Making sense of toroidal winding machine technology
If you've ever looked inside a power transformer and wondered how those tight wire coils get wrapped around a donut-shaped core, you're looking at the work of a toroidal winding machine. It's one of those incredibly specific pieces of engineering that most people never think about, yet it's basically the reason your laptop charger doesn't overheat and your audio equipment doesn't buzz like a hive of angry bees. These machines tackle a geometric problem that would drive most people crazy if they had to do it by hand: wrapping wire through a hole that keeps getting smaller as you work. ...
