Some industrial electric motors operate in the kilovolt range, even above 10kv. These motors produce several MW of power, and are badass.
EV trend in performance vehicles is to use higher voltages. Porsche, Koennigsegg use nearly 1kv.
When a controller is involved, lower is generally better as you have less losses thru switching, so I'm told. And obviously high voltage allows lighter smaller conductors for a given power level. Of course there are issues with insulation the higher the voltage you run.
Aside from those 3 things what are the pros / cons of very high voltage in electric motors? Will we see performance cars with voltages over 1KV in the near future?
