PURPOSE:To prevent a coil from overheating by one temperature fuse by so mounting the fuse on a board fixed near the stator having a 3-phase coil structure as to be disposed at equal distances from two-phase different coils disposed in one stator slot of the stator. CONSTITUTION:A board 3 is mounted near a stator having a 3-phase coil structure by a mounting member 6. A temperature fuse 5 is so stood on the board 3 as to be disposed at equal distances from the two-phase different coils 2 in one stator slot of the stator. In the drawing, it is disposed between the U- phase coil 2 and the V-phase coil 2. Accordingly, a temperature fuse 4 is disposed extremely at the two-phase coils 2 of the three-phases, and beat is conducted from the two-phase coils 2 to the fuse 4 equally and rapidly. As a result, even if any of the coils 2 generates beat due to an overload, an overheating state can be effectively prevented. |
