Cheap Servo Motor?

Hi,

I stumbled across this motor:

http://www.surpluscenter.com/item.asp?UID=2003070308293941&item=10-
1931&catname=electric

It's rated at 4800 RPM at 120VDC with a continuous rated torque of
250 in-oz.

Working the numbers gives a Kv of 25 volts / 1,000 RPM and a Kt of
33.8 in-oz per Amp.

At 72 volts you would get 2,880 RPM and draw 7.4 Amps at its rated
torque. The power output would be 533 Watts or about .71 HP. I don't
have this motor nor have I tested it with our G320 drive but it may
work.

At $24.99 it may be worth a gamble.
