text: <s>[INST] Need helping sizing drive Summary: I'm in need of help sizing a motor and drive. I may be incorrectly using Motion Analyzer software. I’m attempting to size a motor and drive for an application I’m working on. It involves winding paper at maximum tensions of 15lbs at a max speed of 50 feet per minute. That would be considered worst case scenario. I’m using the Motion Analyzer software and am having a hard time deciding on motor and drive. From the load alone, the calculated horse power needed to keep a tension of 15 lbs and 50 fpm is .0227 horse power. It would be ideal to run this at 120V. However, when I’m putting in these parameters to motion analyzer, I’m getting barely any solutions found. The solutions that I do find are not very good either. For example, the one solution offered to me gave me a 6.4 KW motor with a 3 KW drive. Now, why would I need such a large motor when working with only .0227 horse power? Would this have anything to do with trying to use the drives and motors at 120V? I realize this would require a larger current. Is it possible that only more powerful motors/drives are able to handle increase current levels? Or is it likely that I’m modeling my application incorrectly? [/INST] If you're using Motion Analyser, could you share the file here? \\n </s>
