Animation of rotating shaft

Animation of rotating shaft

Animation of rotating shaft

(OP)
Hi all,

Has anyone had any success with rotating a shaft in an assembly for a specific number of complete rotations, say three?   

I'm working on a large animation and have been able to "eyeball" when to get shaft to stop on the third complete rotation watching the edge of the keyway but unfortunately, there is a lag between when I press the "stop recording" button and when the program catches up to that input.  This leads to an unsightly bounce back when looping the animation.

A single revolution would be fine normally, except that more revolutions seems to give a better rotational speed for the rest of what I'm trying to do with the animation.

The numeric function of the rotary motor is great for speed control, and I've had little luck with an angle limit mate as it stops at a max of 360 degrees.  

Any ideas are very much appreciated...

RE: Animation of rotating shaft

Are you using 2006?

If so, I'd recommend rotating your shaft with the 360* limit mate you mentioned.  Then simply copy that operation three times within equal time-frame spaces.  You'll have three rotations, which should appear as seamless, using that method.

The limit mate will help in keeping the motion consistent/accurate through the rotation cycles.
