TEST BENCH FOR ELECTRIC DRIVES Russian patent published in 2020 - IPC G01M13/02 G01R31/34 

FIELD: test technology.

SUBSTANCE: invention relates to tests in machine building. Summary: test bench for electric drives comprises load actuator, automatic control system and loading asynchronous motor. Output link of the loading drive is made with the possibility of kinematic connection with the output link of the tested electric drive and is equipped with a torque sensor. Automatic control system is connected to the loading drive, has the possibility of controlling the operator and has an input and an output. Automatic control system input is connected with torque sensor. Output link of the load-bearing drive is additionally equipped with a position sensor connected to the input of the automatic control system. Loading drive includes a loading asynchronous motor equipped with a digital speed sensor, an electromagnetic brake coupling, and a wave reducer with intermediate rolling elements. Automatic control system is connected by output to stator of loading asynchronous motor via frequency converter and is made with possibility of connection with control unit of tested electric drive.

EFFECT: higher efficiency of stand due to expansion of its functional capabilities.
