Thanks to https://www.PCBWay.com/?from=atomic for supplying the PCBs used in this video.
We're getting somewhere with the PCB motor - it spins pretty fast - but we're more interested in torque. There's been an interesting question from the viewers - why use a wedge-shaped coil? Surely a spiral coil is better.
Let's try and answer this question with a bit of science!

感谢 https://www.PCBWay.com/?from=atomic 提供本视频中使用的PCB。
我们的PCB电机有了一些进展 - 它旋转得相当快 - 但我们更感兴趣的是扭矩。观众们提出了一个有趣的问题 - 为什么使用楔形线圈？螺旋线圈不是更好吗？
让我们用一点科学知识来回答这个问题！
0:00 我们为什么在这里？
1:13 为什么不直接使用螺旋 - 直观的解释
