Mariss' Surplus Center Motor - Thanks

Mariss,
Thanks for the tip on the Surplus Center motors. I got two of them.
They are Pacific Scientific treadmill motors, real well built. They
spin at about 30 rpm with a single D-cell. They have flat endplates
with 2 1/4-20 through boltssoend mounting them will be a layup.

I'm planning on using one as a knee motors on my large servo mill.
If its well enough built to run on a flashlight battery it should
have no problem with 76 volts at 10 amps. I unfortunately won't have
any time until after Thanksgiving to mount an encoder and do real
testing.

I just hope it can lift a 1,200# table/knee with a 2 or 3:1 belt
reduction on the motor and a built in 10 turns/inch helical
gear/ballscrew jack. The knees ways are turcite lined and pretty
slippery.

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.
