I believe another way to study this is to set the stepper (or DC motor) up as a generator, maybe in a drill press. As you increase speed, the output voltage goes up. The output voltage is the minimum voltage you would need to supply if you wanted to drive the motor at the current speed. I'm sure there are some other issues that may change the required voltage a little, but this can get you in the ballpark. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
