[Shop-talk] 3 phase and phase converters

[Gerald Brazil]

Dan I run a 3 phase mill on a Variable Frequency Drive.....and love
it....you get infinite speed control with full torque. You should however
provide a supplementary cooling fan for when you are running on a slow speed
since the fan built into the motor won't flow enough air. If you are not
happy with the static phase converter, investigate a VFD. Everybody I know
who uses them wouldn't do it any other way.

I recently purchased a small Bridgeport Milling machine.  It draws 3.3 amps
at 480 v(three phase).  I also purchase a used static phase converter.  Has
anyone ran a milling machine this way or has experience hooking up one using
a phase converter.  You help is appreciated. Dan
