Drive Size: Ratio of Inertia's
Drive Size: Ratio of Inertia's
(OP)
I am trying to size an AC or DC servo motor. Some manufacturers recommend the reflected load inertia not be 10x greater than the rotor inertia, while others do not mention it at all. Is it necessary to have this restriction? Continuous torque is ~10 in.lb and starting torque is ~20 in.lb. Drive reverses every 5-10 seconds.

I can meet the 1st two requirements but the 3rd is making the motor too large dimensionally. If I meet the 3rd requirement, I have way too much torque.
I'm wondering if I have enough torque to accel/decel the load, why do I need to worry about the ratio of inertias?
