Common to these known rotary engines is the use of permanent magnets. The mentioned engines have a small moment on the shaft and a very low speed of rotation, so they were not widely used in power generation.

A known permanent magnet motor-generator (pat. О52010/0013335 АТ, НО2К 21/00, publ. 01.21.2014), which has an armature, and the stator is fixed in a position with the possibility of free movement of the rotor between the armature and the stator. The invention is directed to a method of using unbalanced unbalanced magnetic fields to induce rotational motion in the rotor, the rotor moving relative to the armature and the stator. The device implements the use of unbalanced magnetic fields formed by permanent magnets of different strengths to induce rotational motion.

The disadvantage of such devices is that, as bipolar systems, they do not have their own energy capacity and therefore are able to function only by consuming external energy flows.

A known electromagnetic generator without moving parts (05 6362718, publ. 26.03.2002) comprising a permanent magnet and a magnetic core including first and second magnetic paths. The first input coil and the first output coil pass around the sections of the first magnetic path, while a second input coil and a second output coil pass around portions of the second magnetic path. The input coils are alternately pulsed to provide pulses of induced current in the output coils. The movement of electric current through each of the input coils reduces the flux level from the permanent magnet within the magnet path around which the second input coil In an alternative embodiment

From an electromagnetic generator, the magnetic core includes annular spaced plates, and racks and permanent magnets alternate between the plates. The output coil is located around each of these connections. The input coils passing around the plate portions are pulsed to induce current in the output coils.

Energy systems built on such a generator, in the system of polar relations, are built according to the principle of consecutive binary chains forming a pseudo-ternary system. The disadvantage of such devices is that they have a small amount of excessive energy.

The closest in terms of technical features is the magnetoelectric motor |ВО 2515999,

НО2К 21/24, publ. 20.05.2014), the rotor of which contains a disc fixed to the shaft, on which is placed a ring-shaped series of permanent magnets, the polarity of which alternates, and the stator contains two plates parallel to each other, between which the stator windings are placed, the stator plates are equipped with cores made of electrical engineering steel, on which the stator windings are placed, the cores are made in the form of rings, the surfaces of which face each other have protrusions, the width B of the protrusion is half the width C of the permanent magnet, the protrusions of one of the cores are shifted around the circumference relative to the protrusions of the second core by half the width C of the permanent magnet, while the rotor disc is placed between the cores of the stator windings.

The disadvantage of the prototype is the low rotation speed and material consumption.

The useful model is based on the task of improving the motor-generator by changing the design of the rotor and stator, to ensure energy saving and environmental cleanliness when obtaining mechanical and electrical energy in energy-saving and autonomous modes.

The problem is solved by the fact that in a tripolar disk motor-generator, the rotor of which contains a disk of magnetic material fixed to the shaft, in which permanent magnets are rigidly fixed, stators of magnetic material, on which the stator windings are placed, while the rotor disk placed between the stators, according to a useful model, the poles of the rotor's permanent magnets are opposite and form 120" sectors of different polarity in the rotor, and may also contain more than two stators.

The essence of the proposed useful model is explained by the drawings, where: fig. 1 - the construction of a tripolar motor-generator with execution options (a and b) according to the angular displacement of the stators;

fig. 2 - detailed design of a disk tripolar magnetic rotor with an example of the location of an additional stator; fig. C, fig. 4 - electrical circuits of a tripolar motor-generator.

The disk tripolar motor-generator (Fig. 1) is made in a single monobloc design and contains at least two stators 1 and 4 with working windings 2.

Tripolar disk magnetic rotor 3, fixed on the axis and located between stators 1, 4 with windings 2. Stators 1, 4 are made of magnetically soft material and have the shape of a ring with protrusions located at an angle of 120". Other parts of the motor-generator (body , shaft and power electronics) are not shown in the drawings, as they are not new and do not require additional research in this area.The concept and design of the electronics is well known in the field of power generation.

Variants of execution according to the angular displacement of the stators 1, 4 are presented in fig. and - mirror or in-phase and Fig. 16 - quasi-mirror or anti-phase, can be used when connecting a tripolar disk motor-generator to a three-phase power supply network.

Synchronous switching of stators 1 and 4 doubles the mechanical power of the tripolar disk motor-generator in motor mode.

Anti-phase switching of stators 1 and 4 is used to switch on the tripolar disk motor-generator in the generator mode.

In the tripolar motor-generator, a natural synchronized redistribution of magnetic fluxes is carried out in the process of induction-self-induction of the three-section working winding 2, which forms a unidirectional resultant torque of the magneto-mechanical force, which leads to the continuous rotation of the tripolar magnetic rotor 3. The working energy environment necessary for its operation , is a tripolar electromagnetic field, which is formed in the dynamic mode of operation of this motor-generator.

To create a tripolar electromagnetic field, a closed stator magnet wire 1, 4 with three separate pole tips is used, in the interpolar space of which a tripolar magnetic rotor 3 is located. The stator magnet wire 1, 4 contains three independent working windings 2, which create a single electromagnet that is switched on

From a sector of 240" or 120".

