Someone posted a chart of what double and triple wire sizes equal as a single wire last year but I cant seem to locate it. Im wanting to print it out. Would someone with a better memory than me please point me in the right direction? Thanks.

Basically, double is three wire sizes larger and triple is five if I remember correctly. Double 28 is like 25.

Doug,

 

Here's a simple chart I put together based on wire resistance (at an average motor operating temperature) versus AWG size:

Please note the triple wind equivalents are not exact, but rounded to the nearest half AWG size.  To make it exact, we would be talking about calculating wire size equivalents to several decimal places (eg. 27.6875 AWG or something like that).  Simpler seems better in this case.

 

If you're interested in learning about the formulas used to figure this out, (and if you want to calculate those exact equivalents) here is a web site:

It looks complex, but is actually just a bunch of simple calculations all stuck together.  :D

Interesting to see that info in print. Way back when I did double and triple wound drag motors, it was all hit or miss. When I thought

the first pole was filled, I just did the other three with the same amount of turns. I did a lot of arms over when they became too loaded

with wire. And if it worked, great. If not, I would just re-do it. It was very important that I liked winding arms.

Like I said above, double is 3 wire sizes, triple is 5 wire sizes. Close enough I would think!

Steve ......... That is a super handy chart for working on older arms, where space for big single wire winds could become limited.
