DT-750 complete rewind pictorial.

[Foam Addict]

This tutorial should help you rewind any CD style motor, and gives a basic DLRK or AabBCcaABbcC winding guide.
Each post will encompass one "phase" of the motor, with all teeth in that phase being wound with one strand of wire.

My specific equipment:
DT-750 motor.
Tech Fixx 22g 200c wire.
Wire cutters.
Exacto knife.

First, pick any tooth. This will be tooth one. Wind 16 turns clockwise as neatly as possible while leaving a 2-3" tail of wire. This is the "A" tooth.





Next, move one tooth to the right, and wind 16 turns counterclockwise. This is the "a" tooth.



After that, move 5 teeth to the right, and wind that tooth with 17 turns counter clockwise (I'll explain why later) ,This is the next "a" tooth.



After that, move one tooth right, and wind that tooth with 16 turns clockwise. This is the "A" tooth, and it also completes the phase.



Leave a 2-3" tail, and clip the wire.

While you are at it, scrape the insulation off of the end of the wire wire, and check for shorts to the stator with your multi meter. If there is a stator short, you will have to unwind the phase and try again.

Now that wasn't so bad was it?
Only two more to go!

Unfortunately, I didn't take as many photos as I should have, I do have photos of a different stator being wound, but it doesn't match precisely. I can post them if you would like.

Winding is another "dark art" I'd like to learn, so please post away!

Thumbs up! Keep up the good work.

If you mentioned it, I'm not seeing it. Why did you wrap seventeen winds on the one stator?

Why did you pick sixteen winds?

How did you pick that gauge wire, what kind is it, and where did you get it from?

Now, this is where things get a little harder...
(Sorry, I didn't take pics of this part, I got a little too focused)
This will encompass the bBBb phase.

Find the first tooth you wound, and move two teeth to the right of it. Wind that tooth 16 turns counter clockwise. This is the "b" tooth.



Next move one tooth to the right, and wind that tooth 16 turns clockwise, this is the "B" tooth.

After that, move 5 teeth to the right, and wind 17 turns clockwise, this is the next "B" tooth.



Finally, move one tooth to the right of that, and wind that tooth 16 turns clockwise.

Leave a 2-3" tail, and scrape the end of the wire to check for stator shorts.

Sorry for the pics, I really goofed badly there.

The previous photos will work as a guide.

Actually, I'm wrapping 16.75 turns, but that only counts as 16. The crossing wire from teeth Aa makes most people count it as a turn. It isn't, so they end up with 16 16 15 16, which makes the motor run a little rougher, and heats up the short teeth.

Manuel v over on RC groups got 56oz of thrust from a 16 turn 22g wind at >80% efficiency on 3 cells. Think 19 amps. That's 3 oz per amp!

It is 22g 200c rated wire from Tech Fixx on EBay. It is cheaper and more accurately gauged than gobrushless wire, and also got here faster.

Ok, you are on the home stretch, but this is also the hardest part.

Find your starting tooth, move 4 teeth right and wind it 16 turns Clockwise. This is your "C" tooth.

Next move 1 tooth right and wind it with 16 turns counterclockwise. This is your "c" tooth.

Next move 5 teeth right and wind it 17 turns Counterclockwise. This is your next "c" tooth.

Finally move one tooth over, and wind it 16 turns clockwise. This is your final "C" tooth.

Leave a 2-3" tail, scrape the insulation off the end, and check for stator shorts.

This is how it should look in the end:




Tips: you can use a broken APC prop to make more room on the stator:








Next, I will show how to delta terminate the motor. Unfortunately my soldering Iron died, so that will be later today.
