摘要
主要分析永磁同步电动机短路故障。根据永磁同步电动机的基本理论,建立仿真模型,进行额定负载下正常运行和短路故障分析,如单相接地短路、两相短路和三相短路。用解析法验证仿真结果,2种方法所得结果吻合较好,表明建立该电机的仿真模型合理以及求解方法的可行性。
It is mainly to analyze short-circuit faults of permanent magnet synchronous motor. According to basic theory, it is founded by simulation model of permanent magnet synchronous motor. Normal operation and short-circuit faults, which are analyzed by simulation model. The later are mainly single-phase fault, 2-qSfauh and 3-bfauh. Analytical method is confirmed agreement with analysis of simulation, indicating the reasonable of simulation model of three-phase induction motor and the feasibility of solving.
