Stepper motor Dyno build log

Hello all,



I've been trying to stress the importance of choosing the right stepper
motor for the job for years now. This runs contrary to the
'bigger-is-better' idea that is so popular among hobbyist. I often point
folks toward stepper motor torque curves but as these are all done by
different manufacturers, with different stepper drives, etc it makes it hard
to try and compare two different motors. (And sometimes I'm not sure how
accurate some of these torque curves are.)

In an effort to have more reliable data to work with I decided to build my
own stepper motor dyno for testing. I just posted the first blog entry
yesterday and another one this morning that covers the build:

and let me know what you think.
