Creative uses for servos?

We used a heat sink and heat sink grease on each of our drill motors. This lowered the temp on the surface of the can nearly by half. They worked really great and we never had any overheating problems. Here's where you can buy them and a pic. You should also be able to find them at any quality hobby reatailer such as Hobby Town USA.

As for the colling spray, it is canned air that you buy from Office Depot or Staples or Fry's. When the can is turned upside down, the compressed gas comes out as an ice cold liquid spray. This works very well for cooling the CAN of the motor between matches. It is also very useful for cooling breakers before matches to ensure that they don't trip as much.

The reason I'm telling you all this is from something Andy Baker said that I agree with:

There are so many advantages to giving these designs out. We as a team
feel that giving these designs to other teams “raises the bar” of FIRST robot designs and all of
FIRST benefits.

Last, I would strongly advice against cooling any part of the motor except for the can. You can accidentally freeze the thin insulation off the armature windings or even more easily crack a brush. If you absolutely must spray the inside or endbell at all, do it on a room temperature motor.

PS. Sometime hopefully before the end of the summer I will have a little white paper made of "Tips, Tricks, and Field Side Fixes" that will cover the things above and much more.
