How far apart are they to be to output a good quadrature signal?
Mounting them with JBKwik weld seems to be a lot less forgiving because
its not possible to move them a few thou to fine tune like it was when
using relatively flexible goop.
Well, one sensor should be centered right on a tooth, and
the other should be 1/4 of the way off
a tooth. The best way to check the phase alignment is to
put a 2-channel scope on it and spin the
spindle. If you don't like it, then adjust and try again.
That's how I did it. First, I was dumb and
put one sensor on the tooth and one on the valley. After
MANY minutes of confusion, I realized that
was NOT what quadrature meant!
