Abstract

The invention relates to a simple and efficient method for cooling encapsulated electrical machines. An electrical machine of this kind consists of a stator (S), a rotor (R), and a casing (K) which closes off the rotor from the stator, forming a seal. For efficient cooling, the stator has a liquid cooling device with a corresponding stator cooling circuit (SK). The casing (K) also forms a part of the outer wall of the cooling circuit (SK).
