Help with rotation?

[Andrew Blair]

I have completed my model of a speed controller, and am now attempting to make the fan nicely come up to speed and spin. However, I can't seem to figure out how to do it. I've tried using reactor stuff, but it doesn't work. I'm sure there is a relly simple way to do it using animation constraints, but I need some help to find out how to do it! Any ideas are appreciated! :)

Look into using the Curve Graph.

And under your rotation, and set a nice curve.

Thanks, works like a charm! I really need to work on that curve editor.......
