Abstract
The present invention refers to 'Differential Integral Electrical Machine', whose reliability, technology for manufacture and price is comparable with the conventional induction machines. The differential integral generator is generating electrical tension whose frequency does not depend on the revolutions of the rotor. This is a generator at which the values of the generated tension, of the active and reactive power can be adjusted by changing the turns of the primary engine or by changing the excitation and the synchronization, concerning the frequency, can be done at the moment in which is applied tension from the mains to the exiting system of the generator. The alternating current differential integral motor is a machine at which the speed of rotation of the rotor does not depend on the frequency of the mains and can be smoothly regulated only by changing the value of the impressed tension. This is a motor with adjustable power factor, inductive, equal to one or capacitive. The direct current differential integral motor is an electrical machine at which the armature winding is mounted on the stator and is connected directly to the grid and the inductor is on the rotor. The differential integral electrical machine appears as an alternative of the conventional electrical machines.
Description
DIFFERENTIAL INTEGRAL ELECTRICAL MACHINE
This invention relates to Differential Integral Electrical Machine and especially to - 1. Alternating current generator, single-phase and multi-phase, generat¬ ing electrical tension, which value depends on the speed of rotation of the "Differential Integral Inductor", with frequency of the generated tension independent from the speed of rotation of the inductor, with adjustable power factor - inductive, equal to one or capacitive; 2. Alternating current motor, single-phase and multi-phase, with smoothly adjustable speed of rotation of the rotor [inductor] only by changing the value of the impressed tension, with adjustable power factor - inductive, equal to one or capacitive; 3. Direct current electric motor with armature winding mounted on the stator and connected directly to the supplying grid, i.e. without use of any commutating devices - which can find application into electrical machinery construction.
Heretofore, the known electrical machines - induc¬ tion [asynchronous], synchronous a.c. and direct current machines, which we'll call conventional, are built up on three different principles. Each of these principles pre¬ determines the quality of the relevant machines. At the present moment the all three principles theoretically and practically are exhausted. New development can be ex¬ pected only for machines built up on new physical princi- pies. The use of the power electronic helped for removing of a lot of the substantial defects of the conventional machines, but in the more cases this is connected with high additional expenses
The defects of the synchronous machines are deter- mined by the inductor placed on the rotor, inductor pro-
viding magnetic field which rotates in the space in syn¬ chronism with the field provided by the armature winding and as a result at the synchronous generators exist: Dependency of the generated frequency on the speed of ro- tation of the inductor, but this puts higher requirements to the primary engines and their regulators and as a fi¬ nal result is reduced the circle of the suitable for pro¬ duction of electrical energy primary engines; For switch¬ ing on in parallel at precise synchronization is neces- sary long time, but this is unacceptable especially at emergency situations; At rough synchronization switching on in parallel is related with big overcurrents. The re¬ covery of the synchronism in the electrical systems is labour consuming process and can cause big losses. The defects of the synchronous motors are: Absence of own starting torque; At asynchronous start - small starting torque and big starting current; Smooth adjustment of the speed of rotation can be achieved only by change of the frequency of the supplying tension. The defects of the induction [asynchronous] ma¬ chines are determined by the lack of isolated inductor. The located on the stator armature winding serves as ex¬ iting winding too, creating rotating into the space mag¬ netic field. This field determines the rotor field which rotates in synchronism with the main magnetic field. At turnovers of the rotor higher than the synchronous turnovers the machine changes into generator, consuming from the system inductive energy, but this is unaccept¬ able, because requires the use of additional equipment for compensation in the system. At turnovers of the rotor lower than the synchronous the machine changes into a mo¬ tor having the following defects: The squirel-cage induc¬ tion motor has a small starting torque, big starting cur¬ rent, quadratic dependence of the torque from the sup- plying tension, for smooth adjustment of the speed of
rotation is necessary supplying equipment permitting smooth change of the frequency; The induction slip-ring motors require additional devices such as slip-rings, brushes, resistors. On practice, these devices are used only for improvement of the starting characteristics of the motor; The induction motors are working with rela¬ tively low power factor and this requires the use of equipment for compensation.
