They run hot, have low power output, run slow, cooling fans not as effective due to running slow, etc. Depends on your definition of "fry". As motor winding insulation breaks down due to running hotter than design, internal shorts may occur, and your motor could "fry". If you only use the motor on lower than design voltage for a few minutes now and then, like many hobbyists, you may get away with few problems, just slow and weak output. None of the above is happening. I run them daily and have for a couple years now. I’m guessing my two water Wells and their electric pumps that are rated 110v or 220v, and I’ve been running 110 for 15 years now, 365 days a year will burn out now. It was a good 15 year run……. Quote

Water pumps are very different...your water pump motors are a variable voltage squirrel cage motor. They aren't stepper motors driven by a Variable frequency drive. Which is what a sewing machine motor really is. Quote
