I built a vacuum hold down system for my Buddy table. It was working great and 20 minutes later I smelled something hot, you know, like the odor of motor insulation frying, then the vacuum motor slows down over the next minute and finally dies. I built a box similar to this one:

I allowed about 1/4" clearance around the exhaust side tube thinking this would be plenty of air space to allow the heat to escape. Should there have been more clearance around the exhaust tube opening or did the heat build up too high inside the motor side enclosure and fry the motor? The one pictured above does not show any clearance around it's exhaust tube so I thought it strange this happened. Any ideas would be greatly appreciated.
