They are both different animals, one is a 24krpm and the other being a DC motor is going to be limited to at best, 4krpm.
DC motors are fine in the lower end rpm, and the best drive for them are the KB or other, PWM version drives, the KB225D is not a bad drive, but the 1ph SCR drives are not as smooth a quiet a control as the PWM drive versions or a 3ph SCR drive.
Usually the High rpm water cooled induction motor type are limited to a fairly high minimum rpm, due to their low inductive reactance at lower rpms.
Not observing the minimum usually burns them out.
