摘要

An armature core (55) and a field core (53) are fitted directly to a cylinder block (57) so that they are cooled by a liquid flowing through a passage (58) inside this block (57). Accordingly, cooling can be made efficiently, the temperature rise of an armature winding (56) and a field winding (54) can be limited and their operation characteristics are improved. Since a heat pipe fitted to the armature core (55) or the field core (53) is inserted into the cooling passage (58) inside the cylinoer block (57) so that either core (53 or 55) can be cooled more efficiently. A bracket to which the cores are fixed is fitted to the cylinder block (57), and a cooling liquid passage communicating with the cooling passage (58) inside the cylinder block (57) is formed in this bracket or a heat pipe which is partially inserted into the cooling passage (57) is disposed on the bracket.