The defects of the direct current motors are prede- termined by the located on the stator inductor consuming 2 - 5 % from the total energy used by the machine, but the most loaded part - the armature winding accepting to 95 % from the consumed energy is located on the rotor and is connected to the grid by means of commutator and brushes. The presence of a commutator and brushes to¬ gether with the disposition of the armature winding on the rotor is limiting the use of these machines only in the range of the low tensions and powers. Because of the listed reasons the access to the armature winding is im- possible and the adjustment of the speed of rotation can be done only by using outer resistors; The big currents in the armature winding stipulate all unfavorable conse¬ quences related with the commutation.
The listed above constructive properties and de- fects of the conventional electrical machines are de¬ scribed in details in books No. 2 to 5 pointed out in the bibliographical inquiry.
The task of the invention is to be created electri¬ cal machine, designed for conversion of the mechanical energy into alternating current single-phase and multi¬ phase electrical energy and for conversion of direct cur¬ rent, single-phase and multi-phase alternating current energy into mechanical energy, suitable for all powers and tensions, and to be removed the above pointed out ba- sic defects of the conventional machines, and this means:

To be created direct current motor at which the armature winding is mounted on the stator and is connected directly to the supplying grid, i.e. removed are all commutating devices in the armature winding cir¬ cuit; Motor at which the exiting winding is placed on the rotor and is connected to the supplying grid by means of mechanical or other type commutator, but because of the small currents flowing in the independent one from an¬ other sections of the exiting winding, the problems re¬ lated with the commutation are overcomed. 4. To be cre¬ ated such electrical machine at which the windings to be independent one from another in such degree, that they permit different schemes of connection, and by this way to be ensured the necessary characteristics, suitable for the different operated machinery. 5. To be created elec¬ trical machine which can be executed as bipolar, multipo- lar, single-phase and multi-phase, suitable for all pow¬ ers and tensions.
The task is solved by an electrical machine com¬ prising stator, rotor-inductor, windings. According to the present invention the machine consists of two basic parts "Differential part" and "Integral part", and each of them includes part of the stator and part of the rotor and this arrangement is in force at the bipolar and mul- tipolar direct current machine and at bipolar, multipo- lar, single-phase and multi-phase alternating current ma- chine and comprises of: Stator, which represents hollow body in which are incorporated the differential and the integral stator magnetic cores having cylindrical inter¬ nal surfaces, as in the interior of the stator magnetic cores is placed the differential-integral inductor, which is the rotor of the machine, laid on bearings mounted on
supports providing coaxiallity between the inductor and the stator magnetic cores.

Differential winding, placed in the evenly distributed slots of the differen¬ tial rotor magnetic core, made up of multiple-turn sec¬ tions electrically insulated between them and towards the magnetic core, as the ends of each section are connected only with the ends of the laying in the same plane sec¬ tion of the integral winding, as the pitch of these sec¬ tions is limited into the framework of the pole division. Integral winding, placed in the evenly distributed slots of the integral rotor magnetic core, made up of multiple- turn sections electrically insulated between them and to¬ wards the magnetic core, as the ends of each section are connected only with the ends of laying in the same plane section of the differential winding, as the pitch of these sections is limited into the framework of the pole division.

