  • the invention relates to electrical engineering and can be used in transmissions where a smooth change in the gear ratio is required.
  • the disadvantages of the known variator are increased energy losses due to the need to convert all mechanical energy into electrical and reverse conversion of all electrical energy to mechanical, as well as the need to use brush assemblies when transferring electricity from movable variator components to stationary ones and vice versa.
  • the technical result is an increase in efficiency due to a decrease in the value of double conversion of energy, as well as elimination of losses during the removal of electricity from the machine and during its return supply due to the arrangement of the armatures of both machines in one common rotating unit, in which the inverters of these electrical machines are also located.
  • the electromagnetic variator contains at least two electrical machines installed in the housing, input and output shafts located coaxially, while a rotating rotor of the first machine is installed on the input shaft, which interacts with the armature of the first machine, which is mounted on the output shaft of the variator, the armature of the second machine is also installed on the output shaft, and its windings are electrically connected to the armature windings of the first machine to form a single rotating inductor unit, and not the rotating rotor of the second machine, interacting with the armature of the second machine, is connected to the variator case, each the machine is equipped with an inverter.
  • the task is also achieved by the fact that the rotor of the second machine can be installed with the possibility of controlled translational movement along the axis of rotation of the armature.
  • the task is also achieved by the fact that the rotor of the second machine can interact with the body through a freewheel clutch with the ability to rotate around the axis of rotation of the armature in one direction.
  • the variator can contain at least one additional electric machine, the armature of which is mounted on the output shaft, and not the rotating rotor is connected to the variator housing.
  • the rotor of the additional electrical machine can be connected to the output shaft by means of a mechanical gearbox.

  • FIG. 2 is a diagram of a variator with an additional electrical machine.
  • the variator contains an input shaft 1 installed in the supports of the housing 2, on which a rotating rotor 3 of the first electric machine is installed, interacting with the windings 4 of the armature 5 of the first machine, which is located on the output shaft 6 of the variator.
  • Permanent magnets 7 are installed on the rotor 3, and the shaft 6 is located coaxially with the input shaft 1.
  • the output shaft 6 also houses the armature 8 of the second electric machine, the windings 9 of which are electrically connected to the windings 4 of the armature 5 of the first machine through the inverter 12 of the first electric machine and the inverter 13 the second electrical machine and form a single rotating inductor unit with them.

  • the input shaft 1 drives the rotor 3 with permanent magnets 7 installed on it, which induces the EMF in the windings 4 of the armature 5.
  • the input moment applied to the input shaft and the rotor of the first electric machine connected to it is transmitted through the armature 5 to the output shaft 6 connected to it.
  • All the electrical energy generated by the first electric machine is converted through the inverter 12 into a constant voltage, which is fed through the buses 14 through the inverter 13 to the second an electric machine, the rotor 10 of which is connected to the case 2 of the variator.
  • the moment of the second electrical machine is also applied to the output shaft 6, since the armature 8 of the second electrical machine is also rigidly connected to the output shaft 6.
  • the operating speed of the first electrical machine determines the difference in rotation of the input and output shafts. Accordingly, at a constant input torque, the first electric machine generates a different amount of electrical power. With a large difference, more electrical energy is generated, respectively, the output torque increases, since all the electrical energy generated by the first machine is supplied to the second electric machine, the entire torque of which is also applied to the output shaft 6. With a small difference in the revolutions of the input 1 and output 6 shafts (small gear ratio of the variator) on the first electric machine, less electric power is generated and, accordingly, less torque added to the output shaft 6 by the second electric machine. As a result, as the variator gear ratio increases, the output torque increases. With a decrease in the gear ratio, the torque decreases, while the overall efficiency of the variator increases, since the share of energy that passes through the variator without double energy conversion (mechanical electrical - mechanical) increases.
  • Electric machines as part of a variator can be of a synchronous or asynchronous principle of operation.
  • the described variator is capable of operating both in the direction of energy transfer from the input shaft to the output shaft, and in the opposite direction - to the input shaft.
  • the second machine is in generator mode and the first in engine mode.
  • the use of the claimed variator allows increasing the efficiency of the system due to a large proportion of directly transmitted mechanical energy without converting it from mechanical to electrical, and vice versa. All the power electrical components of the variator are located in one rotating block, and the high currents of the power modules will not escape from it. At the same time, losses are prevented during the transfer of electrical energy from one machine to an external control system and return of this energy to another machine through high-current brush units.

Abstract

L'invention se rapporte au domaine de l'électrotechnique et peut être utilisée dans des transmissions où il est nécessaire d'assurer un changement en douceur du rapport de transmission. Le résultat technique consiste en une augmentation du coefficient d'efficacité grâce à une diminution de la valeur de conversion double de l'énergie, ainsi qu'à l'élimination des pertes lors de la sortie d'énergie électrique depuis une machine et lors de son renvoi du fait de la combinaison des induits de deux machines en une unité rotative unique dans laquelle sont également disposés des onduleurs de ces machines électriques. L'invention concerne essentiellement un variateur électromagnétique comprenant au moins deux machines électriques disposées dans un corps, et des arbres d'entrée et de sortie disposés coaxialement. Sur l'arbre d'entrée se trouve un rotor rotatif de la première machine entrant en interaction avec l'induit de la première machine qui est disposé sur l'arbre de sortie du variateur; l'induit de la seconde machine est également disposé sur l'arbre de sortie, et ses enroulements sont connectés électriquement aux enroulements de l'induit de la première machine de manière à former un bloc à induction rotatif unique. Le rotor non rotatif de la seconde machine entrant en interaction avec l'induit de la seconde machine est connecté au corps du variateur, et chaque machine comprend un onduleur.
