Description

Permanent magnet synchronous motors (PMSM) are widely used in industry applications such as power plant, manufacturing lines, high-speed trains, and electric vehicles. Unexpected faults of PMSM as a key component in most of the engineered systems can lead to significant financial, societal, and human losses. Therefore, machine-independent fault diagnosis methodologies are important to diagnose PMSM faults with different capacities while maintaining the same performance. This article reports and discusses vibration and motor current dataset for PMSM stator fault detection and identification under different motor capacities. Dataset are acquired using one ceramic shear ICP based accelerometer and three current transformer (CT) with National Instruments (NI) data acquisition (DAQ) board under international organization for standardization (ISO) standard. PMSM conditions including normal, coil-coil short-circuit fault, and inter-turn short-circuit fault with three different capacities such as 1.0 kW, 1.5 kW and 3.0 kW are demonstrated. PMSM including three different capacities are operated under same load condition and same rotating speed. Those datasets can be used to verify newly developed state-of-the-art methods for PMSM fault diagnosis. ---- Description of vibration file format ---- aaaaW_bb_cc_vibration_dddd.tdms : This file includes "dddd" short circuit fault vibration data of z-direction with "bb.cc" % severity acquired from the motor whose capacity is "aaaa" W. For examples, "1000W_0_00_vibration_interturn.tdms" means healthy inter-turn short circuit vibration data of z-direction acquired from the motor whose capacity is 1.0 kW and "1500W_5_70_vibration_coil.tdms" means coil-coil short circuit fault vibration data of z-direction with 5.70 % severity acquired from the motor whose capacity is 1.5 kW. ---- Description of motor current file format ---- aaaaW_bb_cc_current_dddd.tdms : This file includes "dddd" short circuit fault motor current data of three phases with "bb.cc" % severity acquired from the motor whose capacity is "aaaa" W. For examples, "1000W_0_00_current_interturn.tdms" means healthy inter-turn short circuit motor current data of three phases acquired from the motor whose capacity is 1.0 kW and "1500W_5_70_current_coil.tdms" means coil-coil short circuit fault motor current data of three phases with 5.70 % severity acquired from the motor whose capacity is 1.5 kW.

Files

Steps to reproduce

The dataset was acquired under different motor capacities such as 1.0 kW, 1.5 kW and 3.0 kW. Each motor condition was experimented with PMSM seeded by artificial fault including coil-coil short-circuit and inter-turn short-circuit. Vibration data and motor current data are collected from NI DAQ for 120 seconds at a sampling rate of 25.6 kHz and 100 kHz, respectively.
