Hi, I am new on this forum and glad I found it. I am working on a work project to develop a heavy duty mobile cart. We are using two Heinzmann PMS 100 motors with gearing and a pair of Sevcon G4 controllers. I would like to get the motors working on the bench first . Anyone have suggestions for a DC power supply to do development? The motors are rated each for a max of 67A under full load. I don't really want to use batteries just yet. I though of a 50-100A 33-40V DC supply should work initially? Thoughts?Suggestions?
