Replication Data for: Modelling mechanical faults in induction motors using magnetic equivalent circuits and lumped-element shaft-bearing dynamics

A magnetic equivalent circuit induction motor model is combined with a lumped-element rotor dynamics model. Their combination is analysed for (i) rotor position, (ii) rotor acceleration, (iii) unbalanced magnetic pull, (iv) bearing acceleration, and (v) stator currents in the presence of the following mechanical faults: (i) no-fault case, (ii) a stator outer race misalignment, (iii) a rotor mass unbalance, (iv) a bearing outer race spall fault, (v) a bearing inner race spall fault, (vi) a bearing ball spall fault. The dataset is stored as the complete state and input time-series of both models. Additionally, the dq-transformed stator currents are provided.

将磁等效电路感应电机模型（magnetic equivalent circuit induction motor model）与集总参数转子动力学模型（lumped-element rotor dynamics model）进行耦合，针对包含无故障工况在内的6类机械故障场景，分析该耦合系统的转子位置、转子加速度、不平衡磁拉力（unbalanced magnetic pull）、轴承加速度与定子电流五类物理量。所涵盖的机械故障具体包括：(i)无故障工况，(ii)定子外座圈不对中（stator outer race misalignment），(iii)转子质量不平衡（rotor mass unbalance），(iv)轴承外座圈剥落故障（bearing outer race spall fault），(v)轴承内座圈剥落故障（bearing inner race spall fault），(vi)轴承滚珠剥落故障（bearing ball spall fault）。本数据集以两个模型的完整状态及输入时间序列形式存储，同时额外提供dq变换定子电流（dq-transformed stator currents）。
