Thx for your input,
Sure I could kust test it, but I need to know how this will behave in time. That display is gonna be installed far away from me and I want to avoid maintenance overthere.
For this first occurence I m going to hang around 500g on the shaft... But I d love to design something more versatile and be able to hang object as heavy as 1Kg in the future without replanning a design with a gear system.
If you think the motor can't handle this (500 to 1000g), I'll directly make a design with a gear to avoid loading the motor. But If its not needed...
