| Don't understand why all companies using pinion to drive the generator

| It is not companies but individuals who found it the most appropriate place to put the generator ! If you put it on any other place then you do not have charging while heli is on idle or during auto rotation !

I take it you mean the configuration where the generator is driven by the main gear through a pinion.
To be fair, in this configuration there is no charging at idle either, since in this condition the clutch will still be disengaged and the main gear won't be spinning yet.
Driving the generator from the starter shaft is IMO actually better because it won't add drag to the main gear (and rotor) during autorotation, so it won't affect your heli's autorotation performance. And, your battery won't have trouble powering the radio for the few seconds' worth of auto (people do fly even without a generator after all).
Of course there are cases where it is impossible to drive the generator from the starter shaft and I'd then rather drive it from the main gear, with or without autorotation performance hit, than not having the generator!
