Best High RPM motor,based on the Bendini design, very easy to make..Brushless Motor

If your looking for high RPM, this is that machine, for procuring high RPM,just remember to build it with safety in mind, i don't know much about the power input, but i am sure there are many variants of this design out there.from two phase to three phase, i think this is three phase....the noise out of this tells me, its possibly three phase, so if your into testing or prototyping, then use a three phase generator...,for those high rpm machines, this is really high rpm...so be careful, don't use soft metals...notice that he uses epoxy to contain the magnets, this can be dangerous on a high rpm device,if it were me, it would have slots...instead of epoxy.