When an alternating electric current is applied to the working winding 2 in the 240" sector, an asymmetric torque acting on the tripolar magnetic rotor 3 occurs. The torque operates within 240". That is, for 2/3 of the angular path, the system builds up its energy independently.

This is the internal energy of the system. To overcome 1/3 of the angular path, the working winding 2 is turned on as an electromagnet by sector 1207, which creates a condition for the continuous rotation of the tripolar magnetic rotor 3. By fulfilling the condition of synchronous introduction of the electromagnet into the system by sector 1207, we get an energy source with a unique property - cost-free energy reproduction .

In the operating mode with a connected load, the following energy relations are performed for the tripolar motor-generator:

MMo-MU/v--MUx, (1) 1-M/v/Mo-Mukh/Mo, 1/3 2/3, where (2)

Mo is the energy capacity of the tripolar motor; M/v - internal (self-sustaining) energy;

Flies - excessive (external) energy.

The energy capacity of a tripolar motor-generator consists of 3 1 parts of self-occupied (internal) energy, necessary to maintain its viability, and 2 parts of excess (external) energy that can be used to perform useful work.

Initial start-up is required to remove part of the energy capacity in the form of mechanical energy. From the moment of initial start-up, the motor-generator begins to build up its energy capacity to its maximum value. The magnitude of the energy capacity is determined by the power of the magnets of the tripolar magnetic rotor З and the energy characteristics of the magnet wire of the stators 1, 4 and the working windings 2, as electromagnets.

To expand the possibilities of connecting a tripolar motor-generator in the combined mode of production of both mechanical and electrical energy, additional stators 5 are introduced into the structure (Fig. 2).

The duration of continuous operation of the motor-generator in autonomous mode after the initial start-up is determined by the lifetime of the rotor magnets.

Example 1. 60 Operation of a tripolar motor-generator is possible in three modes:

1. In the mode of generating mechanical energy.

The implementation scheme of the motor-generator in the mode of generating mechanical energy is shown in Fig. 3.

Three sections of the excitation winding with inductance I! are connected in series and form a single electromagnetic system. The process of induction and self-induction of each of its sections is automatically synchronized with the rotation of the tripolar rotor P. The fields of induction and self-induction form the resulting magnetic field of rotation, which leads to a constant increase in the speed of rotation of the tripolar rotor P until it reaches the maximum kinetic energy, which is determined by the energy parameters of the magnets of the rotor P and coils of inductance I, as well as the magnetic resistance of the magnet wire Km. 2. In the mode of generating electrical energy.

The scheme of implementation of the motor-generator in the mode of generating electric power is shown in Fig. 4. Unlike the scheme of fig. 3, on top of each section Y, the winding of connection I zv is wound, designed to divert the electrical energy applied to it to the external load. To exclude the mutual influence of the coils of the connection Izv by alternating current, each coil of the connection is loaded on a two-semi-periodic diode bridge KD. The outputs of the diode bridges of the CD are connected in parallel and connected to the output terminals of the tripolar motor-generator intended for connecting an external load (external direct current consumer). 3. It is possible to implement a combined mode of operation - simultaneous generation of both mechanical and electrical energy.

The presence of additional independent stators 5 with independent working windings 2 (Fig. 2) allows the simultaneous combination of two modes of operation: the mode of the electric motor when external electricity is supplied to the contacts 5) (Figs. 3, 4) and the mode of the electric generator, in which electricity is removed from winding of the stators, which are not involved in the implementation of the motor mode.

The combination of opposite functions - motor and generator modes - opens the way to the creation of highly efficient energy systems, the construction of which is inaccessible to traditional scientific and technical solutions.

The use of electronics or a programmable controller to control the commutation of the working windings of 2 stators 1, 4, 5 will allow to increase the efficiency of using the resource of the tripolar disk motor-generator.

Example 2.

As one of the examples of the use of a tripolar disk motor-generator, we will consider the possibility of its operation from an industrial three-phase power grid. In this case, the stator windings are connected according to the star scheme, and for the operation of the motor-generator in the electric motor mode, it is enough to engage only one stator 1. Connecting the second stator 4 allows you to get new functionality. With the synchronous connection of the second stator 4 (Fig. 1, a), the power of the motor-generator in the electric motor mode is doubled. When the second stator 4 is switched on against the phase, we switch to the generator mode, when the external three-phase energy spent on the operation of the electric motor is supplied to the working windings of one stator 1, and from the windings of the second stator 4, we have the opportunity to remove secondary generated electricity from the load. In this mode, a significant increase in the efficiency of the use of external energy is expected, which is spent not only on obtaining mechanical energy from the electric motor, but also on obtaining secondary electrical energy from the electric generator, the role of which is performed by anti-phase stator 4. In the proposed switching schemes, stators 1 and 4 are interchangeable.
