I have recently learned that in order to vary torque output from a DC motor, I need to vary the input current.
A project I am working on requires that I have a DC motor that will be backdriven while providing resistance to a lever. A max torque of about 10 lbft will be provided from the lever. (that's about a 1.5 factor of safety)
Do any of you know of a safe way of varying current to a DC motor for this purpose? Can it be accomplished with an arduino? Would this just fry the DC motor being backdriven?
Any information is appreciated.
