Main Question or Discussion Point
Hello
I'm working on a project which requires a rotating platform.
I'm planning on turning the platform using a stepper motor,
however I'm sure how to calculate the torque required to move
the load.
Here is what I have:
the moment of inertial for the load and platform is: 2700 oz in^{2}
the platform must turn 30 degrees in 2 seconds ( have a angular velocity of 0.2618 rad/s)
the motor is directly attached to the platform (no pulleys or gears)
I tried calculating the torque using the method in the pictures.
The torque I got seems too large to move a load which weights 5 lb. Perhaps I should have used the step angle, or maybe the formula I used does not apply to this problem.
Could someone help I would very much appropriate it. Thank you in advance.
