Billigt servosystem!

Kan dessa vara något att ha?
Ametek
Hittade lite text på CNCZone som verkar handla om samma motor:
AMETEK 38VDC 900 RPM MOTOR
900 RPM AMETEK, #965922-101. Permanent magnet DC
motor rated 38 VDC nominal. Reversible, ball
bearing. Max. rated rpm is 1300 max. Armature
current before permanent demagnetization is 12
amps. Torque constant is 50 oz-in per amp.
Terminal resistance 20 ohms +-20%. Voltage
constant is 37 VDC per 1000 rpm. When tested on 38
VDC, we recorded the following data: No-load spedd
1100 rpm @ 0.260 amp. With a 100 oz-in load the
shaft speed was 900 rpm @ 2.3 amps. When tested as
a generator at 1000 rpm, the output was 5.8 amps @
12 VDC. Shaft: 5/8" dia. X 1-5/16" long. The
opposite end of the shaft has a turned down
diameter and a flat mounting area with two sets of
tapped holes. This was probably originally
intended for an encoder or tachometer mounting.
This shaft has an outside dia. of 3/16" and is
approx. 3/8" long. We do not have the encoders
whtat were mounted on this motor, but suitable
encoders are probably available from encoder
suppliers if required. The motor has five #10x32
tpi tapped mounting holes on the shaft end of the
motor body. Electrical connections are via 3-1/2"
long flexible wires. Dimensions: 4" dia. X 4-1/2"
long (excluding shafts).
Om man håller sig på max 10A så bör man kunna ta ut 500 oz-in eller 3,5Nm
Enkoder verkar man kunna köpa för ca 20 dollar, tex:

Och för en riktigt billig kontroller:
