Hello my whoop friends! All the important info is here in the video description! This video is not a step by step tutorial. It's just meant to help you and give you motivation to start dewinding whoop motors yourself. The first step is to disassemble and unwind/ dewind the whoop motor. That's what this description and this video is about. I'll hopefully show you the second part (rewind the motor to a new KV or and with thicker wire) in the video part 2 in one to two months. Until then, you can practice disassemble whoop motors with old motors that you no longer need. Then you can take the first step. I hope I can give you motivation and help with this to dewind your first whoop motor. Write me your experiences in the comments and please share the data from your engines (motor name and kv and how many turns) with me.
The Motor in this Video is a VCI Spark 8028 27000kv.

► Steps to disassemble / dewind a tiny whoop motor:
● Removing the heat shrink tubing from the motor cables
● Removing the C-clip
⚠️use your favorite technique so that the C-clip does not get lost⚠️
● Separate the stator and motor base from the motor bell
⚠️be careful not to lose the small washers and write down the order!⚠️
⚠️Take a photo or note of the order of the washers⚠️
⚠️Store all small parts safely in a closed container⚠️
● Screw the motor base to a holder
(old carbon frame, homemade holder, etc.)
● Clamp the stator in homemade clamping jaws
⚠️No matter which clamping jaws you choose, they must hold the stator well without crushing it, thats the goal⚠️
● Warm up the motor base with stator with hot air to approx. 80-100 degrees Celsius (So hot that you can't touch it for longer than 0.5 seconds)
● Separate the motor base from the stator (if you need/want this step)
⚠️possibly with the help of a screwdriver under the carbon frame / motor base holder to have a lever⚠️
⚠️ This step is not always necessary⚠️
⚠️Sometimes the PCB ring comes with it and sometimes it doesn't if it's glued on with epoxy. In this case you have to cut the enamelled cables to get the stator away⚠️
If the PCB boards are glued on, you can leave them as they are or if you want them gone you have to warm up the motor base with the PCB board again to approx. 80-100 degrees Celsius and then carefully lift the PCB board all around with a small slotted screwdriver.
● Untangle and arrange the enamelled wires on the stator
⚠️Note the Termination of your motor. Is it DELTA or WYE Termination?⚠️
● Start unwinding the one cable that is free and count the turns and write them down on a piece of paper after each coil! Our whoop motors have three phases and each phase has three coils.
⚠️You have to know that there don't always have to be the same number of turns per phase. For example, some motors have 8,8,9 turns per phase. Or 8,9,8 turns. Make sure you count correctly.⚠️
⚠️Sometimes there is epoxy resin in the enamelled wire. In this case the stator must be heated to a temperature of approx. 80-100 degrees Celsius during the entire dewind process⚠️
● With some motors you have to warm up the stator again and press out the upper ball bearing.
⚠️After you have dismantled all parts of the Bruhless motor, you can clean it and possibly heat it again to remove any epoxy residue carefully with a fine plastic tool. You have to be careful not to damage the green insulation layer on the stator!
If this happens then you have to insulate the open areas on the stator again with a suitable material. (I heard it works with nail polish/nail vanish)⚠️
Afterwards, all parts of the Bruhless motor have been disassemled and are ready for rewinding.
I hope I can do the rewinding video in the next two months.

Great content. 👍🏻. Love that little vice.

Yeah. Now you got me intrigued. Only just took a motor apart today to clean it out and was wondering about rewinding. Will definitely be digging some old motors out and tearing them apart in anticipation of the next installment. 👍

Nice to hear! Please share your findings (motor name and kv, turns of the windings) with me here or in this facebook group: facebook.com/groups/457333120275712

I've gotten this far (and it's really interesting to take a motor apart!) but what would be _really_ interesting is if you could manage to re-wind a set of motors (to a KV you like) and have them work again. Looking forward to any future exploits of yours ;-)

Nice! Please share your findings (motor name and kv, turns of the windings) with me here or in this facebook group: facebook.com/groups/457333120275712 And yes PART 2 is hopefully out in about 2 Months..
