Most [1] 8" droves had mains-operated spindle motors, often 115V

Oh, I'd be happy to change the pulleys and reset the belt tensions. The
problem is _getting_ the pulleys. Do you want to be the chap who phones
Seagate and says 'Hello, I think you used to be Shugart, do you have the
60Hz conversion kits for the SA801, SA851 and SA4000 in stock'
Yes I could make them. But there's the problem of getting the diameter
right -- if any of my drives use a Vee belt it's not instantly obvious
which diameter to measure!), 'crowning' them properly, tapping them for
the setscrew, etc. All doable (and I have the tools to do it), but not a
quick job. At least no whne you have a dozen or more drives of assorted
models to convert. A motor-generator set might actually be easier!

Oh come on, The Great Dr. Duell isn't afraid of replacing SMT chips on boards,
but is afraid of having to change a few pulleys? Something sounds fishy
here...
