RE: Pulse Width Modulation a Speed Equalizer(4): Theory at the bench

Introducing new technology always leads to function creep.

Just keep to your original build until you have it working.

Then you can sit down and assess all of the other potentials and determine which are worth the time and effort to implement.

Hi Sean,

Maybe it's unnecessary, although a future luxury add-on could be an encoder, and then the speed can be controlled down to (say) very slow settings, with no motor stalls. I don't know if that's needed or not, or even if such a thing is possible to retrofit to train motors.
