Can I drive this steppers with RAMPS 1.4? (2 replies)

Hello,
sorry for my question, may be OT, but I can buy these stepper motors ( 23LM-C355-P2H, 17PM-M007-02, 17PS-C103-P1 from Minebea Co., Ltd.) for good price. Problem is, that I can't find some datasheets of 17's stepper. That's some custom motors. Only info I have is: Minebea 23LM-C355-P2H (Olivetti 57BYG 060), 56x56x50mm, 1,8°/step, 0,6Nm; Minebea 17PS-C103-P1: 42x42x39mm, 3,6°/step, 0,22Nm; Minebea 17PM-M007-02, 42x42x34mm, 1,8°/step, 0,15Nm.

Is there any way to find more info like Voltage? Can I drive this motors with ramps 1.4 if yes so what power supply I should use?

Thanks very much for any respond!
