摘　　要：建立基于空间矢量坐标系的动态数学模型,研究相控调压技术下感应电机的能耗变化。并通过M AT L A B仿真得到电机在不同触发角下的各项损耗变化趋势,特别是定、转子铜损耗和铁损耗。实验数据验证了仿真结果的正确性。The dynamic mathematic model based upon space vector coordinate system was established to study the change of energy loss of the induction motor under phase-control AC voltage regulation. Change intension of various loss of the motor under different firing angle was achieved by means of MATLAB simulation, especially the copper loss of the stator and rotor as well as the iron loss. Data of experiments verified correctness of the simulation results.
