Electric machine having several rigid winding pieces formed as hollow conductors-hydraulic connection concept ii

Electric machine (1) having a rotor (3), a stator (2) and several rigid winding pieces (5)

• formed as hollow conductors, which form various coils of a winding (4) of the electric machine (1) and are each part of a cooling circuit of the electric machine (1), wherein the winding pieces (5) each have at least one lateral tap (34) in the region of their end sections (8), via which tap a coolant can be fed into the winding pieces (5) or removed from the winding pieces (5);
• wherein
• a hydraulic connection part (15) is provided, to which several of the winding pieces (15) are connected, wherein the connection part (15) has at least one channel (31, 32) which is in fluidic connection with several of the winding pieces (5), such that the coolant can be fed into the individual winding pieces (5) via the lateral tap (34) of the winding pieces (5), or a coolant coming out of the lateral taps (34) of the winding pieces (5) can be collected in the at least one channel (31, 32).
