I would argue like this:
1 electric motor catalog or producer sites maybe find some applications to choose engines.
2 to think that an electric motor will certainly turn at a much higher speed (sometimes that required) then a system to reduce the turns you have to find it (to pair pulleys, gearboxes, inverters)
3 know that the power is p=m*w (pair * angular speed) and then see your engine size you need, of course you have to consider all the factors you eat power (service factors, frictions, returns) things you find on the catalogs.
4 for the gearbox itself, see producer sites and also find technical guides of choice
5 to think that the process of choice is iterative, that is, make a choice and verify and then add if things are not going. Maybe as first you see if you have gearboxes or engines available as a first attempt.
don't get discouraged if you look on google opens a world

help me!

follow the steps of my course!

maybe if you start from a motor and a reducer next to what I suggested then you play with the roller diameters. However you are coming to cost a lot of design:finger:

the transmission ratio is the ratio between the number of turns or between the speeds and reverse for couples. engines and gearboxes... Ab engines and bonfiglioli gearboxes for example...see that there is. Anyway, we gave it to you.

if you can't continue to be more specific with the questions. :finger:

as you have recommended I have taken catalogs but do not help me at all
how do you choose the engine to use and its gearbox? ? ?
I have a certain pair c2, power kw2 and number of turns n2 and I have to evaluate (upstream of a gearbox freely chosen by me i=I choose it myself) the motor to use then kw1, possibly 4 poles asynchrono triphase.

I just don't know how to be clearer

I wonder if you read all the messages.
you are continuing to repeat the same question by changing only the values at stake (now we have reached an absorbed power of 2kw starting from one of 3 watts).
answers you have had and also corrections of your calculations. the accounts are those, you had already done everything; compares the data obtained with the values shown in the catalog tables and the motorization is beautiful that choice.
a 4 pole makes 1400 rpm (approximately, in the catalog is written), choose a reducer that leads you to have the rotation desired to the drum of the tape. Obviously there will not be your very precise ratio and if you do not predict adjustment systems (inverters, variators etc.) you will adjust the diameter of the drum to the need.
the ratio of the reducer will reduce the necessary torque (and power) in the input (but also this you had already seen and calculated).
I don't know the type of service of that tape, but if you want to stay safe choose a 50% more than your computing power (you can search on the net, and on the catalogs, various service and safety factors).
verify that reducer and motor are of compatible size, indeed, better if you choose directly a "preassembled motor" (all always from catalog, you find all the data... http://www.bonfiglioli.it Register to mosaic and make the configurations completely with downloadable 3ds).

There's everything on the catalogs. If you look at bonfiglioli for example you can mount 0.18 kw and 0.37 kw engines with vf30 and vf 44 gearbox. clearly are two sizes of different gearboxes. in the catalog take the section you need for example vf44 choose the data ones (7 - 10 - 14 - 20 - 28 etc) and next you have the solutions to 2880/1400/900/500 rpm.

However if you use its configurator do before and above all do not choose the features wrongly. then if you look in the first pages of the manuals of gearboxes there are formulas of how you calculate the various characteristics and possible forces on the tree (x some applications).

from your calculations take a motor with higher power. more so I don't know what to say, I repeat... do 4 accounts on my model and you will see that it brings a house and in the end the costs are always those....that use a vf33 or vf44 changes little... idem engines 0.18 or 0.37 kw.

and see you

I don't understand the "delusion." but what would you want more?

rather,
What happened to mitnick? ?

It's out.... you know with the heat...:finger:
