FIELD: electric engineering.
SUBSTANCE: invention relates to testing equipment, in particular to electric equipment of test stands; it can be used for testing of roller chains or chain gears. Device includes drive motor and load generator, which shafts are interfaced through chain gear containing roller chain under testing, driving and driven sprockets. Thereat synchronous machines are used as motor and generator. Generator has three-phase armature winding at stator and exciting circuit at rotor; motor has main and auxiliary three-phase armature windings at stator. Main armature winding of motor is star-connected and switched to output of voltage regulator in parallel to armature winding of generator. Start of auxiliary armature winding of motor is connected to voltage regulator output and its finish is connected to outputs of alternate current rectifier. Series-connected exciting windings of motor and generator with resistor connected in parallel to one of them are switched to rectified current outputs. In this regard gear ration is equal to ratio of motor and generator pole number.
EFFECT: minimisation of power costs for testing.
