Electric Vacuum Motors
By Tim L'Amoureux

Ragtime Automated Music uses a 220 volt motor run on 110 volts to
reduce its roar.  It's still noisy, but the idea is not a bad one.

I have used a boost/buck transformer on a pneumatic switch to kick the
voltage up from 110,VAC to 150VAC, when the loud perforation is opened
on the O-roll.  The loud perforation usually accompanies the crash
cymbal perforation, but not always.  It was an idea that didn't work as
expected, since it took so much time to speed up the motor that the 
effect was lost, because the perforation closed before doing much good.

But using a 220 volt motor on 110 volts does reduce noise and should
increase longevity.  Using a boost/buck transformer can be a pretty
good way of controlling the vacuum supply.  My boost/buck had many
taps; so it was pretty versatile. Just an experiment that sort of
worked.
