  • Known magnetic rotor system consisting of a package of disco-shaped plates with radial rectangular grooves with different placed in them by tangential permanent magnets, which is equipped with bursts of wedge-shaped plates, placed along the axis in alternating order with disk-shaped plates to reduce the dispersion flux (see a.s.

  • This magnetic system despite the decrease in the dispersion flux, has a low value of the working magnetic flux, which is due to the small radial dimensions of the magnets, limited by the radial dimension of the rotor.

  • This magnetic system in comparison with the above-described designs, allows, due to the inclined installation of magnets, either to increase the radial size of the magnets for a given radial dimension of the rotor, and therefore to increase the value of the working magnetic flux, or, while maintaining the working magnetic flux, to reduce the radial dimensions of the rotor.

  • the technical result achieved by the implementation of of the inventive invention is to reduce the dispersion flux with an inclined installation of magnets and, as a consequence, to increase the working magnetic flux.
  • the specified technical result by the claimed invention is achieved due to the fact that in the magnetic system of the rotor, consisting of a package of plates of magnetically conductive steel with holes and permanent magnets of a prismatic shape with tangential magnetization NS, installed in the holes of the plates at an angle to the radial axis so that the distance between different the nominal poles of two adjacent magnets along the outer arc are smaller than the inner, the holes are made V-shaped, and the magnets installed in them forming the pole division e, touch the poles of the same name.

Due to the fact that the magnets Those who are involved in pole division are in contact with the poles of the same name, the scattering fluxes decrease, and the working magnetic flux increases. An additional decrease in dispersion fluxes is achieved by installing non-magnetic inserts under the magnets forming the pole division, which significantly increases the energy performance of the magnetoelectric machine.

Abstract

L'invention appartient au domaine des équipements électriques et concerne notamment la réalisation technique de systèmes magnétiques des rotors de machines magnétoélectriques sans collecteurs, et peut s'utiliser dans des moteurs ou des génératrices. Le système magnétique de rotor est constitué d'un paquet de plaques d'un acier conducteur d'ondes magnétiques comportant des orifices en V, et d'aimants permanents en forme de prisme ayant une charge magnétique tangentielle N-S. Les aimants formant une séparation de pôles sont montés dans les orifices des plaques avec une inclinaison par rapport à l'axe radial et sont en contact par leurs pôles ayant le même signe. Sous les aimants formant la même séparation des pôles on peut installer des inserts non magnétiques. L'invention permet de réduire les flux de dispersion avec une inclinaison inclinée des aimants et, par conséquent, d'augmenter le flux magnétique utile tout en respectant les dimensions radiales du moteur.
