800 VDC presents an extreme arc flash hazard.
The other thing is can the motor insulation take double the voltage?
To me doubling the voltage and increasing the amount of heat put off by the windings is a recipe for short motor life.
Are the wound rotors brushless?
In industrial motors only specialized ones can be started on double voltage. And this is only allowed for a few seconds.
Any normal motor would be damaged and quickly ruined by double voltage.
Also you should take into consideration that it appears that all these motor drive bits and pieces were designed to prevent anyone from swapping parts around like this.
With electric vehicle motors and drives these motor and drive sets appear to be designed specifically for each vehicle.
Higher voltages are not inherently bad. Anything over about 90vdc is easily deadly.
It's once you start going over 600vdc that you go from deadly to spectacularly dead with bonus fireworks show when there is a fault.
