Abstract

An asynchronous machine comprising a frequency changer, a machine housing (14), a rotor (1) with a rotor winding, a stator (2) arranged stationarily in the machine housing and having a stator winding, and a shaft (3) which supports the rotor (1) and by means of bearings (4, 5) is rotatably journalled in the machine housing, said rotor having a plurality of rods (6) and two short-circuiting rings (7, 8) to which the rods (6) are joined to form a rotor cage (9), in which asynchronous machine a shaft current occurs through said shaft (3) during operation. According to the invention a conductor (11) is arranged between the shaft (3) and the short-circuiting ring (7, 8) on each side of the rotor (1), where by connectors (12, 13) connecting the conductor (11) electrically to the shaft (3) and the short-circuiting ring (7, 8), respectively. In order to connect the conductor to the shaft the connector (12) is located at a point between the bearing and the rotor cage.
