Greetings All,
Please excuse my electrical ignorance, I am a mechanical engineer and most of this seems like voodoo to me. I am building a 5' x 10' plasma table with the possibility of router use now and again. I am from the school of more is better and have been sizing things accordingly. I have purchased the MP1000 from candcnc, as well as my gecko 320s with the intent to drive my 1100 oz peak 90V nema34 MCG ID33004 servo motors from camtronics. My last question refers to power supply sizing. I am still not certain wether I will try to build or buy, but the logitrol 700W Power Supply 75vdc interests me. As I understand it, the higher the volts, the higher the rpm? I wanted to run these motors at a higher rpm then reduce down. I was suggested to get a 36vdc power supply and direct drive them as they were strong enough. I wasn't worried about strength as much as efficiency and accuracy. So I guess my question is if cost isn't the driving factor, what would you recommend?
Cheers, Erick Davidson
