Some time ago I picked up some surplus stepper motors and have had no luck finding the exact specs for them, I am wondering if anyone might also have acquired some and found out the data on them?
They were made by Minebea, bi-polar, frame size NEMA 23 , each winding measures 1.5Ω They are marked p/n 127K47820.
tks

 

I can't quite find the exact one, but I got pretty close:

Like transformers, it's quite easy to get specials made with one's own particular requirements for resistance, inductance, torque etc. and different stack heights.
Try an e-mail?

 

Thanks, I did find those when I first started looking, I believe they were custom made for printer/plotters etc.
I will maybe try again and see if I can obtain a contact!

 

Update, Info found, if anyone else should ever need it.
