It sounds like that "max" voltage is related to the max voltage to achieve an rpm no higher than the max recommended rpm. If so, then all the different winds should have a max voltage rating that is different.

Take for instance a 34 turn feigao with a kv of 490. Does this mean it can take the 71v needed to achieve 35,000 rpm?

Usually, the limiting factor for voltage on any device is the dialelectric strength of the insulator - just like the limiting factor for current is conductor size and/or how much power it can dissipate (but power is more of a voltage and current factor)...
