A cooling system

The invention relates to a cooling system (28) for a motor comprising a transmission shaft (26) and a rotor shaft (2) of a rotor (4). The cooling system (28) comprises a first sleeve (13a) and a second sleeve (13b), wherein the first sleeve (13a) surrounds the transmission shaft (26) coaxially, the second sleeve (13b) surrounds the first sleeve (13a) coaxially, the first sleeve (13a) and the second sleeve (13b) define a first flow space (14) for a cooling medium, the rotor shaft (2) surrounds the second sleeve (13b) coaxially, and the second sleeve (13b) and the rotor shaft (2) define a secondflow space (6) for the cooling medium. 本发明涉及种用于电机的冷却系统(28)，该电机包括传动轴(26)和转子(4)的转子轴(2)，该冷却系统(28)包括第套管(13a)和第二套管(13b)，其中第套管(13a)同轴地包围传动轴(26)，第二套管(13b)同轴地包围第套管(13a)，第套管(13a)和第二套管(13b)限定用于冷却介质的第流动空间(14)，转子轴(2)同轴地包围第二套管(13b)，第二套管(13b)和转子轴(2)限定用于冷却介质的第二流动空间(6)。
