摘要
The arrangement has two asynchronous machines (1,2) with rotors (12,22) mechanically fixed to each other. The rotor windings (14,24) are electrically connected via conductors (40) that rotate with them and the stator winding (13) of the first machine is directly connected to a three-phase supply (41) by contacts (42). The stator winding (23) of the second machine is connected to a special frequency converter (30) designed to enable power flow in both directions both above and below the natural revolution rate.
