ABSTRACT:
The invention relates to an asynchronous motor comprising a stator or a cage rotor, said cage rotor comprising a shaft (1) and a laminated bundle (2) and rotor rods (3) are arranged within the laminated bundle, running through the openings (10) of each end plate (9) at both ends of the laminated bundle (2) and terminated with a short-circuit ring (4) which electrically connects the ends of the rotor rods (3) on one side of the cage rotor. Each end plate (9) comprises a circumferential projection which at least partly covers the short circuit ring (4) on the outside thereof with a positive fit and each end plate (9) contains a part of the rotor rod (3) and a part of the short circuit ring (4).