Referring now to the drawings the machine consists of a stator, rotor-inductor, windings, united in two ba- sic parts "Differential" and "Integral" as each of them includes part of the stator and part of the rotor and comprises of: Stator 1 which represents a hollow body in which are incorporated the differential 2 and the inte¬ gral 3 stator magnetic cores having cylindrical internal surfaces, as in the interior of the stator magnetic cores 2 and 3 is placed the differential-integral inductor, which is the rotor of the machine, laid on the bearings 4 mounted on supports 5 providing coaxiallity between the inductor and the stator magnetic cores 2 and 3. Differential-integral inductor consisting of a common
shaft 6 .on which are mounted the differential 7 and the integral 8 rotor magnetic cores having cylindrical exter¬ nal surfaces. Exiting winding 9 placed on the differen¬ tial stator magnetic core 2, made up by concentrated coils forming bipolar, three-polar or multi-polar with number of the poles divisible by two, by three, or by two and three simultaneously, single-phase or multi-phase ex¬ iting system as the location of the poles determines the zones in the integral part of the machine in which are placed down the face conductors of the armature winding 12, as for a part of in series connected turns for each phase of the exiting winding 9 are made up leads-out con¬ nected to the terminals of the machine. Differential winding 10 placed in the evenly distributed slots of the differential rotor magnetic core 7, made up of multiple- turn sections electrically insulated between them and to¬ wards the magnetic core 7, as the ends of each section are connected only with the ends of the laying in the same plane section of the integral winding 11, as the pitch of these sections is limited into the framework of the pole division. Integral winding 11 placed in the evenly distributed slots of the rotor magnetic core 8 made up of multiple-turn sections electrically insulated between them and towards the magnetic core 8, as the ends of each section are connected only with the ends of the laying in the same plane section of the differential winding 10, as the pitch of these sections is limited into the framework of the pole division. Armature winding 12 located in concentric towards the axis of the machine, coordinated with the poles of the exiting system, and evenly distributed slots of the integral stator magnetic core 3, made up as a totality of connected in series turns for which the sum of the embraced of each turn parts of the main magnetic flux is equal to zero, the turns of which are united in sections connected in series

Compensating winding, placed into the slots of the integral stator magnetic core 3, or mounted on the commutating poles lo- cated between the zones with face conductors of the arma¬ ture winding 12. Devices for cooling, fan 13, for con¬ necting to the electric grid, for mounting and transport. According to the present invention the task is solved also by differential 10 and integral 11 windings united in a common squirel-cage winding made up with dif¬ ferential and integral sections performing 1/2 turns con¬ sisting of placed in the slots of the rotor magnetic cores 7 and 8 and insulated from them conductors which ends are. connected to the common short-circuiting rings located on the outer plane sides of the rotor magnetic cores 7 and 8.
According to the present invention the task is solved also with a differential part of the machine sub¬ stituted by contact device consisting of insulated be- tween them contact lamellas 14 placed on the cylindrical surface of an insulating cylinder 15 mounted on the shaft 6 of the rotor, as the number of the lamellas 14 is equal to the number of the connected to them ends of the insu¬ lated between them sections of the integral winding 11 and brushes 16 located in the planes dividing the inter- pole spaces, as their number corresponds to the number of the poles of the exiting system from the differential part of the machine.
According to the present invention the task is solved by an exiting winding 8 or connected to a contact
device an integral winding 11 and an armature winding 12 connected in series, in parallel, compound or indepen¬ dently towards the supplying grid.
The machine is working in the following way. At impressing alternating single-phase or multi¬ phase tension to the exiting winding 9 in the differen¬ tial part of the machine will be formed alternating in the time and stationary in the space exiting magnetic flux, whose distribution is determined by the number of the poles and the number of the phases of the exiting system. As well as at rest, and so at rotating movement of the differential-integral inductor in the turns, re¬ spectively in the sections of the differential winding 10, the exiting magnetic flux will induce electromotive forces [tensions] . In this sense the differential part of the machine can be considered as transformer with primary winding, the exiting winding 9 and secondary winding, the differential winding 10 consisting of electrically insu¬ lated between them sections, which at their rotating movement are differentiating the energy of the electro¬ magnetic wave formed by the exiting system and in the form of electrical tensions and currents the differenti¬ ated energy of the exiting system is transmitted to the integral winding 11 of the differential-integral inductor in the integral part of the machine. The same process goes and in case, when the differential winding 10 is a part of the common differential-integral squirel-cage winding. At the contactor machines, at which the differ¬ ential part is substituted by a contact device, the sup- plying direct current or alternating current exiting ten¬ sion is impressed by the brushes 16 and the received en¬ ergy is differentiated into portions by means of the con¬ tact lamellas 14 to which are connected the ends of the sections of the integral winding 11 which rotates to- gether with the rotor.
