PURPOSE: A liquid-cooled electric device is provided to cool a rotor and a winding head through cooling of a stator pack of an electric device having a liquid jacket cooling part. CONSTITUTION: A liquid-cooled electric device(20) includes a device housing(21) and a cooling unit(24). The device housing receives a rotor(2) and a stator winding(7). The stator winding includes a winding head(8) arranged in a winding head space(26). The cooling unit includes a liquid cooling circuit(23) and a cooling coil(10). A liquid cooling circuit has at least one air cooling part(25) and a stator jacket cooling part(9). The air cooling part is connected to the rotor in order to circulate the air of the winding head space. The cooling coil is guided to an outer part of the winding head through winding head spaces.
