A heat-conductive seal cover (34) is fitted to the entire periphery between a transmission case (33) and a cylinder block (31) and a heat-transfer gel (35) is sealed between a resin member (32) applied to the surface of an armature winding (5) and the seal cover (34) and between the resin member (32) and the cylinder block (31) so as to radiate the heat generated by a current flowing through the armature winding (5) to the cylinder block (31) and to the transmission case (33) through this heat transfer gel (35). Therefore, it is possible to check the temperature rise and the drop of operation characteristics of the armature winding (5). A highly heat-conductive ring (37) is fitted between the transmission case (33) and the cylinder block (31) through the highly heat-conductive seal cover (34) so as to radiate the heat generated by the current flowing through the armature winding (5) to the transmission case (33) through the cylinder block (31), the ring (37) and the seal cover (34). In this manner, the same action and effect as described above can be accomplished, too. |
