Known rotary pulse generator containing laminated rotor and stator phase windings, connected in series through two brush-collector node, a switching power supply to generate the primary magnetic flux in the gap of the generator and the load connected in series with the stator winding is connected with the other end through the switch to the power supply [1]. The principle of operation is that when the coil windings of the rotor shown in rotation from a third-party engine, pass over, according enabled coils of the stator winding, the pulse power source through the switch discharges in series the windings of the stator and rotor and the load, creating a gap of the generator of the initial magnetic flux. When the switch is chosen so that the required value of the magnetic field in the gap was achieved by the time of finding the center pole of the rotor under the center pole of the stator. Upon further rotation of the rotor pole are the tion above the coils of the stator winding, which leads to a sharp decrease in the inductance of series-connected windings. When the rotation of the rotor, to achieve the position counter is enabled windings, there is a compression of the magnetic flux (magnetic field) to 5 - 15 TL. In the air gap and there is a powerful braking torque acting on the coil. The change in inductance leads to a proportional change in current in a circuit consisting of series-connected windings of the rotor, the stator and the load, and the evolution of a large shock power on the load. As a result, the generator allows for a short time, comparable with the time of rotation of the rotor on one pole division, to develop high impact power on the load and to give her some of the kinetic energy of the rotor.

With a sharp decrease of the self-inductance of the generator in the gap between the coils of the stator and rotor of the value of the magnetic field reaches a maximum and coils apply maximum force. In the generator windings are two main forces: in the form of radial magnetic pressure on the winding and from tangential braking torque. These forces cause the compressive stress in the windings and can be achieved depending on the power generator 400 - 200 the importance of the moment. Therefore, the mechanical strength of the material of the windings and insulation imposes a limitation on the magnitude of the pulsed power generator.

Known rotary pulse generator made according to the above principle, in the slots of the rotor and the stator of which is placed the coil-bound with bandages education explicit poles, made in layers of electrical conductor separated by electrical insulation between the turns and layers [2].

The rotor and stator of the generator recruited from the round plate with the four slots located on the perpendicular diameters. Accordingly, the projections of the plates form a pole. Each pole of the rotor and stator is surrounded by coils placed in the slots. The depth of the groove is determined by the combined thickness of the insulation of the coil is determined by the penetration depth of the magnetic field in the conductor of the coil when the compression field at the time of pulse generation. During compression of the magnetic field between the windings of the rotor and stator arises powerful braking torque, which pushes the rotor winding and stator in the tangential direction to the side edges of the groove of the rotor and the stator, thereby causing compression of the electrical insulation of the coil and the conductor. Value Dopovidi pole, determined by their mechanical strength and is within the range (3 - 8) 103kg/cm3[3]. In the traditional design of Electromechanical pulse generator with pulse capacities that are on the level (1 - 10) GW, the pressure on the side wall of each slot of the rotor and stator from the braking torque and, accordingly, the conductor and the insulation reaches (15 - 30) 103kg/cm2. The fastening of the same windings of the rotor and stator causes the well-known problems associated with the need to reduce the gap between the windings of the rotor and stator and the best possible ratio of change of inductance, which limits the free space for the location of the fastening elements of the windings.

The use of the principle of separation of windings on the part resting on the teeth of each part of the coil, for example, as turbine generators can reduce the specific pressure on the coil, because each part of the coil sees only part of the braking torque. But also reduces the shock pulse power due to the lower ratio of the change of inductance due to the deterioration in the compression of the magnetic field such partitioned coils as the magnetic field falls between parts catus generators of this type.

Similar disadvantages inherent in pulse generators, made of plastic (i.e., not having the iron of the magnetic circuit) to significantly reduce the weight of generator (2.5 - 3 times), which is very important in their application in high-power systems power available on mobile objects.

The invention solves the problem of increasing the specific pulsed power rotary pulse generators.

