FIELD: electrical engineering. ^ SUBSTANCE: invention relates to electrical engineering, particularly, to testing hardware, namely to synchronous machine test-benches. In compliance with this invention, the test-bench consisting of two synchronous machines with their three-phase windings connected to a common power source and shafts coupled via a chain gear, made up of drive and driven sprockets, a chain with drive and idle loops, a tensioning device arranged on the idle loop and composed of a sprocket and a fastened weight, differs in that an additional sprocket and its drive are arranged on the said drive loop to adjust its length. ^ EFFECT: simpler design and lower power losses. ^ 2 dwg |
