Hello,
I have an idea but i may need some help from GERMAN engineering.
In the photo you can see the pulley looking similar to the one i ordered. The one i ordered will be 19,035 mm diameter in the center where the belt will be because my Scheu is not 300 but 360 mm.
The height of the pulley will be 1inch= 25,4 mm. Weight will be around 18 grams .
I was thinking about asking Sota to make the lower ( first 5 mm?) part bigger in diameter .Let us say 40 to 50 mm.
I can also add an aluminium or edelstahl ( about 2.8 times heavier) ring myself to the pulley. The motorachse is 6.35 mm so i can make an aluminium ring with a 6.4 mm hole in the center with my GERMAN Trumpf t500. With no other holes such a ring would be around 10,5 grams with 50 mm diameter and 2 mm thickness. As you can it is easy for me to add one or more circles with holes at equal distance so most of the mass of the ring will be on the outside. THEN the flywheel effect will be bigger.
That is why i asked Thomas Scheu to make my platter this way. Up 360mm and down 400 mm so i can still use standard length arms.................
Making the 2 mm ring myself i can create more flywheel effect because it will allow me to put more mass at a greater distance from the motorachse.
The motor will turn 600 rounds per minute.
The complete Sota unit checks the speed of the teller every round the teller makes so every 1,818 seconds ( 33). Then it will slowly adjust the speed before 'he next turn starts"''
IF the electronics are programmed to adjust the speed very quickly it will probably not work because the effect of the flywheel will be that it will not allow to make a quick change. AND it will also be difficult to make a quick change because the 12,6 kilo, 400 mm will resist a speed change too.
I decided to ask German people because they live in an engineering country.
Will adding a ring ( with the numbers of holes i think about it will be maybe just 5 to 8 gram) aluminium give me benefits? The biggest ring i can make on my German machine will be 60 mm. BUT i have to take care the mass is equally distributed as possible.
My pulley has already a bigger diameter than the original one made for 300 mm teller. I forgot how to calculate the flywheel effect but i think adding a 50 mm ring as described above will increase the weight with 50% . Most of the added weight of the ring will be outside the 19 mm diameter of the pulley so it could well be that flywheel effect will go up more than 50%.
Will the extra flywheel effect be bad for the '' motorlager ''?
If it will start making noises after one year it will not be a good idea.
The electronics in the package will make the motor start with 5 rounds per minute so the belt will have a much long life and i think it will also be good for motor life.

P.s answer in German no problem but i cannot write German, reading is ok
