Reducing inertia impact

[aand74]

We have a servomotor with gearbox (i=+-20) driving a big steel disc. This disc has a high inertia.
Are there mechanical compensation methods for the inertia of the disc? I know motor and gearbox have to be right sized, but I want to know what you can do strictly on the mechanical side to reduce inertia of the load that is seen by the gearbox.
Well understand that the disc itself may not be changed at all.

Adjust your acceleration and deceleration rates so that you don't exceed the torque capacity of the gear train.

Gearing is the only real mechanical compensation. You can also get a bigger motor. You can upsize the motor to get a better inertia ratio, but you don't always need to upsize the drive if you don't need the extra torque. Depending on what you are doing with this, 20:1 might be controllable. Gentle moves only, though.

If you are only worried about braking you could add a friction brake? Doesn’t do anything for acceleration.
