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.
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.
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.
