I have access to Igus Cabletrain wire that has 4 pairs of 24AWG stranded wire with an aluminum shield plus a braided shield. I think this wire will work great for the servo encoder connections. But can another set of wires be used for the plus and another set for the minus side to drive the motor? I would strip all eight wires at the ends and combine them into one connection in the controller and the other end at the motor. The maximum length of wire to a motor would be approximately 20 feet. So in total per motor I would have one cable for the controller, one cable for the plus and one cable for the minus. I would ground the shield at one end at the controller enclosure.
When I strip the wires and roll them together they form a wire somewhere in-between the size of a 14 and 12AWG wire. The motors I plan to drive state the maximum voltage is 150VDC and maximum draw of 9 amps. Is this idea feasible or am I even in the ball park?
