Measurement of interturn short-circuits emulation on dual three-phase PMS motor

The published data contains measurement records made on a special permanent magnet synchronous motor (PMSM). The motor has a stator with winding taps. The winding taps can be used to emulate various severities of interturn short-circuits.

A detailed machine description and modeling can be found in the paper "Interturn short circuit modelling in dual three-phase PMSM" (https://dx.doi.org/10.1109/IECON49645.2022.9968364).  

The file name specifies the measurement conditions according to

spd10-5000rpm_fltNzP_XXNM.mat

N - Number of shorted turns (0-healthy operation)

P - Fault phase ( U or V)

XX - Load torque generated by a dynamometer

For example, the file spd10-5000rpm_flt1zu_25NM.mat contains data where one coil turn in phase U was shorted, and the machine was producing 25 Nm torque.

Measurement was performed by the microcontroller and synchronised with the control algorithm. The sample rate is 10 kHz for this reason. Each data file contains measured currents in stator coordinates as well as currents and voltages (control value) in rotor (dq) coordinates. These variables are measured for each three-phase sub-system. Measured motor position, speed and required motor speed are also included.
