  • Multi-layer insulation for winding elements of dynamoelectric machines (D.E.M.s)
    Patent number: 5973269
    Abstract: An insulation system for the windings of a dynamoelectric machine is described wherein a bundle of insulated conductors is provided with layers of groundwall insulation. The innermost layer of groundwall insulation has superior corona discharge resistant properties. A second layer of groundwall insulation which has a corona discharge resistance somewhat less than the innermost layer of groundwall is superimposed on the innermost layer.

  • Spark suppression of induction type rotors of dynamoelectric machines
    Patent number: 5886443
    Abstract: A rotor for an induction motor of the squirrel cage type wherein the rotor bars are exposed to a resilient anti-sparking compound in the rotor slots of the machine. The rotor bars are provided with a longitudinal slot to permit the insertion of the anti-sparking compound after assembly of the squirrel cage rotor. Alternatively, the laminations may be shaped to produce a longitudinal groove in the rotor bar slot to permit the insertion of the anti-sparking compound in the groove so produced. Of course, both the rotor bar and the rotor slot may both be provided with complimentary slots adjacent one another in which the anti-sparking compound may be injected.
