I would interpret the "1000 rpm max" to be the free run speed of the motor at 72 volts (rated voltage), not the max rpm that the motor can be spun up to without power. It's max safe rpm is probably a lot higher. It says it can be run at 144 volts which would double the rpm right there. there is still the issue of the anemic torque output though which would limit its use in a car unless you were going to fit 4 of them.
On the other hand, that NSK motor looks like it would be pretty cool and might work really well if you were rich enough to afford a couple.
