Tesla Model 3 Powertrain (BLDC Motor)

Nice project, but Honestly, it has NOTHING to do with Tesla. Every EV, actually, nearly every device has BLDC Motors today

That's what I actually thought at first, but it turns out the EV1, the Chevy Volt/Bolt, the Nissan LEAF, and the Tesla Roadster 1, Model X and Model S all have Three Phase AC Induction motors. Tesla wrote a blog post about their choice of 3-phase induction motors when they were designing the original roadster, and I was surprised when I learned that the Model 3 would be using BLDCs.

From what I found, I think the most common electric motors are actually still Single Phase AC induction motors (in devices like table saws and drills) and 3 Phase AC induction motors (in most EVs and PHEVs)

It seems you found very old, very outdated info, first hybrid car (toyota prius) was using 2 BLDC motors back in 1995, and toyota use them since now in all hybrids, only home made construction often don't use them now. 3 phase AC induction motors were used long long time ago when neodymium magnet price was insane so there was no other option. Realy your thing has nothing specific to tesla and it looks like keyword search manipulation.

The prius has always had BLDC's. The Tesla M3 is the first fully electric car to have BLDC's. Neodymium magnet price is not the limiting factor, it is rather that they are a pain in the ass to manipulate. I know from experience. I killed my computer making this motor. As stated in one of Tesla's early blogposts, Tesla would use 3 Phase AC Induction Motors to reduce manufacturing costs, and every single fully electric production vehicle until now has used 3PACIM's. Although Toyota has always used BLDC's, Tesla, GM, and Nissan have always used 3PACIM's. Rimac Concept One, Neo EP 9, Formula E cars, Tesla M3, and the Tesla Semi are the only fully electric cars I have encountered that use BLDC's.
*This surprised me when I first found out. It seems like BLDC's are more simple and more powerful for their size, and while they are better in some aspects, they are more difficult to mass produce.
**Yes, I am slightly manipulating the tags, but if an improper tag leads to more people doing research and learning something surprising, I don't really care. I'm only getting about 50 more views per month since I changed the name, and I don't actually benefit from getting more views...

Hi guys, I promise I actually did build this and it did work. If you're having problems, leave a comment or message me and I will try to respond within 24 hours, but I am a student and I have a busy life.

I am also planning on building a bigger version of this, which I plan to electric-swap my own car with, but that might take another decade* to come out because it will be expensive and likely take me over a year to build.

*Edit: Changing the time frame for the new motor. :) (Previously Said "another year")

Also, check out my smaller electric motor. It uses most of the same materials, but does not require an Arduino controller to run. http://www.thingiverse.com/thing:2069422/
