(C) no of equalizer rings used 2Z/P, purpose of equalizer rings is to equalise the current in each parellel path

1 Answer

Answer :

Equaliser rings in dc machine is 

   Current flowing in machines to share equally during parcel operation of dc machines 

  In case of Equaliser rings are not connected to machine the load sharing is not satisfactory because the current sharing between two machines flowing not equally

    Equaliser rings are use series and compound motors only
