This stand is used in electromechanical tests on the parameters of electrical motors in laboratory and industrial conditions. Its construction ensures automatic positioning of the tested electrical motor for a reduced period of time. The stand is built on a foundation (1), on which vertical stands (11 and 12) are attached perpendicularly, and hinged on shafts (21 and 31), connected to electrical motors. The foundation represents a monolithic concave body, with a bottom (101) and lateral walls (102 and 103), in the inside of which are four step electrical motors (2 and 3), which are fastened in pairs to the front mobile frame (6) and a hind frame (6') with a n-shaped form, whose walls (61 and 62) are parallel to the lateral walls of the foundation. The front mobile frame is fastened to the lateral walls. Toward the middle of the bottom is fitted a reverse, asynchronous electrical motor (8), connected via an axis (9) and a fork (10) to the front mobile frame, and the hind frame. The step electrical motors, via its shafts and connectors (22 and 32), are linked, respectively, to vertical stands (11 and 12), which pass, respectively, through apertures in the top plane of the front mobile frame and the hind frame, on which a bottom holder (13) is placed. On the top loose end of the vertical stands, implemented along its entire length with a carving, are a front and back mobile plate (14 and 14'), below which is hinged a top holder (15).
