The PDF I linked is showing motor performance for a particular drive, as you
say you don't get the maximum performance out of a drive unless you're using
the proper driver & power supply for it.

Big drives means high voltage ( 130v rather than 50v); those motors in that
PDF would perform better on a different drive.

You would also wind up spending a lot more money, and as most people know as
you move up the scale the returns start to diminish - twice the price
doesn't necessarily buy twice the performance.

The point is don't spend all you money on the motors, you'd be better off
buying cheaper motors and better (matching) drivers & a power supply for
them.
