Why the Newman torque is low and what to do about it

[kmarinas86]

It seems that most of the designs of Newman motors I have seen have have coil walls that are many times as tall as they are thick.  But the software program I used to see what would be the optimal coil, in terms of getting a high inductance for a short coil of lower mass, were coils whose walls were about 6 parts tall to 5 parts thick (or sometimes 9 parts tall and 8 parts thick).   The Newman machine replica I made (http://www.youtube.com/watch?v=2FNTTyGjs04) had a coil ratio similar to the one considered optimal by the software program I used (http://www.datavoyage.com/coilmaestro/).

For
Inductance L = 0.405 mH or L = 0.404 mH
a = height of coil
r = width of the coil wall
d = wire diameter
O = wire length
W = wire weight

OPTIMAL
N = 114
D0 = 24.0 mm
a = 9.0 mm
r = 8.1 mm
d = 0.8 mm
L = 0.405 mH
O = 11.50 m
W = 51.6 g
R = 0.4 Ohm
--------------------
SUB-OPTIMAL
N = 149
D0 = 22.0 mm
a = 20.0 mm
r = 4.8 mm
d = 0.8 mm
L = 0.404 mH
O = 12.53 m
W = 56.2 g
R = 0.4 Ohm
--------------------
TYPICAL NEWMAN MACHINE FOUND ONLINE
N = 187
D0 = 23.0 mm
a = 40.0 mm
r = 3.0 mm
d = 0.8 mm
L = 0.406 mH
O = 15.27 m
W = 68.5 g
R = 0.5 Ohm
--------------------
TYPICAL NEWMAN MACHINE FOUND ONLINE
N = 222
D0 = 23.0 mm
a = 60.0 mm
r = 2.4 mm
d = 0.8 mm
L = 0.405 mH
O = 17.69 m
W = 79.3 g
R = 0.6 Ohm
--------------------

Now, a major problem with the larger Newman machines is the special commutator you need to even move the thing, because the current is so low.  The alternative, say for a medium size machine or better, would be to maximize the inductance for the coil used.  Now, this would mean a higher wire to magnet ratio.  But it also would mean a magnet with more specific torque.

0.6 ohm?
what ar u talking about its 10/20 ohm or more on a typical newman motor coil

stop giving people the impression that u no a lot because u don't u "quote" text  and copy and past.
on your you tube site u delete all comments of people that try to make a debate.
and the most irritant thing is u don't answer but u just go over it wit your long talks of BULLSHIT Sad Huh

pleas stop this sick madness






i am sorry fore the rest of the people of this forum that i have to say this here.
but on his You tube site its not possible if u ask him something that he he don't no he WILL delete the commend.

There is no debate possible wit this gay he even don't no how a transistor works
but he will be the 1e! to put a comment on adder you tube users that made a Newman motor.
but its not really a commend because it really don't add any important info its just BLABLA

1 time i hat to delete more then 5 comment of him because u can't see anymore the real comments of older people
if there was a limit of 10.0000 letters he will use all of it  to just QUOTE his bullshit

I am sorry. When I said "TYPICAL NEWMAN MACHINE FOUND ONLINE", that was misleading. What I should have really said was that

"a = 60.0 mm
r = 2.4 mm"

Where "a" is the length of the coil and "r" is the thickness of the coil, corresponds to the fact that in many Newman motors, the coil is longer than it is thick.  This post I made last year, in fact, not even a month after I started making these "Newman motors" (which are not actually real Newman motors). Anyway, glad that is over with.

You misoverestimated how often I delete other people's comments.  In fact, most of the comments I delete are mine since I later find I have misjudged what the person said, or decided that I could give a  better response.

And please do not refer to giving "thumbs down" to comments as deleting the comments.  They are not the same.  But I must admit that I still acted wrong.  See to it that I do not do this again on these videos.
