The development of generator technology continues to improve from year to year. The scope of such improvement varies from the shape, design, size, the usage of material, and even regarding to the efficiency of the generator output power. However, the role of the software to design such electric machinery in the improvement of generator technology development should not be ignored. So before designing and manufacturing the electric machines, especially generators, it is important to know the specifications of materials which are needed in the design of the generator, regarding the initialization of each constituent part of the generator for example, in the pre-design process of a 12 slot 8 pole generator is a must.
