Cable for two phase stepper motor
Cable for two phase stepper motor
(OP)
Hi! I have a two phase stepper motor to connect to a driver.
The maximum voltage is 70V and the maximum current is 5A. I would need a new cable at least 7m long.
There is already a cable of 2m long with the motor (too short) with :
4 wires for the 2 phases
1 PE wire
1 shield
However, I don't know much about cables I should choose to extend it. Could you give me some direction to search?
Thanks in advance.

But a problem remain for me : how can I know
-the Gauge Size
-the Conductor Count
I had already called both manufacturers who didn't help much. They told me the 2m cable had a diameter of 6.4mm
Can I use this information to calculate the Gauge Size?

Personally I'd probably use stranded sheilded 18AWG with a drain wire connected at both ends. You could probably use 20AWG if you are pressed for dollars.
