That isnât a noob question.
That is a very complex, multi opinion, big variable, math depending Shart qustion

I personally use onshape, it requires an internet connection since it is a web browser based tool (they made extensive use of WebGL to build CAD in the browser no download or install required). I went with this because Iâm always changing machines and often OSes and using chrome as the common portal to all my 3D work, works well for me (mobile apps are nice to show things off on phone or tablet too). You can export STLs which are like a bitmap of 3D files just a bunch of points and the edges and faces that define the model (the âworking fileâ in parametric modelling tools is the STEP file which most CAD programs can export or import certain ones will support or not support certain features but this is closer to a PSD or the âworking fileâ), the STL is the output/result that can be sent to anyone to slice of create tool paths to create that shape.

I should note the big downside with onshape is the license is either like $10k a year or your models are all public domain (I opt for the latter, but this could be an issue for people)⌠Excuse all my parenthesis youâd think I was a LISP programmer.

Both Fusion and Solidworks have their high points and low points, but the reality is that you can get Fusion for free as a hobbiest, and you canât do that for solidworks so kinda seals the deal
I have Licenses for Solidworks from my school for now but they probably wonât last long

hehe, No problem!
Thanks for this!
Hope you donât mind me tagging both of you each time, but you guys know everything technology wise

I conducted a highly scientific poll of my girlfriend, asking her âwhat would you say women think of electric skateboards?â and her one word answer was âdweebs.â

Highly impressed.
Honestly i am happy with being only a dweeb, at least i am not a penis warmer or a future shit sheet.
Please thank her and send her our return greetings

Hereâs some more anecdotal data. My girlfriend asked me to build her a esk8 after she saw mine. Now she rides with me.

Pulled my stator out to swap the phase wires for bigger ones, and a couple of the wires were glued to the metal mounting piece and snapped when I took it off, is this going to be a problem?

Might as well rewind. At best the motor is weaker. At worst it could short.

I have no idea how to rewind and donât trust myself. The motor just passed a foc detection with no issues which is great. Whatâs the chance of it shorting?
Letâs put it this way: You now have a V8 engine that is running on six cylinders. Yes it still runs, but not well and itâs only a matter of time before it grenades.
And you donât want to be riding it when it grenades.

It might be fine if those loose strands are kept from shorting.
Makes me wonder how bigger motor companies like Tesla deal w the inevitable degradation of insulation on windings as eventually everything breaks down especially with heat cycling. For us and hobby motors the short could be very serious and across whole phases locking up brakes. If its a short across just a couple of turns on a single tooth that maybe wonât launch you (launcher me) but hobby motors donât take extra measures to avoid phase to phase shorts. Bet Tesla further isolates anything that told be disaster if shorts. Iâm imagining a wheel locking up in a highway.
Another danger being the heat of the motor increasing inductance and resistance to the point the esc looses sync. Inefficient on the way there and then bam.

Sweet looks like Iâll be rewinding it. Any tutorials to help me through this process?
Itâs easy. If u can fit an LRK winding even easier. But my talk of dangers isnât really ur motor and if u insulated and pinned that loose one or two little bits and u pass the foc probably as safe as the rest
Just search LRK winding. And make sure u remember starts and ends of phases and clockwise and counter. Thereâs a lot of little things to worry about but nothing complicated. Strip it without taking off the insulation on the stator is maybe most important otherwise the new winding will short. Heat the stator hot and pry it off but sure not to pull off the top r bottom lams. Rewind and u need to epoxy it. A lot of doing maybe just fix n go.
If u have the original bldc results: resistance and inductance. âŚand you do rewindâŚbe nice to see how it compares. These hobby motors are low quality considering what u could get in the same volume. The winding is one side easily improved. The rotor side also can be hugely boosted if you get the mags our w acetone and glue them back in with thin magnets sideways between (hallbach). A lot of these motors are w maybe 80% magnet fill which is good for a high speed motor but we want high torque and low copper losses mostly and 100% fill is better. With the hallbach way better as the iron behind them is so thin being designed for planes and the hallbach catches the otherwise lost field of the mags.

http://www.bavaria-direct.co.za/ has a lot of info and theory, as well as a calculator for finding the ideal winding scheme.
https://www.instructables.com/id/Rewinding-a-Brushless-Motor/ Hereâs a pretty concise walkthrough of the rewinding process.
Something you will have to figure out (I know thereâs a calculator around somewhere but it escapes me at the moment) is finding the ideal number of wires - You want to have the desired number of turns to achieve the expected KV, with the lowest possible resistance - And thus the most copper you can pack into the stator as possible. More copper means less resistance and thus less energy wasted as heat.
There are lots of other resources out there, just search for ârewinding BLDC motorâ or similar.
