Hello
I want know if i can command a steeper motor (torque 5NM) with an arduino UNO and who i can choose my driver?
Maybe 5Nm is to much for an arduino? must i use for exemple a reducer and use a little motor?
Can someone answer me please?? thanks alot !
Hello,
I want use a steeper motor to rotate a cube along an axis (5NM), Can i command a motor 5NM with an arduino NANO, and who i must choose my driver ?
I found a steeper motor (torque 5NM, V=110V, I=6A..!!) must i choose a little motor and use a reducer to have 5NM??
Thanks a lot for your answer !

Of course. All the UNO needs to do it tell the stepper driver to step and fetch.
who i can choose my driver?
Well, since you have said nothing about the voltage of the motor, or how much current it needs, only you can.
Maybe 5Nm is to much for an arduino?
The amount of torque is completely irrelevant. All the Arduino needs to supply is enough current to trigger the step pin on the stepper driver, which is hardly any.
must i use for exemple a reducer and use a little motor?
For what?

Just this once, since you asked so nice. Even though you used more punctuation than was needed!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

in fact i fount a steeper motor how have (5NM) but V=110V and I=6A, that's why i though to use a motor who have (0.1NM V=24V and I=2A ) with a reducer to go up to 5NM because I don't know if i can command with arduino despite these value of V=110 and I=6 ?
The Arduino is just going to tell the stepper motor driver to step. It does not matter whether the stepper motor that the driver drives is 1V DC, 110V AC, or 440V 3 phase AC. It does not matter whether the stepper motor needs 0.1A or 10000A. The Arduino is NOT providing the voltage or the current.
Ok tanks, so any driver Who can aliment the motor with 110v and 6A can command it!
Hello and welcome,
Can i command a motor 5NM with an arduino NANO
YES - the NANO just controls the motor driver
and who i must choose my driver ?
Good question - let's go to that point when we know a bit more about your configuration and if you will need to drive the motor directly (then you need a big driver with big power supply) or if you can go with a gear driven motor, then you can go with a smaller driver and motor.
Perhaps if you describe what you are trying to do, we can work out if this is the xyproblem again.
Perhaps a stepper motor isn't what you need, but you don't say what you are doing.
You will need an industrial stepper motor driver for that motor. It will cost several hundred US $.

The cube rotation range is -45° to +45°.
That sounds like a job for a servo?
The maximal torque generated by the cube is Cmax = 5 N.m
Please explain how this is derived.
...R
A picture of your set, handsketched is fine, would be helpful
attached a picture of the cube that i want to rotate it, in fact i have nothing for the moment i will make a virtual simulation with ISIS and SOLIDWORKS ...
**But i'm not sure, is the stepper motor the best solution for this application?
**Must i use a motor which has : torque <1NM, V=36V, I=2A with a DC Driver and a reducer to achieve the 5NM ? can this solution be cheaper than an industrial driver ?
**An industrial driver can it be controlled with an arduino ?
So now we know the dimensions of the cube in unknown units...
Perhaps you could give some useful information like the mass and size of the cube in SI units
and justify the 5Nm figure you keep mentioning - a regular cube is balanced and I wouldn't expect
so much torque to be needed. Or are those units inches?
Nm, not NM. The symbol for the newton is 'N', the symbol for the meter or metre is 'm',
in SI 'M' means 10^6
well seen, i don't have the unit but i supposed in mm
i know that the cube generate 5Nm so i can calculate the mass but i think it's not needful if I already know the torque, no?
It's a project and this is the data's i have i don't have more informations.
I need to know if it will be stupid to use a brushless motor, a driver and a reducer instead of the stepper motor
If i must use a stepper motor that generate 5Nm, must i use an industrial driver and an arduino to control it ?

We are having trouble believing that value - it seems far too high. Please provide an explanation of how the number was arrived at. (Second time of asking!)
...R
i don't know the explanation, i have a test and the engineer tel me to make a system to rotate a cube that generate 5Nm
Well ask the engineer for an explanation.
In the world I live in cubes don't generate any torque.
If you have a mass (whether a cube or any other shape) mounted on a shaft it requires a torque force to accelerate the mass from one rotational speed to another. The force will vary widely depending on how quickly the mass is to be accelerated and also on the moment of rotational inertia of the mass. (hope I have my terminology correct)
...R
Moment of inertia scales as square of dimension for constant mass, or 5th power of dimension if
constant density.... Off-axis torque load scales as 1st power or 4th power (constant mass, constant density).
Give us some confidence in the that 5Nm figure please! Those 4th and 5th powers are unforgiving.
If you don't explain what you are really doing the xyproblem nonsense looms... xyproblem.info
ok thanks, Now i'am more confused than before.
I just want to know if who to command a stepper motor which has a torque=5Nm V=110 I=6A with arduino and what driver i must choose.
Thanks for your answers.
