Question: How to choose the wire?
April 30, 2011
Yeah, I know this should be the basic question but I flip the page too fast and skip that chapter.
OK, the situation is the wire getting very hot when motor is running. Basically there are 2 sizes of wire I am using, thin and thick. From the image below the battery wire is thick one and the wire on controller is thinner one. Also, wires from motor are thinner, too and that's why I thought thinner wire might work as well? Now, please notice the wire after the connector from battery become thinner, this is the section getting hot when operation is going.
Do I need to replace the thicker wire in that section?(battery to controller) Or if anyone could please tell me how to pick correct wire for bigger current?
Now I just came up 2nd question. Each motor draws 60A max and the controller could handle 50A per each channel. Does that mean motor won't run up to MAX speed? I know it's not good to reach max speed but just curious.
