EPSON Step Motors

Hi folks!

I am a student of Computer Engineering and I intend to build a robotic arm to do computer controlled movements. I need to have at least four step motors to make the robotic arm has total freedom in the three dimensions axes, I have that motors already, but three of them are EPSON step motors that I have not found any datasheet or specification:

EM-483 EM-326 EM-323

If anyone could help with this motors I would be very glad.

Thanks.

It won't tell you anything about Epson motors but there may be some useful stuff in stepper motor basics - you have not said whether you are already familiar with them.

It may be worth posting a photo of the motors with some dimensions. How many wires have they? What is the coil resistance ?
