増大し効率が低下するなどの欠点があった。However, with such a structure, as the stator (2) becomes longer, the temperature of the water coming out of the water gap (3) increases significantly.
6) increases in temperature, and the temperature in the axial direction increases. To deal with this, there is a conventional method in which cooling water flows from the axial center of the stator (2) radially inward into the water gap (3), but although the cooling effect is improved, the mechanical loss is significant. There were disadvantages such as increase in the amount of fuel and reduced efficiency.

The cooling water cools the stator (2) and rotor (6) through the pump (from the force as shown by the arrow from water gap (3) and gap (I3) to gap 04), so the stator (2) The cooling area is greatly increased, the cooling effect is large, and the temperature effect in the axial direction is reduced. Further, due to the filling (I6), the increase in stirring loss caused by rotation of the rotor (6) is small.

The agitation loss caused by this can be extremely reduced. Further, the spacer (15) may be provided with a circumferential round hole, oval hole, square hole, slot hole, etc. to allow flow in the circumferential direction, and the spacer (05) and the stuffing (16+) may be integrated. ,
The spacer (I5) and the stator wedge (121) may be integrated.

ができるすぐれた効果がある。As described above, according to the present invention, since the filling material is provided in a liquid-cooled rotating electrical machine and closes the gap between the stator wedge and the spacer, the stator core and stator winding of the stator can be cooled. In particular, the temperature difference in the axial direction becomes smaller. In addition, due to the filling, the increase in stirring loss due to the rotation of the rotor is small, and there is no sudden temperature rise of the cooling water due to increased stirring loss and the accompanying water boiling phenomenon, and insulation deterioration of the stator windings is prevented. This has the excellent effect of making it possible to obtain a highly reliable liquid-cooled rotating electric machine.
