Im not grasping the whole regenerative breaking adding another motpr concept.. as for the questions. I dont know. That is what i am tryong to figure out. I need to know how much power will be used to operate the 750 or larger watt motor i posted the link to at full power. If someone can give m e an answer, preferably numerical, to that i can see how it will draw the current in comparison the initial500 watt load. Sorry to,keep annoying those of you who see this as simple, i just dont without numerical proof...
