Info on Eastern Air Devices ??stepper??

[mpmarino]

Hi folks,

I'm just getting into this CNC stuff so pardon my ignorance please I'm a surplus junky and a scrounge, I like to keep my hobbies cheap - as does my wife. I have found some motors that I believe are steppers. If they can prove useful I could probably source a bunch of them, but if you could take a look I would appreciate it.

Label:
HYST SYN MOTOR
EASTERN AIR DEVICES
21V 173.3HZ 2PH .02HP
2.0A 10400RPM CLB
CONT DUTY
H34NHS-4
9732 08813
<end>

4 wire wh/r/bk/bl
1.3 ohm between wh/bk and between r/bl

It seems to be a stepper type motor when I play with a battery.... Thoughts??

Thanks,
Marc

OK, no takers

Lets try this....

does anyone think it's possibly a bipolar stepper?

it it possible to test without a controller?

thanks for reading..

Just an idea.

Maybe it is a synchronous motor from the description.

If you know where is it dismantle from, it will give you a basic idea what is the function of it.

Thanks for the reply!

Yes, I think is is a synchronous motor by the description as well. I notice a lot of steppers are called synchronous/stepper motors. It seems like it was used to control a prism in some sort of laser assembly.

The reason I persue this is that there are 100 or more that may be available at a very low price .

From the description of 10400RPM @ 173.3Hz thats a 2 pole synchronous motor, so I don't think you will be able to use them.
Most steppers cannot reach 10K RPM and are 200+ steps/rev.

Thanks Aaron,

with that, I'll drop it and move on.
