Brushless electric generator for helicopter

The generation of electric power in-situ (ie directly on the rotating system through the use of modern electric machines, for example of the type with axial flux with permanent magnets) is performed using an inductor and an element induced magnetically coupled together and having velocity of rotation different (the inductor can also be stationary). The efficiency of the generation grows with the increase in the speed differential, which can be increased through the use of mechanical multipliers.
