The cooling fan 8 rotates with the rotation of the rotor shaft 7, and a suction force is generated inside the electric motor 1. Thereby, cooling air (outside air) is taken into the electric motor 1 through the plurality of air inlets 11. The taken-in cooling air absorbs the heat generated inside the electric motor 1 while absorbing the heat generated inside the motor 1, the gap between the stator core 3 and the rotor core 4, and a plurality of ventilation ducts 13 provided inside the rotor core 4.

Alternatively, it is discharged in one direction on the traveling wheel 19 side. At this time, the cooling air to be exhausted diffuses and is exhausted by the exhaust port 12 provided on the stator frame 2, but the exhaust air guide member 14 causes the track girder 23 side, or

Side or the traveling wheel 19 side. That is, the diffusion is suppressed by the exhaust guide member 14 and the exhaust is concentrated on the track girder 23 side or the traveling wheel 19 side. As a result, most of the noise is canceled out by the noise generated by the track girder 23 or the traveling wheels 19 and is thus sound-insulated.
The noise generated by the rotation of the cooling fan 8 is also blocked by the thickness of the stator frame 2.

Cooling air discharged from the exhaust port 12 and the track girder 23 side or the running wheel 19 side.
The exhaust guide member 14 that discharges in one direction is provided in the exhaust port 12 portion, so that noise generated by the rotation of the cooling fan 8 and discharged from the exhaust port 12 is reduced to the track girder 23 side or
It can be discharged in one direction on the traveling wheel 19 side, and can be canceled and sound-insulated by the sound generated by the track girder 23 or the traveling wheel 19. Therefore, the noise can be reduced without providing a sound absorbing material as in the related art. By the way, as a result of actually measuring and comparing the noise level emitted from the monorail vehicle using the motor of the conventional structure and the noise level emitted from the monorail vehicle using the motor of the present embodiment, the results are almost the same. The level was confirmed.
