Definitions

  • magnet wire transformer coils include use in electric motor stator slots as shown in FIG. 3.
  • the wire conductors 30, base coated with a high-temperature wire enamel 31 and an aromatic polysulfone adhesive overcoat 32 may be wound in the coil retaining slots 34 between the teeth 35 of the main magnetic core 36 of the stator of a dynamoelectric machine such as a motor.
  • the polysulfone adhesive overcoat may then be fused together at coil winding contact points 37.
  • slot liners 38 which may be formed of paper, asbestos or other suitable material. The irregular interstices or air spaces 39 between adjacent insulated conductors can also be seen.
