Motor-Gear box selection - Help

[nkviswan]

Hi,

Is there any classic calculations to determine a motor-gearbox combination based on the output load characterstics?
My application :
Design on an EOAT - Payload 600 kg, motor-gearbox needed to provide the EOAT a rotary movement of 90Deg. This is the input details I have.
Can you please suggest me how to proceed from this point?
It would be of great help.

Thanks in advance,
VJ

What amount of acceleration do you need? What is the axis of rotation? (horizontal or vertical) How far from the center of rotation is the center of mass?
