Me and another person were rummaging through one of my colleges labs looking for usable parts for my groups product design course. We found this medium size motor that weighed about 2-3 pounds. The problem is that there were no stickers at all that indicated its specifications. There were a few numerical engravings, but without words it was hopeless. We hooked it up to a 12 V power source and it powered up fine. Does anyone know of an easy apparatus we can set up to test for its specifications? Maybe hook it up to an arm and having the arm depress a scale?
