well of course they don't run.
I use them for my vac hold down and they have never sucked dust. but they are under heavy load since they have very little air flow through them. My first one died 2 weeks ago and my other died today. I have run my machine about 1100 hours and I did not use them all the time so maybe 600 hours or so runtime.
of course I was going to order a motor that is a drop in tomorrow. but I need a new vac tomorrow as I have been pretty busy. so there goes another 465 out of my budget plus another 170.00 for another motor.
