The motor of the Shredder

Hi everyone, my name is Andres, I´m from Argentina. I want to build the shredder so then I can make material for 3D printers (using the other machine too). I want to know how many HP will need the motor to operate correctly. Sorry for my bad english, i¨m working on it too. Thanks

there is a guide exactly on that

(Almost) Definitive guide on Motors (WIP)

I’ve got a monophasic motor 1.1 Kw, gearbox output at 70 rpm and 68 Nm.
It’s slow and unfortunately it clogs (se bloquea) from time to time. But I’m not sure if it’s the motor or in the way it is built.
