| 摘 要： | 本文用等效模型对异步电动机能耗制动状态作较全面的理论分析。把能耗制动时的异步电动机等效为一个正常三相交流励磁的异步电动机。得到等效模型。通过对等效模型的分析,自然地把能耗制动纳入异步电动机的四个象限运行。较完整地得出:处在能耗制动时,异步电动机特有的等值电路、相量图及机械特性。

| Abstract: | The induction motor in D.C.injection braking state is theoretically analysed and the equivalent model is given in the paper.In the discussion,we consider the braked induction motor as one which was normally excited in three phases,so the moton can be studied in the four quadrant operation.The equivalent circuit, the phase diagram as well as the torque-speed characteristic in the braking state are obtained. |
