Re: [TCML] Salient Pole Query

Phil,

I don't know the answer to that, but my guess
is that no difference could be detected.  The
whole process doesn't seem to be all that critical
as far as I can tell.  Various folks have tried various
widths from 3/4" to 1" or so, and everything seemed
to work fine.  possibly the motors ran a little cooler
at 3/4" width (assuming a 3" dia rotor).

Hello.

Well thanks for such prompt replies everyone. I had already picked up 
your
website from the archives John, and was already planning on building 
your
circuit. In the web article it is mentioned to make the width of the 
flats
equal to the measurement from the midpoint of one pole [that's adjacent 
to
the 'dead' one] to the corresponding midpoint  of the pole on the other
side.

Taking your 'quarter width' policy onboard, if I measure my rotor's 
diameter
is there any point in 'adjusting' this figure slightly [up or down in 
size]
so that its final width bears a direct relationship to my own poles 
spacing?


E.G. if 3 poles measure 1 inch midpoint to midpoint, and a quarter 
diameter
flat would turn out to be 0.9 inch, is it better to make the flat 0.1 
inch
wider at 1 inch.

I know it's no extra work but is there any gain?



Regards



Phil
