Wire????

[Rocstar]

Yes but your answer above implied that it was AC because it had a frequency and thats not quite right. It's still DC voltage you're dealing with. Even though it has a rise and fall from switching it never switches direction, it just turns on and off, it always stays between 0 and you max positive voltage.

Correct, PWM is repeating a series of on and off DC pulses to form a square wave, it never reverses direction. Some people think that DC flows on the outside of a wire. That does not happen with any amount of DC voltage or current. "Skin Effect" happens in AC only. But I think we are looking into this too much. Keep it simple, use quality high strand count silicone coated copper wire.

Wikipedia can be misleading...

We still talking about this? I stick to my statement like others have agreed with. Just keep it simple. Also I hate wikipedia for anything factual.

Glad y'all got the point of this thread. Use high stranded copper wire, not just anything laying around in the garage.

Tell Steve to get on the ball and re-stock the 6mm 10 GA wire (stuff on the right in the photo)!

For those interested in reading about PWM and skin effect on the wire and motor.
