Tidalforce teardown now in Files area

[bill_von]

I put together a document called "Tidalforce disassembly" that
documents the disassembly of the hub motor, if anyone's interested.
It's in the Files area.

Thank you very much Bill!
This could be very helpful.

Sweet!
Yes, optical makes sense (no pun intended) Hall Effect with all those
switching magnets around sounds glitch-prone

I wonder if you could make the motor turn faster by repainting the inside
cover with less segments.

Mr Bill, do you happen to have the same for the front hub? I took mine
apart and am unsure of the placement of several small spacers -- I
know = dumb.

I fear not. If the system is indeed using those painted segments to
commutate the motor, then messing with them would result in the motor
"thinking" it was in a different position than it was in. The
relationship between the magnetic flux of the magnets and the pole
pieces would no longer be maintained, and the motor would become
erratic or stop.

Unfortunately no. I did not have to disassemble it completely, so
that's all I got.

WOW!!!

Thanks sooo much Bill! This is a fine piece of work!

Great stuff,

Hello Bill, et al;

After few thousand miles, my trusty S-750 motor started to make a clicking noise every turn (although presently it appears to be only noise; no functional impact yet).. Obviously this is not good news and I'd like to open it up. I'm coming up short though; after removing the 9 screws around the black circular plate, I don't know how to pull the assembly. I saw others on the web different kind of motors use 3-legged puller or more crudely, a hammer to push it out.. 

Because files discontinued in these groups (http://groups-announcements.blogspot.com/2010/09/notice-about-pages-and-files.html) I can't see the doc you posted Bill. My key issue now is, I don't know if I need to remove the gear cassette. Even then, I need guidance in taking it apart.

Appreciate any suggestions and/or the file referenced here.

Thank you,

Baris.

The clicking noise is likely external to the motor. The motors are almost bullet proof. The clicking noise can be a caused be a broken spoke or a broken axial. Carefully check the tension on each spoke. To check the axial you will have to remove the cassette. I don't have a procedure, but it similar to a standard bike. Good Luck.

Wow spokes it was indeed!. So simple.. About 8-9 of them were loose, and problem went away instantly. Thank you so much for the suggestion.
