| Abstract: | The technology of electromagnetically variable speed and its basic principle were introduced. The capability of electromotor, the dynamic characteristics of electromagnetically variable speed drive and the system controlled by computers were studied. The control arithmetic of excavator with electromagnetically variable speed was presented, and the control arithmetic was achieved based on PLC. The experimental results indicate that electromotor has the characteristics of low malfunction coefficient, simple maintenance, variable speed performance and low costing, and can be used in the worst environment, and so on. |
