The scheme describes the open-chain stand for testing the transmission system of industrial electric-cars. Beside the basic assemblies (driving group - 1, sample transmission - 2, electromagnetic brake - 3) the stand is completed with measuring devices (torque measuring couplings - 4). The angular velocity is controlled by means of an Ilgner group - 6. The value of angular speed and torque are continuously monitored digitally and registered analogically (in respect with time).
