stp 58D211 -02 Shinano kenshi (4 replies)

Hi every one, i've bought an used stepper motor with the "STP 58D211 -02" code on it. it's of Shinano kenshi's old products. All I know about that is, it is a 1.8 degree stepp motor with 1.5 ohm resistance per stepp. I want to know more about it's used voltage and torque. So if any one can help me I'd be pleased if he/she send me proper information.
