Which part of the dynamo requires the greatest attention? Why? . ANSWERS TO QUESTIONS 1. DISCUSSION In this experiment. we are able to determine and to know what the different parts of a dynamo is.Armature winding. Is it possible to use the Revolving Field Stationary Armature construction for DC dynamos? . because of a Dynamo is virtually the heart of the dynamo.Yes 3. Why are some parts of the dynamo made of highly permeable materials and some are made of conductive material? . 2. to understand why some parts of it are made . creating an electric current in the wire.Because the motion of the wire within the magnetic field causes the field to push on the electrons in the metal.GRAPHS AND DRAWINGS Magnetic circuit of a four pole dynamo. armature core. armature windings. I conclude that there is different parts of DC dynamo and generators which every part . is it important inusing a DC dynamo or not. commutator. shaft. We can see that the parts of the dynamo are frame or yoke. brush holder with also brush. CONCLUSION After doing the experiment and complete the data’s needed. After we determine each part of the DC dynamo. what is the function of it.of conductive material while other parts are made of highly permeable materials and lastly to know how motors and generators operate. pigtail and also spring. we identify each of it if the part was a copper. First thing to do is to make a physical inspection of the stator and rotor of a DC dynamo. After that we need to understand and think what the different parts of the dynamo is. Then we will identify each parts of it and take note what material type it is made. poles. field windings. Lastly we need to draw the magnetic circuit of a four pole dynamo. steel orany type of metal or material. JONES Basic Construction and Working of a DC Generator by Kiran Daware . I observed that some parts of dynamo are made of conductive materials much often that made of highly permeable materials. and BYRON M. POTTS.

I can say that motors and generators are machines which convert electrical energy inputs into forces or applied kinetic energy inputs into electrical energy.of it is important for running it. page 11 by C.
