There are quite a few early attributes of the phrase. Like all things these
days it gets attributed to someone on the Internet and sticks regardless of the
truth. I guess we need to find the actual writings to verify. I have read
(nearly) everything Hemingway has written and I don’t recall i

Minor nit? No. Sorry, our good and well known sci-fi author Robert A.
Heinlein borrowed it from Hemingway, Hemingway was first to use it
Minor nit: " The E. Hemingway phrase TANSTAAFL: should be "The Robert
Heinlein phrase TANSTAAFL".

NP Nicklas, I just want to emphasize that we were looking at different
pages and user experiences. I bel
Oh i didn't think about stepper. The equations are useful for DC, BLDC, PMSM,
Asyncronous and probably also for switched reluctance.

Motor torque depends on current. Then increasing acceleration torque will also
increase but how much depends on the inertia, there rotational inertia and the
mass moved. It is also possible there are some viscous load which depend on
speed of motion or rotational load. I assume current will incr

Increase in speed should almost certainly be 48/28 faster. I think this is true
for acceleration to. Then you just have to hope for the electric motor to
tolerate the higher voltage and for the mechanics to tolerate higher
speed/acceleration.

Greetings;
I am in the midst of replacing the 28 volt motor supply on my mill with a
48 volt contraption.
This should, all other things remaining equal, allow me to make my accel
setting a little faster, and the MAX_VEL's a bunch faster.
Since I am going from 28 volts to 48 volts, is there a "
