Good day everyone :)
I am an undergraduate student working on a project involving the use of high torque small-sized DC motors for use in designing a person following trolley bag. Where in the problem is to use small sized motors but still maintain the usability and efficiency in carrying loaded luggages.
I have been looking for motors in local stores as well as in RS components as well as Element 14. However I am not sure if my choices are the right fit as I am at a loss on what specifications to look for when selecting a particular motor for this application. I have also tried to look for motors used in current products that can be used in my application such as todays electric skate boards but unfortunately have no luck on finding their suppliers.
Basically the question I would like to ask is what specifications or calculations can I perform to select the proper motors given size constraints and weight carrying requirments. Or does anyone have suggestions on common motors that are already normally used for this application. My target maximum load capacity is 20kg.
