How do the torque motors know when to erect themselves? This question was asked in my instrument class for extra credit and I can't find it...

My question is...
How does the gyro detect that it is not erect (during flight) and erect itself. For example a vacuum driven gyro has pendulous vanes that open and close... Electrical gyros have torque motors, but how do they know when to erect. The vacuum driven ones are done by gravity force to swing the pendulous vanes to cover the exhaust valves to create an uneven force to cause the gyro to erect...make sense?Tanner Johnson - Owner

I'm not necessarily talking about the planes I'm flying, it was a question posed by my instrument theory instructor. It's weird and kind of hard to understand.
Like I said above with the vacuum driven gyro it has the pendulous vanes. Electrical gyros have two torque motors, but how do those motors know the gyro needs to stay erected. That's how he put it to me tonight in class when I asked about it.
I read where there is a magnet on top of the gyro and then a like track around it with bearings. Once it turns the balls on the track fall making the gyro erect...is this correct?Tanner Johnson - Owner

Maybe, I don't know. Your question is more about gyroscopes than it is about airplanes. As I said, when the gyro gets turned on it erects and stays in the same place and the plane moves around it. If your question is the specifics of how the gyro itself does that, then you should look up technical details of how gyros work and you'll find your answer.

Gyros are quite a big part of airplanes... I have searched online and the reason I am asking is because I figured someone who has been taught how the gyros work would maybe be able to answer. Especially people flying the jets that use electronic gyros rather than Vacuum driven airplanes, especially since I'm sure in their systems training probably taught them. I guess I'm going to have to go the the EMB-145 manual and look it up.Tanner Johnson - Owner

But you are still taught that as a part of systems training. You obviously don't know the answer so stop replying and maybe someone else will answer. I knew how a vacuum gyro worked so obviously someone who flies with an electric one and goes through decent flight training (141 or airline) would know and can answer this. He'll maybe a mechanic might be here.Tanner Johnson - Owner

Do you have to be such a prick to everyone?
Honestly, go look it up in your book, Im sick of you being so lazy when you having something that will tell you but come here and ask instead!

1st.
Most commercial aircraft produced in the last 10 years do not use mechanical gyros. The solid state "Ring Laser" gyro is used.
2nd.
The electric mechanical gyro erects in exactly the same principles as the vacuum gyro. It senses gravity in the same way and signals the torque motors using transducers instead of vanes.Don
