Abstract:

Based on the multi-loop method, the rotating torque and speed of the induction machine are analyzed.The fluctuating components of the torque and speed caused by rotor winding faults are studied.The models for calculating the fluctuating components are put forward.Simulation and computation results show that the rotor winding faults will cause electromagnetic torque and rotating speed to fluctuate;and fluctuating frequencies are the same and their magnitude will increase with the rise of the severity of the faults.The load inertia affects the torque and speed fluctuation, with the increase of inertia, the fluctuation of the torque will rise, while the corresponding speed fluctuation will obviously decline.

基于多回路方法, 对异步电机定子电流、转矩、转速进行了分析, 对转子绕组故障引起的电机转矩、转速的波动进行了深入研究, 提出了波动计算模型.仿真与计算结果表明:转子绕组故障引起电机转矩、转速波动;波动分量的大小、频率可定量计算;转矩与转速波动的频率相等, 波动的幅值随转子绕组故障严重程度增加而增加;负载转动惯量对电机转矩、转速有较大的影响, 负载转动惯量增加, 转矩波动分量的幅值增加而转速波动分量的幅值减小.
