gearbox

Since the gearbox is at the top of the turbine tower it also makes construction and maintenance more difficult.

The tradeoff is a larger propeller and more expensive engine installation due to the required gearbox.

Many turbines spend time with their blades locked because the wind is too strong - they would turn too fast for their gearbox to handle.

Why they include an animated gif of someone turning another gearbox with a far lower ratio puzzles me.

So in essence a electric engine could benefit from a gearbox for the inverse of a gas engine.

So it looks like VW was rather thoughtful to introduce this delay, when there is a manual gearbox.

That has always been easy to do and is the sort of thing this compact gearbox avoids.

This also decreases the loading on the drive system and permits a smaller gearbox ratio, which helps to improve efficiency.

To match this variable but low speed system to the generator you need a gearbox.

It would not surprise me if the electric carts have a minimal at best gearbox between the engine and the wheels.

You need a sensor in the gearbox itself to know if you are in gear.

The gearbox concatenates two such transmissions, therefore, it cannot be operated backwards.

Maybe make the gearbox out of mirrors and the "shaft" out of light.

What you are describing is called "backdriving" the gearbox.

I found a test plan for this on the old 5 series [1] BMW say the engine should return to idle speed "immediately." The wiring diagrams imply that for this car, the electronic throttle was only applied to cars with automatic gearboxes and traction controls, the benefit here being that the electronic throttle can act to limit engine power during gearbox shifting or during intervention of the traction control.
