For the first time , the transient simulation of rotor bar subsequent - breaking fault has been completed successfully . also , the corresponding experiments have been carried out . moreover , this paper systematically generalizes the rotor bar breaking fault features , and draws quite a few creative and interesting conclusions 2 .对笼型异步电动机转子断条故障特征做了机理分析,以笼型异步电动机多回路数学模型为基础,首次完成了转子导条持续断裂故障的暂态仿真,同时对转子断条故障进行了实验研究。
