ABSTRACT:
A cooling structure and a rotating electric machine with the cooling structure are provided. The cooling structure produces sufficient reductions in the temperature of the stator core while at the same time not causing a large reduction in the output of the rotating electric machine. The rotating electric machine is provided with a first cooling medium passage formed in the slot. In addition, a second cooling medium passage is provided which extends in parallel to the first cooling medium passage and allows flow of the same cooling medium as the first cooling medium passage. The stator core comprises at least a section of the passage wall of the second cooling medium passage. The second cooling medium passage is disposed so that the second cooling medium passage does not impede the flow of magnetic flux in the stator core.
