Correct wire for stepper motors??

[RocketBoy]

Thanks for the reply Clive, appreciate it. I was tempted by series so the motors run cooler, the machine I'm refitting is a Denford Triac so didn't think I would need the extra speed of parallel. Very new to all this so would appreciate any advice. The kind of work I will be undertaking is model engine parts so mainly Alu, Brass and Steel.

Your thinking in this case is correct and for Mill then Series will be best connection because it will provide more torque lower down the RPM curve. But this will drop fast as the rpm rise. However you have half decent amount of volts at 70 so will be fine for Mill.

Use 1.5mm CY cable for these motors. Shield just the Control box side like Clive suggested.
