Step Motors

Hi to everybody:

My name is Rafael Lezama, I'm live in  Puebla, Pue. México.
I am electronics engineer and I like a lot your web.
I have a question, I hope someone can help me.
I have some steps motors but I haven't found information about them.
I could already identify some cables, but I can't make run them.
I send some technical data and photographs of these engines, and hope can help me.
