In the paper were done some comparative tests of direct and alternating dynamometers with power-electronic device witch has possibility of returning energy to the main. There were used three types of motors witch had near the same rated torque and different speed. As criteria of the evaluation were used the values of stray load losses (method B), the dispersion of measured points, the fluctuation of tested motor input power and the shape of the current returned into the main. The measurements of torque were made by three devices a torque-meter, a force sensor and an electronic scale. There were presented the results of the tests, analysis of this results, conclusion, advantages and disadvantages of the devices.
