Slip Ring Wound Rotor Winding

Rotor Winding Process



 
   Removing  rotor end rings from old rotor shaft



    Staggering and cleaning of rotor stampings

 
     Inserting rotor Cleaned stamping and  re staggering them  into rotor shaft

 
   Pressing of stamping over rotor using hydraulic press and special clamping arrangement



   Copper bars of rotor winding in shape ready for inserting

 
    
    Winding in in progress



    Making Insulation between end circuit joints

    

   Connection are made and resin glass binding is carried out on overhang portion of winding.
