【正文】 iency, temperature, etc., in the program a second program is based on the reselect the data to synchronize generator efficiency and optimum temperature, and finally a set of programs is based on the program two synchronous generators think of ways to make the most economical use of materials. After the design was found: a province of the material the most efficient and the motor is often not the most efficient material used motor is the highest. Therefore, the actual motor design must take care of, considering, and finally get a material is both optimal and efficient program. At the same time control loop design. Through these three programs, made me a better understanding of the synchronous motor design steps and methods, while the application of CAD software, graphics and other details of operation of a range of more skilled. Keywords: synchronous motor, design, CAD, frequency control, control loop 目錄 目 錄 摘要 ...............................................................................................................................
