Re: [z_scale] coreless motors
- View SourceDominique
There has been much discussion on this topic (I'm not sure
if it was this list or the Digitrax list). Some people have said that
coreless motors don't run well on pulse power and that they
run hot on pulse power. This has not been my experience
(and others). I run my Rogue engine and a couple of engines
that I have scratch built using Faulhaber 8mm motors on
either pulse DC or DCC (which is PWM DC) without a problem.
I usually run them at a slow speed (which is supposted to be the
worst for coreless motors on pulse power) for hours at a time
without overheating or any other problems. Some of the
technical people on the list explained that all coreless motors
aren't the same.
