Ecco
Working out planetary gear turns ratios
Tr Turns of the ring gear
Ts Turns of the sun gear
Ty Turns of the planetary gear carrier
R Ring gear teeth
S Sun gear teeth
P Planet gear teeth
The turns ratio is as follows:
( R + S ) ×Ty = R × Tr + Ts × S
For my setup the gear ratio turns out to be approximately 1.5:1, or 1.5 rotations of the wheel will result in 1 rotation of the magnet.
So, for 20 mph bikes this will go to -> ~30 mph (a little less since you can't quite get to 20 mph in the first place)
For 25 kph bikes this would go to -> ~37.5 kph
Mi lascia perplesso quel "approssimativamente"
Non so se sia necessario fare qualche tipo di test, eventualmente mi rendo disponibile
