SQUIRREL CAGE ROTOR COMPRISING SPLIT END RINGS AND MANUFACTURING METHOD OF SUCH A SQUIRREL CAGE ROTOR

摘要

The invention relates to a squirrel-cage rotor with shaft (2), rotor core (3) with rotor bars (4) and short-circuit rings (5) arranged inside, the short-circuit ring (5) consisting of a disk package (7) consisting of layers (6) is constructed with recesses and through which the ends of the rotor bars (4) protrude from the rotor laminations (3). Adjacent discs (6) in the disc package (7) are spaced apart by a gap (8). The gap between the two adjacent disks (6) caused by the gap is formed by the formations (61) arranged in the disks (6). In addition, a solder joint (9) is present in the gap (8) at least in the area of the formations (61). Furthermore, the invention relates to a method for producing a squirrel cage rotor.
