Hi guys, here’s a slightly different photo than the prototype one for the update. @Hummie, despite the transparent plastic (which serves another purpose), that was actually a fully functioning stator.
Kilian didn’t just say “it’s a hub motor, so it spins better than belt drives” like cogging isn’t a thing. He went one step further and reduced the gap between the stator teeth ends to almost nothing. So how did he get those fat energy efficient windings onto the armature? Look closely, and you’ll find the answer.
