| Abstract: | A new type of AC-AC generator-motor set is presented.In this paper,the first method is that the speed of the multi-speed induction motor of economizing on electricity can be changed step by step and the second method is that the frequency or voltage of the diesel engine generator can be controlled smoothly.Com- bining the two methods mentioned,we get the result to increase the speed ratio of the generator-motor set.In addition,the main controlling theory and the torque-speed characteristics are explained. |
