Robert,

Loved your comments!  What I meant was that most of the vacuum motors I
used before took the air that was sucked through the gaps an passed some
if it through the motor to cool it. The AS&S puppy does it the other way
around, pulling in virgin air through the motor instead of through the
gaps and then through the motor...

As Chuck Curran said, these motors really suck!  :^)
