Multimodal Signal Dataset for Fault Detection in PMSM-Driven Elevators Under Real Operating Conditions

This dataset contains synchronized time-series recordings of current and vibration signals collected from a fully operational residential elevator system equipped with a surface-mounted Permanent Magnet Synchronous Motor (PMSM). The data were acquired under healthy and faulty operating conditions, across various load levels and motion directions. The dataset supports research in predictive maintenance, signal analysis, and fault classification for PMSM-based elevator drives. All data were collected non-intrusively using industrial sensors: Hioki PW3390 power analyzer for current and THD, Triaxial accelerometer (ISO 20816-3 compliant) for vibration. The system is a 9-stop, 6-passenger MRL elevator, driven by a 5.1 kW, 12-pole PMSM motor. No signal post-processing was applied; raw sensor values are preserved for reproducibility.本数据集包含从全工况正常运行的住宅电梯系统采集得到的电流与振动信号同步时序记录，该电梯搭载有表面安装式永磁同步电机（PMSM）。数据采集覆盖健康工况与故障工况，涵盖不同负载等级与运行方向。本数据集可支撑基于PMSM的电梯驱动系统的预测性维护、信号分析及故障分类相关研究。 所有数据均通过工业传感器以非侵入式方式采集，所用设备包括：用于采集电流与总谐波失真（THD）的日置PW3390功率分析仪，以及符合ISO 20816-3标准的三轴加速度传感器（用于振动信号采集）。 该电梯系统为9层站、额定载客6人的无机房（MRL）电梯，由一台5.1kW、12极的PMSM驱动。 未对信号进行任何后处理，保留原始传感器数值以确保实验可重复性。
