Hello Guys

Could you please suggest a stepper motor to rotate a load of 2kg.

Brumby:
What is the size and shape of the load?  Is the mass evenly distributed?  How many steps do you want per revolution and what is the fastest step movement you want to achieve?

I'm not up into steppers of that capability - but that looks like a big challenge.  Because of the (suggested) shape, the inertia would be significant and the acceleration and deceleration you would normally associate with a stepper would translate into rather large forces.

Edit:
You will need a good controller and properly tweaked settings - but that is true for most any stepper application.

jismal:
Mass is an evenly distributed.like a flywheel.1.8degree would be fine. Fastest movent will be around 10 revolution per minute.

beanflying:
Providing it is in a fairly steady state (not accelerating or decelerating) a garden variety nema 17 should be fine but maybe consider an outboard bearing or supported shaft if your load isn't horizontal. So if as shown vertically run an extra bearing  :)

Thanks you
