The figures are a sectional view taken along the line If-II in FIG. 1, FIG. 3 is an enlarged sectional view of essential parts showing a stator of a rotating electrical machine according to an embodiment of this invention, and FIG. 4 is a sectional view taken along the line TV-IV in FIG. 3. It is a diagram. In the figure, 1 is a stator core, 2 is a slot, 3 is a stator coil, 6 is a cooling passage, and 7 is a radial ventilation passage. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims

[Scope of utility model registration request]

A stator coil is installed in a slot in the stator core, and a plurality of cooling passages are formed in the circumferential direction near the center of the stator core and passing through the core in the longitudinal direction, wherein the cooling passage is installed in the stator core. A stator for a rotating electrical machine, characterized in that a radial ventilation passage is formed in communication with the cooling passage, and cooling air passing through the cooling passage is led out to the outer circumferential side of the stator core through the radial ventilation passage.
