Note
Connecting cooling circuits in parallel
If you connect the cooling circuits of the stator segments in series, the cooling circuits
will contain coolant at different temperatures.
• Connect the stator segment cooling circuits in parallel. This ensures that each stator
segment is filled with coolant having the same intake temperature.
Ensure the same pressure drop and an even flow in every stator segment.
Influencing variables for this are:
• The tube lengths
• The tube material
• The tube cross-section
• The tube routing
• Regulation of the flow rate
Example for interconnecting cooling circuits
The following figure shows an example of a parallel connection of the cooling circuits of
6 stator segments. Due to the chosen positions for the water intake (IN) and the water
outlet (OUT), all cooling circuits contain an even flow.
