Influence of Skewed Squirrel Cage Rotor with Intermediate Ring on Magnetic Field of Air Gap in Induction Machine
The article compares the flux density spectrum in air gap of squirrel-cage induction machine with different rotor geometries. The skewed squirrel cage with an intermediate ring and ordinary skewed squirrel cage are compared to the straight bars rotor using the finite element method. The novelty lies in a deep investigation in issues relating to rotor cage with an intermediate ring.