The invention consists in a rotary pulse generator containing a rotor and a stator, the slots which are placed in the coil, sealed tyres, with the formation of explicit poles, made in layers of electrical conductor separated by electrical insulation between the turns and layers, in which the turns of the coils of the rotor and the stator is made of a conductor rhombic cross-section and are located in a layer with a pitch between the centers of the conductor turns, exceeding the largest diagonal of the rhombus, the coils in each layer are offset from the coils surrounding layer half step; in the first layer of coils, between the groove wall and the coils, and in the last layer, between the coils and the outer brace installed liners, the shape of the gap between the coils and behind the coils on the value of the CLASS="ptx2">

In the particular case of the execution of the generator of the plastic in the area of rotor poles and stator concentrically mounted strips attached respectively to the rotor and the stator, with a total thickness equal to the difference between the total thickness of the coils with electrical insulation and the thickness of the insulating layers of fiber.

Achievable technical result is to increase the specific impulse of the power generator 3 to 5 times.

The invention is illustrated in the drawing, where Fig. 1 schematically shows a General view of the proposed generator (cross section) of Fig. 2 shows in section a section B of the winding of the rotor, and Fig. 3 shows a section in the setup concentric strips.

The rotor 1 and the stator 2 (Fig. 1) made in particular of plastic material, have four groove 3 located on the perpendicular diameters. In the grooves of the installed coil 4 of the winding of the rotor coil 5 of the stator winding, so that in the sectors between the coils on the rotor and the stator are formed explicitly pole 6. The coils 7 of the coils of the rotor and stator of the electrical conductor rhombic cross-section, surrounded by insulation (Fig. 2), are located in a layer with a pitch between the centers of the conductor coils, which is not misleadig layer half step. In the first layer of coils, between the wall 8 of the groove and the coils 7, and in the last layer, between the coils 7 and the outer band 9, installed the liners 10, the shape of the gap between the coils (in the particular case of this form is close to triangular) and behind the coils on the magnitude of the insulating layer, made of high-strength fiber 11, arranged in curved spaces between the layers of the coils. In the area of the poles 6 of the rotor 1 (Fig. 3) concentrically mounted strip 12 attached to the rotor in this area by the pins 13. The same strip installed in the area of stator poles. Conclusions the windings of the rotor and stator are connected in series through two brush-collector node (not shown) and connected to a pulsed power source. The liners 10 and the strip 12 is made of a plastic material.

To the description of the operation of dynamoelectric generator should be added that such a uniformly distributed winding in the slot 3 of the rotor 1 and stator 2, the magnetic field effectively compressicauda with a sharp decrease in the inductance of the counter included windings of the rotor and stator and does not sink for the coil (Fig. 1) as part of the magnetic field passing through the air gaps between the coils of the first layer fructure coils 4 and 5 of the rotor and stator, respectively, fully retains a magnetic field within its cross-section and provides the desired rate of change of inductance.

Power braking torque when it is crushed by the amount by the number equal to the number of conductors in the slot, which can be positioned in the groove 50 to 500 pcs. or more, if necessary. Accordingly, specific pressure of each of the conductor 7 on the mechanical structure 11 and the insulation of the conductor is reduced in proportion and can be from 600 to 60 kg/cm2. Such levels of stress withstand existing materials and insulation. The proposed form of the cross section of the conductor and the mutual displacement of the coils formed by molding and zepecki mechanical structure of plastic with a curved reinforcing fiber 11. Therefore, such a plastic keeps the inside of each conductor independently due to the curved reinforcement fiber 11. To ensure the required strength taking into consideration the cyclic action of loading for reinforcing the insulating fiber 11 is advisable to use high-modulus and high-strength glass (CM) or organic (synthetic) fibers (Fig. 2). Concentric strip 12, installed in the area of the poles of the rotor 1 and the stator (Fig. 3), compensate for the thickness of the missing coils in the area of the poles and ensure the preservation of the mechanical strength of the rotor, the stator and the fibrous structure of the slot portion in case the ke is low due to the load distribution over the cross section of the groove and the absence of her summation over the whole cross section of the coil when it is traditional in a tightly Packed coils, transferring the load to each other. This principle of design of the coil was mechanically tested on the model and confirmed the validity of such proposals. Thus, achieves the required mechanical strength of the rotor and stator and substantially increases the shock pulse power generator.
