So I have a Gr 11 Physics Science project. I need to build a Brushed DC motor.
I already build an armature with coils. I have a copper commutator and copper are connected to it. Lastly, I placed electric tape on the wood body
The problem is that I don't know how to make an effective Brush Motor. I tried sheering a copper wire and using the end of it as a brush, but it had too much resistance.
I also tried 2 copper sheets but that had even more resistance. Someone please help!
