Why Planetary Gear set is really amazing?

This is a planetary gear set, or you can call it an epicyclic gear.
It is used in reduction gear box and automatic transmission.
In a single stage planetary gear set, there is sun gear in centre , sun gear is powered by input shaft, multiple planet gears are installed on the carrier.
besides rotating itself ,these planet gears can orbit around the sun gear when ring gear is locked. Thus carrier rotates and transmits power to the output shaft.
The biggest advantage of planetary gear set is that input and output shaft remains in coaxial form by its design and both shaft rotates at same direction. but output shaft rotates at much slower speed while delivering huge torque output .
Lets find the gear ratio of different gear set.

Assuming both planetary sets have the same ratio, (3.33:1) You MULTIPLY the reduction of both gear sets. The answer is A. (~11.1:1 final ratio)

Gear mechanics is increadably facinating to me. The different types of gear boxes and infinate number of combinations is mind boggling and awesome. A mechanical science on it's own.

quite amazing - and nicely explained. i come from an electronics background, and dont know much about gears and mechanics. in electronics - you have a transformer - which takes a certain voltage (120volts) and reduces it to another voltage (5volts) - it entails a power reduction - but how is this done mechanically!? when one thing is turning faster than another!? how do you make the faster thing turn the speed of the slower thing (imparting greater power and torque)!? 🍃 the ingenious PLANETARY GEAR is really amazing - a mechanical transformer! thank you for your excellent explication! the animation is superbe, the explanation itself is clear, and the voice is clear, and one of the more pleasant sounding english robot voices ive heard (you can tell where it lacks plural inflections).

@Jacopski

All the videos I watched on this subject either assumed the carrier or ring gear to be stationary and don't explain how either or could be the case and how it can be reduced further, great vid

Looks perfect for starting a Axial Flux generator and motor combo...

@omi-gear

Is torque double at the center of planet gear or circle of gear, or center of driven shaft... How we calculate.?

11.1 is it?

Can you give me an example of application where the sun gear is fixed ring is output

I understand that as the 30 teeth sun gear rotates, planet gear transfers this 30 teeth among the 70 teeth of ring gear causing 154.285 degrees rotation of the carrier. But why this turn causes additonal turn at sun gear? (video time
