnets can be the shape of such bodies as a disc, a cylinder, a spherical segment, a ring , a semiring, a torus or an arc; the stator includes at least one pair of solenoids or electromagnets and electromagnetic sensors rigidly mounted on at least one stator holder (18). The stator is fixed between the flanges of the armature which can revolve freely and the permanent magnets in the armature are equally spaced from the shaft and their assumed longitudinal axes are parallel to the assumed longitudinal axis of the shaft and the distance between the assumed longitudinal axes of all pairs of adjacent magnets is the same and the armature and the stator. The said motor works as follows, when electric current is transmitted to the coils of, say, the first solenoid or electromagnet of the stator a magnetic field is generated in them. The unlike poles of the magnetic fields of the solenoid or electromagnet attract unlike poles of the permanent magnets of the rotor and repel the like poles. When a pair of permanent magnets reaches the closest position to the unlike pole the rotor position sensor (not shown) breaks the contact and the solenoid or electromagnet becomes electrically neutral. At this moment the next-in-line solenoid or electromagnet is switched on to have a polarity attracting the first pair of permanent magnets while the first solenoid acquires the opposite polarity. The switchgear switches solenoids or electromagnets of the stator in turns changing their polarity for opposite one. For a person skilled in art it is obvious that the rotor can have more than two electromagnets or solenoids to provide a smooth manner of rotation. The said variant of embodiment has certain advantages comparing to the direct current motor with a powered armature - it has a smaller number of friction parts and sparking can occur only inside the switchgear.

For a person skilled in art it is obvious that both variants of the said power plant can be used in all known spheres of engineering as sources of electric power. It should be noted that the direct current electric motors claimed as parts of the power plant can be used in other fields of electric engineering - in industry, in transport sphere and others.

The main advantage of the said power plant is that requires no external sources of energy like fuel, sunlight, wind or water. It produces no emissions into the atmosphere. It is simple in operation and service. In both variants batteries should be changed periodically as well as friction parts - brushes in the DC motor with a powered armature, contacts in the DC motor switchgear. The power plant has a limited temperature range for efficient work of permanent magnets, so it has to be used and transported considering this fact.
