That observation seems worthy of a tangential discussion. We haven't used window motors for anything lately, so I can't comment, but I'm very curious. Are there any other teams out there who had a similar (or contradictory) experience using them with Jaguars?

Indeed, in fact there's been a rather interesting discussion about it already, if you're interested. EDIT: Gary's got it.

There is a thread on the Jag and Denso problem.

We have not responded to this thread since removing the locking pins. Even with the locking pins removed, we experienced random Denso shut down. For IRI we swapped out the jags for victors and the problem has disappeared. The window motors are great without the locking pins and victors. We have no hard data to help with why the Denso's overheat while under very light load with the jags. I think it has something to do with the high switching frequency of the jags interacting with the PTC causing it to self heat. I would like to see First allow the removal of the locking pins. Its easy and improves the performance of the motors. However, The bypassing or removing the PTC is much more questionable. It's an actual modification of the motor. So if you use the window motors, use victors.

Thanks. I don't regularly follow the Motors forum, so I didn't know so much attention had already been applied to the subject.

We have not had any problems with the cantilever loading on the window motor sprocket. We are still using the original (4) window motors after (6) competitions (on & off-season) and (4) demos. We've got (L&R) spares, but have not needed to replace any originals yet.

We embed a magnet in the end of the sprocket. A Cherry absolute magnetic encoder is mounted on the plate below the sprocket. This encoder provides information on the sprocket angle and (since the drive sprocket on the motor and the driven sprocket on the pivot are both 15T) therefore the pivot angle. This makes mounting the bottom end of the drive sprocket problematic.

Regarding building chains in Inventor, I have a process which works well (albeit a little tedious). I will write this up (it'll be short).
