1 cycle of alternating existing is manufactured each time a set of subject poles passes in excess of a point about the stationary winding. The relation amongst speed and frequency is N = a hundred and twenty file / P displaystyle N=120f/P

Thrust the brushes down against their springs, and insert your "stick" through the holes in the brush holder to help keep them down In the brush holder.
