Definitions

  • the invention is related to electrical machinery and generators.
  • Rotational thermal generator of the proposed design converts mechanical rotational motion into thermal energy.
  • the installation operates on the basis of induced currents generated by changing magnetic field. Electric currents induced by changing magnetic field are also referred to as 'Foucault currents'.
  • Magnets are fixed to a moving unit - a rotor that rotates by virtue of an axis with bearings. Magnetic field generated by permanent magnets is closed by a ferromagnetic stator. The motion induces currents in the ferromagnetic stator. The induced currents heat the stator. Thus, the energy of mechanical rotation motion is converted into thermal energy.
  • Stator can be homogeneous or constructed using several metals, such as copper and steel, aluminium and steel, or other structural compound of low resistance metals with ferromagnetic materials. As the stator is heated, it transfers the heat to a heat exchanger made of fins and attached to the stator. Heated stator and heat exchanger emit heat into the surrounding medium, thus transferring it into air or other gas.

  • the advantage of the proposed design is simple production not requiring any special materials or special manufacturing equipment.
  • Thickness of the outer steel element of the rotor shall ensure that magnetic field is closed by magnets without forming additional magnetic resistance.
  • the rotor can rotate.
  • stator As the rotor rotates during operation, currents are induced in the stator. Given that each material has its specific electrical resistance, the material becomes heated by the running current. The running induced currents heat the stator. The stator transfers the heat to the surrounding medium.
  • Operating conditions of the generator are determined by efficiency of the coolant and circulation.
  • Output of the generator is determined by permissible operating temperature of the magnets, strength of the magnets, number of the magnets, rotational speed of the rotor, and coercive magnetic field formed by the running induced currents.

Abstract

La présente invention concerne un générateur thermique rotatif qui convertit un mouvement rotatif mécanique en énergie thermique. L'installation fonctionne sur la base de courants induits générés par le changement de champ magnétique. Les courants électriques induits par le changement de champ magnétique sont également appelés « courants de Foucault ». Des aimants sont fixés sur une unité de déplacement - un rotor qui tourne grâce à un axe doté de paliers. Le champ magnétique généré par les aimants permanents est fermé par un stator ferromagnétique. Le mouvement induit des courants dans le stator ferromagnétique. Les courants induits chauffent le stator. Ainsi, l'énergie du mouvement de rotation mécanique est converti en énergie thermique. Le stator peut être homogène ou construit au moyen de plusieurs métaux, tels que le cuivre et l'acier, l'aluminium et l'acier, ou un autre composé structural de métaux de faible résistance présentant des matières ferromagnétiques. Lorsque le stator est chauffé, il transfère la chaleur à un échangeur thermique composé d'ailettes et fixé au stator. Le stator chauffé et l'échangeur thermique émettent de la chaleur dans le milieu environnant, la transférant ainsi dans l'air ou dans un autre gaz.
