Abstract [English] The invention relates to a cooling arrangement for cooling of an electrical synchronous machine comprising a two-layer single coil winding, the two-layer single coil comprising an airgap between different single coils in a stator slot, the stator slot being open towards a radial air duct of a rotor core and to be part of an air circuit inside said electrical synchronous machine, the air circuit configured to be driven by one or more rotating radial air ducts and a fan. [French] L'invention concerne un agencement de refroidissement pour le refroidissement d'une machine synchrone électrique comprenant un enroulement à bobine unique à deux couches, la bobine unique à deux couches comprenant un entrefer entre différentes bobines uniques dans une fente de stator, la fente de stator étant ouverte vers un conduit d'air radial d'un noyau de rotor et pour faire partie d'un circuit d'air à l'intérieur de ladite machine synchrone électrique, le circuit d'air étant conçu pour être entraîné par un ou plusieurs conduits d'air radiaux rotatifs et un ventilateur.
