  • Dynamoelectric machine rotors with mechanical separators
    Patent number: 4390806
    Abstract: A rotor for a large dynamoelectric machine possesses abrasion prevention material between certain of the laminations in the rotor winding. In particular, while the rotor windings may generally be wound in a series-connected fashion, the use of adjacent parallel winding conductors requires the use of an abrasion prevention material disposed between adjacently lying parallel-connected conductors. The use of this material eliminates copper galling and the undesirable formation of copper particles.
