<P>PROBLEM TO BE SOLVED: To materialize a structure for improving efficiency of transferring heat from a coil end part to a casing in a rotating machine in which the coil end part of a stator coil is bent toward the casing side. <P>SOLUTION: A heat conducting member 15 is disposed between each coil end 13a of the coil end part 13 and the casing over the whole circumference in the circumferential direction of a stator core 3, the stator core 3 is inserted in the casing to make the metal block 19a and the peripheral insulating material 21a of the heat conducting member 15 abut on each coil end 13a and the casing. Thereby, the coil end 13a is thermally connected to the casing through the heat conducting member 15 with heat transfer efficiency higher than that of an insulating mold resin with interphase insulation between the coil ends 13a secured. At this time, the stator core 3 is inserted in the casing by making the heat conducting member 15 abut on the coil end 13a, and a bent part 13b of the coil end part 13 is held in a shape bent toward the casing side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
