Has any body ever removed ever removed the axel/shaft from the stator of a direct drive hub motor in order to swap it out whith another identical stator? Specificaly I have 2 2015 9c hub motors. An unused front 10x6 hub and a used rear 10x6 hub that has a bad stator. It looks straight forward...

Amberwolf, This is a new post that refers to an old post back on March 2022. You where helping me with my 2014 10x6 9C rear drive direct drive that needed new halls. The wiring had gone bad & blew the halls. Everything you told me was spot on, unfortunately I solderd the halls on the wrong side...

I finally got the pcb's from Aliexpress. (took a month) The boards are identical & the halls physically appear identical. They are all digital bipolar hall-effct senor IC's. The 3 type of halls are: 41F, 413, & 3144. I'm going to use the board with the 41F halls. Grins hall's are a S41. If the...

Thanks. That's kinda of what I thought. I already soldered them using your technique & it worked much better. I did scrape each strand of the coil wire shiny bright. It was a bit of a pain but I think it helped the solder stick. Why is the original wiring (on a 9c DD anyway) twist the wire (like...

Quick question. I bought a box of insulated solder seal butt connectors sometime ago & have never used. Would they work well for connecting the phase wires to the coil wires?

Thank you, Both where very helpful. I use a butane solder iron but I was using the wrong tip. 2nd mistake was when I de-soldered the old wire I left the remaining solder on the coil wire & attempted to wrap the new wire around the old wire w/solder & it looked pretty pad. I use a heavy shrink...

This is great. Thank you so much. I've watched 2 videos on this but although I got the general idea you really couldn't see the details. Also the end result on both videos looked a bit sloppy for my taste. I have to have to redo all of my wiring on this motor cause I replaced my small Z910 9...

Thank you. I looked at those pics off & on for 30 min & could not see that. It's clear now. What I meant about splicing wires was in case I had to go without the pcb. Clearance inside this 9c looks pretty tight. It appears then that the board shown in the 413 & 3144 pics would work even if...

I'm now pretty clear as to how this all works but I'd still like to get a new board or board with halls but I can't seem to find one that is built the same as mine & I've looked at a lot. (I damaged mine & can't re-use it) Below is a good pic of the board on the new/old motor I have. It's very...

When you say flipped you mean the signal side is different than the others? I just ordered some SS41 Hall Sensors from Grin & the page shows the + - & signal. That was a big help. As for 60 versus 120 degrees my board does say 120 & I see the 60 on the screen shot but the measurements including...

All of my halls where bad. To make sure I was testing them correctly (I thought all 3 being bad was odd) I took apart my unused 2014 wheel & they tested exactly as you said they should. Below is a screen shot of the halls & board I think I need. My question again is the order of things. This...

I just re-read your directions & realized you said "turn the magnet 180 degrees.

I was going to ask that question but forgot. You say turn the rotor 180. Does that mean I should have the stator sitting in the field or am I just moving the magnet around the stator 180? Another question and I was going to experiment with this one providing their bad. Is it possible to remove...

Thanks so much. As I started looking closely at some of these boards I realized that the plus & neg. where marked and as some of these had wires attached (even though they have to de-soldered) the signal wires where actually in the correct order. And speaking of fitting through the axel hole...

I rewired my 2014 9c motor cause the insulation had gone bad on 1 of the phase wires & 2 or 3 of the signal wires. This motor had always run great until it didn't. I bench tested it today using a spare controller & throttle & got nothin. Apparently the bad wiring caused 1 or more of the hall...
