Thanks for eveyones help so far

Bit of both really, protect motor and gears mostly. How do I calculate the start up torque needed? I know that it must be more than the resistance friction but am unsure how to calculate this. It would be starting up on a morning (only once hopefully) and running all day, so that time to...

The decision has been made that we need to have a clutch plate. What I am struggling with is how to calculate the size of motor that we need. It will be a motor with a worm gear that turns three pulleys, each one turning an alumium disk. I need to know how much torque will be needed to get...
