We're using AC BL, what about DC BL?

Hey guys,

We are using AC brushless motors right? I was thinking are there any DC brushless motors out there that can handle higher RPMS?.. I found some that can run 25000rpms, but very low power ratings (wattage)... I was thinking maybe they have more torque than the motors that we are using.. ? The feigaos, Neus, Lehners, Pletts, etc.. are 3 phase AC right?...
