All teams should be aware of the cooling issues with motors. On the new drill motors (bare bones) you will notice that the end opposite the brushes and fan, has two slots cut in it. The fan is a centrifugal unit so it throws air out from the edge while sucking in at the center. With that said it is easy to see how air is drawn in at one end, passes through the motor and out the fan. Disturb any of these three mechanisms and high heat will result. Don't block the intake, don't block the brush assy, and run the motors at sufficient RPM to let the fans do their job.
