AMP 5034-231 steppers, any info?

[Splint]

Hi,
I have some stepper motors which I cant find any info on. The only markings on the case is AMP (which looks like it could be the manufacturer) 5034-231 and Made in Japan. There's 8 wires coming out of it and the body is 2 1/2" long and 3" in diameter and a 10mm diameter shaft (it's the type with the shaft out both ends). If anyone has any info please share.

Thanks
Splint
