These all are the preparation of electromagnetic design of synchronous motor. Electrical motor design is a complex process which needs to consider size, data and many other factors . Therefore, we should have a comprehensive looking of the issue and according to conditions, make different situation-specific solutions. In this three options of the design, under the condition of efficiency, depending on the design objectives designs a most light-weight lest materials synchronous generator and a saving energy most synchronous generator with maximum efficiency . After the design I have found that the most provincial motor mostly dose not hvae the maximum efficient and the maximum efficient motor use the most materials. Therefore, in the actual design the motor must have comprehensive consideration so the the optimal programme not only use fewer material but also have a relatively high efficiency . In addition, this article makes a presentation and overview.using of rendering graphics software AUTOCAD and computer programming-aided design
