There are no motors attached to the thrust levers.
Thanx James7...
Now I finally think I sort of understand the "autothrottle" system on an airbus. You move the thrust levers to CLB and then you can LET GO of them. The autoflight system regulates the required thrust and of course: there is no movement!
So here follows a translation of the various thrust lever settings on an Airbus, written for Boeing drivers (like me-self)
Idle: Hey computer, don't give me any thrust at all, just keep the engine running.
CLB: Hey computer, just give me enough thrust to keep flying and don't bother telling me exactly what you are doing.
TO/GA: Hey computer, give me all you got.
