Abstract (en)
[origin: WO2015132116A2] The invention relates to an electric machine (1) comprising a rotor (3) cooed by a cooling gas and a stator (5) which surrounds the rotor (3) and which comprises several partially laminated cores (13). Said partially laminated cores (13) are successively arranged in an axial direction which is parallel to a rotational axis (7) of the rotor (3) and are separated from each other by flow channels (23) which are open on the rotor side for guiding the cooling gas to the rotor (3).
