Re: Affordable AC Motor?

I'm still relatively new to motor theory but as I see it the voltage 
limit in an AC motor (brushless DC) is not a wiring issue but one of max 
rpm the motor can mechanically handle. a wire doesn't have a voltage 
limit (except for maybe insulation but maybe that's not an issue in 
practice)

maybe someone else knows, am I right that voltage for an AC motor is 
only limited by the the rpm it can handle? (assuming current limitation 
of course)

further, as I've stated before, why not look into what motors the 
several available hybrids use today? once in a consumer mass production 
environment the prices tend to be much more reasonable. I was at a car 
show the other day where I saw the very nice Lexus LS600h which although 
still a mainly gas hybrid, the salesman claimed 530Nm torque on the 
electric motors alone. sure a lexus part could be expensive but maybe 
someone could look into spare parts cost of some of the more mainstream 
SUV hybrids in USA. some specs and a price. would it kill someone is USA 
to do that? : )
is it an EV developers list or a rest home
