Modern motor controllers can be quite tolerant of significant voltage variation. However, I doubt they're changing the voltage.
I'm not a power systems engineer, but it could be that changing the supply voltage would be a matter of changing taps on a transformer.
As for flag day - I remember as a kid when there was a changeover to 60Hz in the hydro system. (Was it 20Hz before that? Something much lower.) Anyway, every electric motor in the house had to be changed. Must have cost a fortune.
Had another power out at my building. Just long enough to flip a few switches. The TTC line is hot now so that's probably not it. Although they did say they were going to run a streetcar on it soon. I think this one is probably the result of seasonal switching as they leg out the grid at the CNE grounds for the Indy etc... As the uuid corruptions I experience only seem to affect the secondary disk, I just mount it as needed. I get a SSRT error 16 on the unmounted ATA3 but the system fscks and boots without having to force it manually. I've popped several previous motherboard living here, but the drives seem to survive and I kind of like the view down ft Roulle st and watching the windmill. I resist the temptation to attribute any of the electrical anomalies I have experienced to it's operations, but it does get a little eerie when the thing is pointed right at you and something happens. :-)
