1.	What Are The Functions Of Yoke? What Is The Choice Material For The Yoke?
Answer» It serves the purpose of outer most cover of the dc machine. so that the insulating material get protected from the harmful atmospheric environmental like noise, DUST and various GASES like SO2, acidic fumes etc. It provides mechanical support to the poles. It forms a part of the magnetic circuit. It provides a path of low reluctance for magnetic flux. It is PREPARED by using cast iron. For large machines, rolled steel, cast steel, silicon steel is USED which provides HIGH permeability.
