The M20C-600 and two MK couplings MK-1 made by TILKOM are used for investigations of a tram converter.

The 0.7 MW motor parameters are determined on the test bench with the torque transducer M40-50k. The measurement system enables torque, rotation speed and mechanical power to be proved. The measurement data are displayed both at the display unit and the computer screen. The appropriate software provides possibility of writing, storing and further processing and analyzing the data.
