1. The problem statement, all variables and given/known data Hey, For one of our final lab projects, we have to (less design and more build) an electric DC motor on a 6V DC battery. Restrictions/Requirements: No plastic parts can be used The motor must run for at least 60 seconds No simple motors allowed "not-simple" means, it must have brushes and a commutator. 2. Relevant equations 3. The attempt at a solution I know the physics behind it, but I'm having trouble building it. What would be good material for the armature? And do I wrap the coil around the armature and then wrap it around the axle? Any tips or resources on this would be helpful, thanks in advance.
