Conductor Bar and Associated Rotor and Rotating Electrical Machine

Conductor Bar and Associated Rotor and Rotating Electrical Machine

The conductor bar (17) for a squirrel-cage rotor comprises at least one end (17a) which is partially slit such that a section of the end forms two symmetrical branches (22, 23) relative to the slit (21). The centre of gravity (G3, G4) of each branch is arranged such that the branches flare towards t...

Zusammenfassung:The conductor bar (17) for a squirrel-cage rotor comprises at least one end (17a) which is partially slit such that a section of the end forms two symmetrical branches (22, 23) relative to the slit (21). The centre of gravity (G3, G4) of each branch is arranged such that the branches flare towards the outside of the bar under the effect of centrifugal force when the rotor is rotated.
