I have on many occasions run a motor circuit with the controls not only in the same conduit, but in the same cable. I would get a 9 conductor cable (usually for TC rated systems with a remote start/stop PB) and run 3 motors leads at 480 and the controls at 120 VAC. I never had problems. I usually would not run DC with the motor leads and like everyone else, never analog signal wire without having a shield. There is no rule that says you can not do this as long as the same insulation level of the wires are maintained. This is protect the circuits in case one of the 480 VAC wires has an insulation breakdown, the other wires will have the same insulation level and therefore not be breached.
