    Difficult to know without seeing the layout of the machine and control box position etc. But If it was me then I would run a single cable from the control box close to the motors and into a terminal box, then split off from there to each motor. This way only got 1 x 2 core wire running through the machine.

    You don't really need to be a genius because there are plenty of Cable sizing calculators and web sites explaining correct sizing etc available online if you are unsure. Like this one.

    However, 1mm will work fine for your application with short cable lengths.
