How to apply statorade on a 9c motor

[alexscard]

I watched the video of the producer where he drills a crystalite but..i didn't get exactly how i suppose to choose the place where to drill, with my motor. I could also open the motor if needed, but i'd need some help in order to understand where do i have to apply this ferrofluid to my 9c hub
thanks!

You want to choose a place to drill where it won't damage the windings or cable harness inside: see the basic example in the video: https://youtu.be/JZU-mhlNcqE?t=88

Video - Interesting about the bathroom grade silicone around the cover plate with it still installed.
Canadian weather is cold, freezing then when you ride the motor warms up so the silicone still holds on through the temp changes.

Yeah but the point Is that i didnt get where this statorade thing has to be applied in order to conduct the heat. What part of the motor has to touch?
And btw, how i know where to drill in order to dont damage anything? I dont have xray eyes

Hint: Not near the outer edge, where all the wires/windings are on the stator.

Study this pic. You can avoid most wires if drill near the middle of the case, but better yet, on the freewheel side, opposite where the phase wires enter the motor. I drilled just outside the biggest cog of my freewheel, tapped the hole, and plugged it with a small set screw with loctite.

The Statorade naturally flows to the outer edge of the motor, and the iron filings bridge the gap between the stator and magnets of the housing/rotor in order to conduct the heat from the stator to the motor body.

ok, say that i plug the statorade where i drew the red X


but then, i don't know how is made, even if it is a fluid or whatever, but i just can imagine that if i put it there, there it will stay.. how can it go on its own where it is needed?(that where is it btw,on the edges of the motor?)

Your picture doesn't display.

Physics; centrifugal force.
Statorade is metal particles suspended in a fluid. See "ferrofluid"

When you drill, put some
Masking tape on the bit so only about 1/8” is exposed. That will stop you from overshooting once the bit gets through the side plate.

Pick one of the disc brake mounting hole and using a drill size that won't wipe out the threads drill through the casing carefully only as deep as necessary. Insert Statorade via supplied syringe, put a bolt in place and call it a day. As mentioned the Statorade will distribute itself to the outer stator naturally.

I have a 9C dd hub from Grin that has a thruhole drilled thru one of the disc brake mounting holes. In fact it is labled "Statorade Fill Port." So you should be good imitating that method.

well, thanks for the answer. In order to be sure not to do errors, i'm still wondering how to understand on wich side of the motor i should drill.
this is my motor: https://photos.app.goo.gl/AYzHUjj8hADwToqh6
So from what you're saying, the side is the one where there is the disk, right? And if i just drill in any of the disk hole i will make it? How deep do i have to?
Once plugged the statorade, i just have to put again the motor on the bike and go, and it will go in the right place on its own then?

a was looking to this guide: https://fasterbikes.eu/en/accessories/hub-motor/219/10-ml-statorade-ferrofluid-magnetic-cooling-liquid
they opened the motor and putted the statorade exactly over the coils. are you sure that just making a hole and plugging it inside will have the same effect?

yes ferrofluid is magnetic that and the centrifugal force moves it towards the edges of the motor

grin were the first people to sell statorade and the initial application video they posted is still valid its also more user friendly to just carefully drill a 2mm hole with a dremel etc until the hole is made and then just use epoxy putty etc to seal it

I thought about using the disk hole method, but then didn't want to deal with getting the metal particles out of the hole without pushing some into the motor. I'd do it if I had the cover off, but then I could just put it in directly. I went with the method from the Grin video.
