Description

The invention relates to the field of electrical engineering and can be used in electric vehicles, electromechanical control systems, for generating electrical energy, as well as for recharging an autonomous power source.

Magnetoelectric motors and generators with a magnetic rotor built on the principle of arranging permanent magnets on the rotor in such a way that their polarity alternates are known.

There are known foreign electromagnetic engines that use the repulsion and attraction of both electromagnets and permanent magnets as driving forces (Patents СМО87102256, 85103467.

EC 2553239, etc.).

Common to these known rotary engines is the use of permanent magnets. The mentioned motors have a negligible moment on the shaft and a very low speed of rotation. Therefore, they have not found wide application in energy.

The well-known permanent magnet motor-generator (pat. 052010/0013335 A1, НО2К 21/00, publ. 01.21.2014) has an armature, and the stator is fixed in 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.

The known electromagnetic generator without moving parts (5 6362718, publ. 26.03.2002) includes a permanent magnet and a magnetic core, which includes the first and second magnetic paths. The first input coil and the first output coil pass around the portions of the first magnetic path, while the second input coil and the second output coil pass around the portions of the second magnetic path. The input coils are alternatively pulsed to provide pulses of induced current in the output coils. The movement of electric current through each of the input coils reduces the level of flux from the permanent magnet within the path of the magnet around which the second input coil passes. 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 characteristics is the magnetoelectric motor (VO 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 basis of the invention is 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 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 is placed between the stators, according to the invention, the rotor disk is divided into three sectors of 120, one of which is unmagnetized, and the other two are magnetized in opposite directions, and may also contain more than two stators on which the windings of electromagnets are located.

The essence of the proposed invention is explained by graphic materials, where:

Fig. 1 - The design of a motor-generator with a three-sector rotor with options for the angular displacement of the stators;

Fig. 2 - Detailed design of a disk magnetic rotor with a three-sector rotor with 60 example of the location of an additional stator;

Fig. C - Electrical diagram of a motor-generator with a three-sector rotor;

The disc motor-generator with a three-sector rotor (Fig. 1) is made in a single monobloc design and accommodates at least two stators 1 and 4 with working windings 2.

Disk magnetic rotor C, fixed on the axis and located between stators 1, 4 with windings 2. Stators 1, 4 are made of a magnetic 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 because 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 power generation industry.

Variants of execution according to the angular displacement of stators 1, 4: presented in fig. 1, a) - mirror or in-phase and fig. 1, b) - 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 motor-generator with a three-sector rotor, 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 resulting torque of the magnetic-mechanical force, which leads to the continuous rotation of the magnetic rotor 3. The working energy environment necessary for its functioning, there is an electromagnetic field that is formed in the dynamic mode of operation of this motor-generator.

To create an electromagnetic field, a closed stator magnetic wire 1, 4 is used with three isolated pole tips, in the interpolar space of which a magnetic rotor 3 is located. The stator magnetic wire 1, 4 contains three independent working windings 2, which create a single electromagnet that is switched on to sector 240" or 120".

To expand the possibilities of connecting a tripolar motor-generator in the combined mode of production of both mechanical and electrical energy, additional

From the stator 5 (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. Operation of the 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. With, a. Three sections of the excitation winding with inductance | are connected in series and form a single electromagnetic system. The process of induction and self-induction of each section of HER 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 magnetic 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. 3, 6. Unlike the scheme of fig. With, and, on top of each section of it, the winding of the wire I wire is wound, designed to divert the electrical energy applied to it to the external load. In order to exclude the mutual influence of the coils of the connection Yzv 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 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 electric motor mode when external electricity is supplied to the contacts and (Fig. 3) and the electric generator mode, in which electricity is removed from the stator windings. not involved in the implementation of the motor mode.

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 60 of the tripolar disk motor-generator.

Example 2. As one of the examples of the use of a tripolar disk motor-generator, 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.
