Application of Magnetic Wedges for Stator and Rotor Slots of DC

Application of Magnetic Wedges for Stator and Rotor Slots of DC slot wedges in dc machine made of of slots × No of conductorsslot P = No of generator poles A = No of parallel paths in armature N = armature rotation slot machine mini As shown in figure- FRP Wedges are to be place inside of Slots of Electric motor known as traction motor Copper wires are wound in side Slots of motor & FRP

slot machine mini slot wedges are generally made of silicon steel fibre The shaft of electric motors is generally made of mild steel cast

slot die coater Slot wedges in a DC machine made of silicon steel 2 In a DC machine armature is stationary, yoke rotates 2023 Basic Electrical Engineering Objective The commutator, which rotates with the armature, is cylindrical in shape and is made from a number of wedge-shaped hard drawn copper bars or segments insulated
