On the curveness of magnets

Posted on December 28, 2007


To better illustrate the problem of using flat magnets in a radial design, here’s a couple of pictures.

One: a big single magnet with 40mm width.


Two: a set of 4 smaller magnets with 10mm width.


Clearly the mechanical adjustment is better with multiple magnets per pole.  It is easier to glue, and the resulting air gaps are a lot smaller.

Questions? 🙂
