Hi all again.
As usual I will bug you guys/gals about the junk I collect on the flea market.
Now featuring two stepper motors, labels read following:

1st:
( Appears to be Bipolar, 4 wires, 3 Ohm per coil, has a small window at the back end were u can see the wirl spinning)
MUIRHEAD
H.F. HYST.
MOTOR UNIT
K-164-B
No 456304
mF
TS 1.3 (number 1.3 is engraved besides 'TS')

2nd: (2 green wires, 2 red wires, greens have 880 Ohm, reds have 350 Omh readings)
Oriental Synchronous Motor SH1K
1W 100/110V 50/60~ 0.13/0.13A 1/0.8mF 1500/1800W/M (or H/M?)



Any takers?

Should I quit draggin garbage into my house?
hehehe.

Konstantin.

Build/buy a simple bipolar driver then you can test any motor you gather (either bipolar or unipolar). With scraps, especially motors from non-familiar manufacturer, testing is the easiest way to go

How come the flea markets that I go to always have useless crap? What do I need with 18 gallons of pistacio scented lotion? Or a, 8 foot blanket with a deer on it?
Abasir...do you have any suggestions on a "simple driver"?

[Konstantin]

Actualy a great IDEA. To have a simple battery powered driver board with alligator clip for easy hoockup.

Well I know were can I get an alligator clip , but the driver....
using a bipolar driver would do for unipolar steppers as long as I connect them correctly, gotta bring a multimeter with me also. Next time I go to a flea market I ll go prepared.

Now the Muirhead stepper I got is apparently from MuirheadAerospace. It will be difficult to get the specs of the motor. If the coils of this bipolar have 3 Ohm, what voltage / ampere could I appy the most?

>>> do you have any suggestions on a "simple driver"?
Bipolar or unipolar? Unipolar would be simplest

[Urgundiz]

Yep would be simpler but not so universal, with a bipolar driver you can test unipolar steppers, but with a unipolar you cannot test bipolars...
