CHALLENGE

Endurance testing of multiple drives simultaneously requires precise measurement of electrical and thermal parameters, automated data acquisition and accurate reporting. Manual testing risked errors, slow throughput and inconsistent results across multiple DUTs.

SOLUTION

TMCS developed a custom DAQ system capable of testing 12 DUTs (Drive) simultaneously. Each DUT is equipped with programmable power sources, DC load banks, thermocouples and communication interfaces. The system integrates LabVIEW software, industrial PCs, and specialized hardware for data acquisition and control. Parameters such as voltage, current, power, overload/no-load voltages are measured automatically for all DUTs.

SPECIFICATIONS / FEATURES DESCRIPTION / PARAMETERS MONITORED
Temperature Rise Test
Monitors motor winding temperature at full load.
KWH Test
Measures power, voltage and current of each motor.
Line Regulation Test
Checks drive stability under varying input voltage at constant load.
Load Regulation Test
Evaluates drive performance under varying load at constant voltage.
