RE: [CAD_CAM_EDM_DRO] Re: Electrical wizards

In a chopper type drive increased voltage will increase your maximum motor
speed in any size motor. It will not increase you maximum torque (holding),
but will keep the torque from dropping off as fast as the RPM rises. If you
are using low induction NEMA 23 motors getting enough RPM is not usually an
issue. When I had a Sherline it was doing 60 ipm without a problem on a 24
vdc supply and a Camtronics 5 amp controller set to 1 amp.

Different story in a non-chopper drive where an increase in voltage will
increase the amperage and could easily lead to melt down.
