The utility model discloses realize the principle

The following description of the operating principle when the shaft of the field rotor is used as the kinetic energy input and the shaft of the armature rotor is used as the kinetic energy output:

kinetic energy is input from a kinetic energy input end to drive the magnetic field rotor to rotate so as to form a rotating magnetic field; at the moment, magnetic lines of force of the rotating magnetic field cut coils of the rotating body of the armature rotor, induced electromotive force is generated on the coils of the rotating body of the armature rotor, when the coils of the rotating body of the armature rotor are closed, current is generated in the coils (when the coils are connected with a load, the coils are in a closed state), and the electric energy input and output end is connected to the coils of the rotating body of the armature rotor; when an infinite rotation resistance is arranged on the kinetic energy output end, the kinetic energy output end cannot rotate, namely the armature rotor cannot rotate, and the kinetic energy output end is equivalent to a stator, and the working principle is the same as the generator principle; when the armature rotor and the magnetic field rotor generate power by cutting magnetic lines, a force (called as a magnetic force in the rest of the text) is generated on the armature rotor, and the force depends on the current on the coil of the rotating body of the armature rotor; the magnetic force can be understood as friction force (more easily understood according to friction force), such as automobile clutch pressure plate and automobile clutch plate, the kinetic energy transmission of the automobile clutch is to change the pressure between the clutch pressure plate and the clutch plate to adjust the friction force between the clutch pressure plate and the clutch plate, when the friction force between two objects is larger, the slip between the two objects is smaller, otherwise, the friction force between the two objects is smaller, the slip between the two objects is larger, the magnetic force between the two objects is changed by changing the current of the electric energy input and output end, the larger the current is, the larger the magnetic force is, the smaller the current is, the smaller the magnetic force is, the larger the slip between the two objects is, therefore, the slip of the kinetic energy input end and the kinetic energy output end is changed by adjusting the current of the electric energy input end and the electric energy output end, the speed is adjusted, and meanwhile, the power generation is carried out, and the slip rotating speed between the kinetic energy input end and the kinetic energy output end is the rotating speed for actually generating magnetic line cutting.
