Permanent magnets

In a conventional machine, the magnetic field needed to produce electricity is generated by winding (copper wire on a metal core). These coils are bulky, complex manufacturing and energy consuming (they are always supplied to create a permanent magnetic field).

To overcome this difficulty, DDIS uses permanent magnets. These permanent magnets give the magnetic field without electrical power: thus, even in case of shortage of power supply, the magnetic flux is always present.
