Gentlemen,
The Gettys are three phase.
The encoders are 1000 pulses/rev giving 20,000 counts/in on the
linear axes and 2000 counts/deg on the rotary axes.
The Gettys are listed as 33 amp output. This I believe is 100%
duty cycle. I don't think this is peak rating.
I like the idea of using components that are as simple as possible
and having EMC do the work.
I will try to build an amplifier to use. If anyone has
suggestions/plans/gotchas please feel free to let me know.
I am trying to make a sow's ear cut parts. If I can get this
machine to position the tool tip to +/- .005 I will be very pleased. I
don't need speed I need reliability and strength. The strength is in
the cast iron.
This will let me cut parts to +/- .010 all day long. If I want
something closer than that I will put it on a different machine.
thanks
Stuart
