Hello All, I am a newbie here so please be gentle.
I am designing a machine to test vertical applied loads on a sliding table and need help to determine the correct motor size (Torque rating) to handle the load and stop start action.
Essentially it is a linear sliding table using 4x HGH35HA blocks on 2 rails.
It will have 250kg and 900kg vertical loads applied to the table (fixed castor wheel to give rolling motion) as it travels fore and aft.
It will have a 300mm stroke at 50mm/second stroke rate and each 'test' will comprise 1000 cycles/passes.
Approx 25 tests with 250kg and 6 tests with 900kg.
I am planning on using a 3205 single ball screw which is probably an overkill but better safe than sorry.
I am wanting assistance in determining the best sized motor, at this stage I am thinking of Nema52 stepper motor with 50nm torque rating and hybrid stepper driver, is 50nm sufficient or too big.
The machine will probably only conduct 40-50 tests in its entire lifetime.
