Electrical Machines In a dc generator operating on load with its brushes on the geometrical neutral axis (GNA), the magnetic neutral axis (MNA) is shifted in the direction of rotation. Now, if the brushes are given a lead of 90° (electrical), then the MNA will shift forward by more than 90° shift forward by less than 90° shift forward by 90° coincide with the GNA shift forward by more than 90° shift forward by less than 90° shift forward by 90° coincide with the GNA ANSWER DOWNLOAD EXAMIANS APP
