Hello

i am trying to restore a handful of old small brushed DC motors, about 4 inches long, with an 1/8 inch shaft, slightly rusted and in need of some cleaning.

the thing about them i am not used to seeing is that the 2 normal insulated motor wires are inside of a braided metal flexible tube which is soldered to a post inside the motor that is continuous with the negative wire. The braided tube comes out of a grommeted hole in the side of the motor case, with the two normal small insulated stranded wires resting inside of it.

these motors were used in some old industrial application, but i just want to put them on a silly little robot. I am wanting to replace the old, dirty, frayed wires with new - but do I also need to replace this braided cable that surrounds them? Is it meant to carry current? Can I delete the braided tube?

Thanks

That's just armored cable, it acts as a shield for radiated noise and protects the wires from damage, it's common in industrial equipment. You can remove it without any issues and it will be like any other DC motor.
