| Abstract: | Modelica was used to model a squirrel-cage asynchronous machine and constant voltage-frequency ratio control mode,and a whole model was structured to simulate variable frequency starting of the asynchronous machine,to gain wave forms of several relevant variables.Then the two different starting modes were compared and the differences of starting current and torque under the two modes were also analysed. |

| Keywords: | Modelica asynchronous machine variable frequency starting current |
