If you are in North America, and have 120 VAC to the outlets, what you
call 220 or 230 VAC in your home is actually 208 VAC, unless you
installed some kind of transformer to compensate.


No, that's not true. It's 240V, the transformer has a grounded center tap
so 120 from either side to neutral, and 240 between the hots. You find
208V in commercial buildings and some apartment complexes that are fed
with 3 phase, but not in a house, unless you're one of the few lucky
people to have 3 phase available.


I somehow think that the vendor of the motor made an error. Having 280
VAC sounds to me very unconventional, unless this was some kind of
special installation.


It's clearly a typo and should be 208V.



If it's not a silly question, with the motor in question being offered "on
the web, really cheap", then if it's e-bay, why not use the 'ask the seller
a question' option, or if it's a reseller, use his on-site 'contact us'
facility ? Then there would be no debate about typos and exotic voltage
issues ... :-)
