Wind Generator Parts Can You Help Me In My Wind Turbine Project?

Can you help me in my Wind Turbine project? - wind generator parts

I decided that a wind turibne for our research project to make. It is my intention, the structure of the brushed DC motor for the generator to follow. In the arms of the rotor, where the contact between the magnet and armature, must be attached to the rotor, the impact is on the brush? The answer to this question would be a great help. Thank you.
