If you use one of the kit motors, you may have to "leak" a little of the vacuum to prevent the motor from burning up due to the strange load produced by the blower with the inlet blocked.
Al, this isn't a problem. Open up an impeller type vacuum and you'll see what I mean. Our vacuum only takes 1-2 amps when the vacuum is working. Oddly it was pulling 5 amps when there was no vacuum. Leaking air would only cause more of a load on the motor in this type of vacuum.
