  • the stator is fixed, and the rotor rotates inside the stator under the driving of the power driving mechanism, or the so-called “rotor” is fixed and the “stator” rotates.

  • the technical problem to be solved by the present invention is to overcome the conventional habit of the stator of the generator being stationary, and to provide a generator in which both the stator and the rotor are rotated, and use natural force to increase the power of a single generator.
  • a generator with a rotor in a stator is characterized in that the stator of the generator is not a fixed structure, but a winding device that can rotate around an axis.
  • the rotor and the stator are all driven by their respective power driving mechanisms.
  • the shaft cores rotate in opposite directions independently of each other.
  • the power driving mechanism is a wind wheel, in which one or an array of wind wheels is connected to a rotor, and the other or an array of wind wheels is connected to a stator, and the rotation direction of the rotor and the stator can be reversed under natural wind driving.
  • the blades of each group of wind wheels may have a two-piece structure, or a structure with three or more pieces.
  • the power driving mechanism is a water wheel, which is provided with two or more groups of impellers. One or an array of impellers is connected to the rotor, and the other or an array of impellers is connected to the stator.
  • the commutation of a commutator (such as a gear) can make the rotor and stator rotate in opposite directions.
  • the generator of the invention is based on two sets of wind wheels or water wheels moving in opposite directions to drive the rotor and stator of the generator, so that the relative rotation speed between the rotor and the stator is greatly increased.

  • the rotating shaft 7 of the rotor (not shown) of the generator 5 is connected to the wind blades 72 and 74 through the swing arms 71 and 73 respectively, because the wind blades 72 and 74 are exactly opposite to the windward side of the wind blades 62 and 64 (see image 3), Therefore, under the impulse of the wind, the rotating shaft 7 will rotate in the counterclockwise direction (as shown by the arrow), thereby driving the rotor to move. Both the stator and the rotor rotate around the axis under the action of force, but the directions are opposite, the relative speed between them is doubled, and the electric power generated will also be greatly improved.

Abstract

L'invention concerne un générateur et un rotor disposé dans un stator. L'invention est caractérisée en ce que le stator du générateur de cette invention n'est pas une structure fixe mais un module d'enroulement qui peut tourner autour de l'axe. Lesdits rotor et stator sont disposés de manière à tourner indépendamment autour du même axe dans un sens opposé. Ils sont entraînés par leur mécanisme électrique respectif.
