Motorfader positioning by electrical brake?

[Screaming_Rabbit]

I saw this ad on ebay:

If you have a look at the pictures, it looks like NEVE is solving the precise positioning of their faders by an electrical brake.

The seller of this faders writes, that there is a "Inertia Dynamics" motor in it. But on the website of "Inertia Dynamics" http://www.idicb.com/ you only find brakes and clutches and the appropriate controllers to it - no motors.

Now take another look at the fader module: You see, there are two parts attached to the driver string... seems like an electro motor and a clutch.

... interresting  :o
