Stepper Motor Question

[trekiej]

I do not know if this is the right place to post.

I have a stepper motor, and I do not know if the specs. are right.  The data sheet says 180 mOhm res. and I get 600 m Ohm resistance.  Some of the dimensions are wrong too.
Its number is a 110BYG450C.  Sad enough, the dealer can not help me.  They offered me the chance to return it.  I may do so.
Its Jameco number is 237585.

I do not know if it is a constant current or a constant voltage item. The specs. seem to point to constant current.

Thanks.

I talked to them 3 times already.
I will take it to school next monday and use their inductance meter.
I still may send it back.
Thanks.
Rick.

I was able to get it to step by using a wall transformer.
It was rated at 6 VDC and 300 mA.  My meter said it was 14 VDC. : (
I found out that it can be used as a unipolar and bipolar motor.  In bipolar configuration it can be series or parallel.  The information is not for the exact motor so I have to be cautious.

Thanks.

Hello.

@ weirdami

I am building a plasma/cutting torch rig.
It will be about 10' x 5' x 2' in size.
I  am working toward being an Industrial Electrician.
This is one of a few machines that I want to build.
The motor is about 1/3 to 1/2 of the pictured size. ( on spec sheet)

XL = 2 pi F L
I need to check on what frequency would be the best.
My multi-meter works to about 400 hz. (darn meter)

@ DamageX
I was wondering if that was the case. I did not have a Load to test it.  I found out basically what I needed.  I did not pursue it more. What is your electrical experience?
Thanks.

I have a 7805 that I could use.  I do not know if I am giving it the right power.  I hear PWM is a way to get the right Amps with higher voltages.
I need to learn more about chopper power supplies.
I do not need a diagram, thanks.
I am getting closer to putting this thing together.
My family had more concrete poured and it will be soon that we move the machines around.

I am low on the funding right now.
I hope to finish up a book on Linear Electronics.
I need to finish the semiconductor and OP Amp sections.
I wish I had bought a motor with clearer specs.
I like my supplier but they let me down this time.
