I would HIGHLY recomend you find Mariss's Mystery Motors post. I think there is a copy on the list of links on the home page of this site.
For example, a round body NEMA23 single stack motor is ABOUT 5 watts. Measure the resistance and you get the first part of the answer. Watts = Volts times Amps. Volts = amps times resistance. Since you would know resistance, you can start to work out the answer in a very safe and practicle way. If the motor is less than a NEMA23, it is not worth the effort as you can buy a known rated motor NEMA23 for under $20.00 Dave --- In [EMAIL PROTECTED], "Robert Williams" <[EMAIL PROTECTED]> wrote: > If I try to determine coil terminals by connecting 12v car battery (negitive) to a stepper terminal and touching other stepper terminals with the positive, WILL I HARM THE MOTOR??
