Dataset for Early Detection of ITSC Faults in PMSMs

The published dataset contains the following: faulted_PMSM_data.mat - identified flux maps of a faulted Prius PMSM extracted from FEA-simulation (4-D with the size of 11x11x11x61) simulation_data.zip - transient simulation data (6667 records of dq-currents) training_data.zip - DWT features extracted from the simulation data and experimental data ( Wavelet levels for 6667 sample) Transformer_Classifier.ipynb - Transformer model with training loop In the transient simulation the naming convention is the following: healthy: simulation_results_hlth_Mload_XX.X_n_YYY_step_time_ZZZ_speed_step.mat, where X is the load, Y is the speed and Z is the time where the transient happened faulted: simulation_results_Rf_XX_Mload_YYY_n_ZZZ_phW_speed_step.mat, where X is the fault resistance, Y is the load, Z is the speed and W is the faulted phase index ( 1 - U, 2 -V, 3 - W) In the training data, each csv is a given wavelet level for every sample . The "exp" notation means that it is extracted from experimental data. Detailed description can be found in the paper: " Early Detection of ITSC Faults in PMSMs Using Transformer Model and Transient Time-Frequency Features" (https://dx.doi.org/XXX).本已发布数据集包含以下内容： - faulted_PMSM_data.mat：故障型普锐斯（Prius）永磁同步电机（PMSM）的已识别磁通映射图，数据源自有限元分析（FEA）仿真，为4维数据集，尺寸为11×11×11×61。 - simulation_data.zip：瞬态仿真数据集，包含6667组dq轴电流记录。 - training_data.zip：从仿真数据与实验数据中提取的离散小波变换（DWT）特征，对应6667个样本的小波层级。 - Transformer_Classifier.ipynb：搭载训练循环的Transformer模型脚本。 瞬态仿真文件的命名规范如下： - 健康工况文件命名格式：simulation_results_hlth_Mload_XX.X_n_YYY_step_time_ZZZ_speed_step.mat，其中X代表负载幅值，Y代表电机转速，Z代表瞬态工况发生时刻。 - 故障工况文件命名格式：simulation_results_Rf_XX_Mload_YYY_n_ZZZ_phW_speed_step.mat，其中X代表故障电阻阻值，Y代表负载幅值，Z代表电机转速，W代表故障相索引（1对应U相、2对应V相、3对应W相）。 训练数据中，每个CSV文件对应全体样本的某一指定小波层级；文件名中带有"exp"标识的，表示该数据源自实验采集。 数据集详细说明可参阅论文《基于Transformer模型与瞬态时频特征的永磁同步电机匝间短路（ITSC）早期检测》（Early Detection of ITSC Faults in PMSMs Using Transformer Model and Transient Time-Frequency Features）（链接：https://dx.doi.org/XXX）。
