Cable broken
Cable broken
(OP)
I am designing a robot. However, during the life test (several weeks), part of cable for steppers are broken. We find that the cable (AWG 18) are not flexible enough for frequent twisting motion (+/-270deg). What type of cable I can use?
RE: Cable broken
> braided wire; since the strands are not in fixed relationship, the ability to slip increases lifetime.
> high ductility copper; this is hard to get and expensive, but some suppliers can provide cable with the higher ductility, which should reduce the damage.
> large service loop to minimize the mechanical deflection of the cable

RE: Cable broken
I have seen some cable used in other robot and it work. The cable consist of very fine conductor (about 0.05mm) and the size is AWG18 (outside dia. 2.5mm, the space is not enough for a large bundle of wire). The insulation layer is made of PVC. I am looking for this kind of wire. Where I can find this kind of cable? most supplier provide conductor only with 1.5mm or larger, it is easy to break in our case.

Cicoil was one supplier of molded cables, but I don't know if they make them with that low a profile. Kapton flex cables are used throughout the printer industry.
