On that same note wont a motor rated 230v not last as long at 243V

It will last much longer on 243V than it will on 200

Agreed.

Actually most motors like a slightly elevated voltage. The full load current drops slightly and they run cooler. This is more evident in integral HP 3 phase motors than smaller single phase.

You don’t get into severe problems with over voltage until you approach saturation.

Edit to add:
Here’s a good write up on motor voltage:

I have no idea how my reply posted twice? Tapatalk gremlins....

That’s a good article, I’ve posted it here before in another thread regarding motors and voltages.