The integral winding 11 summarizes [integrates] the portions of the electromagnetic energy received in the form of tensions and currents in its sections and forms the main magnetic flux which represents an integral mag- netic flux. As well as at stationary, so at rotating in¬ ductor the main magnetic flux is formed by one and the same number of sections of the integral winding 11. The main magnetic flux can be formed as a bipolar, multi-po¬ lar, single-phase or multi-phase magnetic system, as a constant or alternating in the time magnetic field, but it always is stationary in the space nevermind, that the inductor is at rest or is doing rotation movement at a condition, that the exiting system or the- brushes are mo¬ tionless. The main magnetic flux can rotates in the space in case, that the exiting system together with the stator 1 or the brushes 16 together with stator 1 are rotating, but the inductor remains motionless. In all cases the main magnetic flux is distributed and disposed in the zones of the integral stator magnetic core 3 in accor- dance with the polar and the phase distribution, deter¬ mined by the poles and phases of the exiting system, or in the zones, determined by the number and the location of the brushes at the contactor machines, as in the same zones are placed the face conductors of the armature winding 12. The existence of the main magnetic flux is necessary condition for realization of the two basic op¬ erating regimes of the differential-integral electrical machine, as a generator and as a motor.
At availability of an alternating in the time main magnetic flux in regime of generating, the differential- integral inductor is set into rotating motion by means of primary engine, at what in the armature winding 12 is in¬ duced alternating electric tension, the frequency and the form of the wave of which corresponds to the frequency and the form of the supplying tension impressed to the
exiting winding 9 or to the brushes 16 of the contactor and with value of the induced in the armature winding 12 tension, determined most commonly as a function of the value and the frequency of the main magnetic flux, the active length of the armature winding 12 and the fre¬ quency [the speed] of rotating of the inductor. As well as by changing the frequency of rotation of the differen¬ tial-integral inductor, so by changing the value of the main magnetic flux or by simultaneously changing of these two parameters can be adjusted the values of the gener¬ ated active and reactive power, so can be choosed the op¬ timum variant ensuring the needs of active power and in¬ dependently of it the needs of reactive inductive or ca¬ pacitive- power. The differential-integral generator doesn't form own frequency of the generated tension and because of this reason it becomes synchronized automati¬ cally with any source supplying the exiting system of the machine, or which provides tension applied to the brushes 16 at the contactor machine. The independence of the gen- erated frequency from the revolutions of the differen¬ tial-integral inductor is making practically unlimited the possibilities for choice of the primary engines, which can be low-speed, high-speed, or with variable in wide limits speed of rotation. At constant in the time main magnetic flux the dif¬ ferential-integral generator is generating alternating tension, whose frequency is determined by the electromag¬ netic and constructive parameters of the machine.
At" availability of alternating in the time main magnetic flux and impressing alternating tension with the same frequency and phase, as the frequency and the phase of the main magnetic flux, to the armature winding 12, or at availability of a constant main magnetic flux and im¬ plying direct current tension to the armature winding 12, is created a moment of motion and as a result the rotor
of the machine is set into continuous motion. By varia¬ tion of the impressed to the armature winding 12 tension, by changing the number of the connected in series turns of the armature winding 12, by changing the value of the main magnetic flux, or by simultaneous changing of some of these parameters can be adjusted the value of the cre¬ ated moment of motion, which is highest at resting induc¬ tor, and the number of revolutions of the rotor. At the alternating current differential-integral motors the num- ber of the rotor revolutions doesn't depend on the fre¬ quency of the supplying tension impressed to the armature winding 12, to the exiting winding 9, or to the brushes 16 at the contactor machine. By changing the value of supplying tension impressed to the exiting winding 9 or to the integral winding 11 at the contactor machine, re¬ spectively by changing the value of the main magnetic flux, can be adjusted the power factor of the machine, which can be chosen inductive, equal to one or capaci¬ tive. By suitable dimensioning and selection of the dia- gram for connection of the armature winding 12 and the exiting winding 9, or of the armature winding 12 and the integral winding 11 at the contactor machine can be cho¬ sen the most proper working characteristics of the motor. For compensation of the armature current reaction is used compensating winding connected in series to the armature winding.
For cooling of the machine is used the fan 13. For connecting to the electrical grid, for mounting and transport are used standard devices.
