FIELD: stand testing of bearing assemblies of electric motors, possibly in industry and agriculture. SUBSTANCE: stand includes frame with openings for passing rod of tension device and with openings for securing stand to foundation and tested electric motor. Tension device is in the form of threaded rod supporting platform with central opening for rod and with four openings for mounting tested motor; tension spring whose terminal turns are supported by first surfaces of first and second supporting bases. First supporting base rests by its second surface upon lower surface of frame. Second supporting base rests by its second surface upon small fly-wheel mounted onto threaded portion of rod having cap in its other end. Centering holes of tested motor formed in its shaft ends provide mounting of motor in rotating centers whose cone tails are inserted into cone-like openings of struts formed as one piece with blocks fastened with the aid of bolt joints in slits of frame. EFFECT: reduced noise, lowered labor consumption for adjusting radial effort. 4 dwg
