2. Description of the Related Art
An art for cooling a stator in an electric rotating machine (a motor, a generator, or a motor-generator) is disclosed, for example, in Japanese Patent Application Laid-Open No. 2002-186211.
In the electric rotating machine disclosed in the aforementioned publication, a plate is provided between segmental cores, and the plate is sealed with resin. It is difficult to perform an operation of molding the plate with resin.
In the electric rotating machine disclosed in the aforementioned publication, a slot serves as a cooling liquid passage, and a coil is provided in the cooling liquid passage. Thus, the number of combinations of a cooling liquid flowing through the cooling liquid passage and a material for the cores is limited.
