ABSTRACT:
An electrical machine, particularly a rotary current generator, has a stator, a claw pole rotor, a stator winding having winding heads extending outwardly beyond ends of the surface-cooled stator, a metal housing surrounding the stator and serving for withdrawal of heat from an interior to an exterior of the housing, a zinc die cast alloy in which the winding heads are electrically insulatingly embedded and which conduct heat to the metal housing, and an electrically insulating layer completely coating each of the winding heads and located between each of the winding heads and the zinc die cast alloy.
