<DIV>Cool,I know anything above 36 Volts can be problematic as far as getting accidently zapped. But with the controllers they have now I could run a 48 volt AC induction motor from a DC power source. That would be nice as far as smooth control capability and also I could run the motors in mineral oil and would not have to worry about any brushes. However the rpm may be a problem unless I have some type of gear reduction.</DIV>
