Inside are several reinforcing elements 5, with the same design, the AC generator 6 with excitation from permanent magnets, the driving shaft 7, one end of which is installed in the bearing of the rear cover of the alternator, and the other is inserted into the end of the driven shaft 8, the free end of which is omitted in the opening of the rear cover of the electromagnetic transmission.

Conclusions from the coils is connected to the input of the rectifying unit 34, the output of which is electrically connected to the brushes electromagnetodynamics linear motor.

Work magnetoelectric transfer.

Before magneto transmission, you need a control knob 11 to disconnect the clutch. While leading the coupling 10 will move to the left and drive shaft 7 is disconnected from the driven shaft 8. When the shaft 28 of the alternator 6 together with him rotate the toothed poles of the magnets 29, lines of force which traverse the windings of the coils 33. As a result, the coils in Snicket alternating current, which arrives at the input to the rectifier unit 34. The rectified DC current is fed to the brushes 17 spectromagnetograph linear motor, and the brush should touch at least four balls 24. The current I passes through the beads in the magnetic field of a C-shaped magnet 15 and the force causing them to move with velocity V (6). As a result, all the balls move through the teeth of the gear 20 rotates the driving shaft 7. If you look at figure 5, which shows the picture of the magnetic field of the magnet 12, we can see that the greatest magnetic intensity is concentrated at the poles, and in the middle part (shown in dashed lines) is missing. Therefore, when the approach of the balls 24 to the top 13 and bottom 14 of the vertical channels they are drawn with acceleration inside the magnet 12 and the magnetic forces and F1and F2. The same balls 24, which are located in the middle of the magnet, will be without any resistance from the magnetic field out of the magnet and move further along the pipes 18, 19. As a result of continuous exposure to a magnetic field of the magnet 12, the speed of movement of the balls 24 will be under the action of the resultant force Fp constantly increased up to a certain point and with it will grow a twisting moment. Other reinforcing members also work. As soon as it is about timing gear 20 and with it the driving shaft 7 has reached its maximum speed and maximum power, turns the control knob 11. Leading the coupling 10 is connected with the driven coupling half 9 and the driven shaft 8 moves and causes the rotation mechanism, which is connected with it. The rotational speed of the driven shaft 8 can be changed by changing the frequency of rotation of the shaft 28 of the alternator and, accordingly, the magnitude of the constant current supplied to the brush electromagnetodynamics linear motor. Driven shaft 8 can rotate in one direction only (figure 7 shown by the arrow). To stop magneto transmission, you need to stop the motor which drives the shaft 28, and a control knob 11 to disconnect the driven shaft 8. Thus during operation of the electromagnetic transmission is additionally used the energy of the magnetic fields of permanent magnets. To power on driven shaft 3 was the maximum, the magnets 12 must have a high magnetic intensity, which is achieved by adding to the composition of the magnets of rare earth elements.

Positive effect: at low cost power input, it is possible to obtain a large output power, the possibility of using low-powered engine to propel a powerful mechanism.
