Abstract

1396327 Cooling electrical machine rotor coils UNELEC 18 May 1972 23531/72 Heading H2A A wound salient pole rotor for an electrical machine, e.g. an alternator comprises either at least one coil 100 or two mutually adjacent coaxial coils 2 ... 5 and a plane U-shaped metal cooling tongue 10 or 6 ... 8 disposed parallel to the plane of the coils and inserted between either the turns or the coils respectively, the periphery of the tongue being formed with notches 11...15 and projecting externally of the coil(s). Binding members 9, 19 and wedging devices 16 ... 18 disposed in the notches maintain the coil(s) in position on the rotor, and the tongue(s) may have a coating of electrical insulation, e.g. varnish, or an oxide if the tongue is of A1.
