Let's be fair. A motor on the bench on it's own will spin up
fast, but the difference between that and an RP06, whatever, is
the rotational mass of the disk pack and whatever else is in the
drive train. Istr, this includes flywheel material in some drives
to damp the hunting that you normally get with ac motors at low
load. Once the drive is spun up, there's only the frictional losses
of the drive train and head windage to overcome, yet such motors
were often rated at 1/2 hp, to run close to slip speed at the low
load

We had a load of 300Mbyte washing machine drives at one site and
having stripped a couple down for parts, revealed a very handy
good quality single phase capacitor start induction motor. You
can make a very good machine tool drive from such a  motor :-)...
