摘要： The totally-enclosed fan-cooled motor includes the stator 13; the rotor 4; the drive side bracket 6; the counter drive side bracket 8 arranged at the other end of the frame 10; a pair of the bearings 7 and 9 that support the drive side 1a and the counter drive side 1b of the rotation shaft 1; the external fan 15 that is arranged on an outer side of the counter drive side bracket 8, is mounted on the rotation shaft 1, and sends cooling air to the stator 13; the internal fan 5 that is arranged in the frame 10 and sends air in the motor to the rotor 4 and the stator 13 by circulating the air; the disk-shaped heat radiator 17 that is arranged on an inner side of the drive side bracket 6 and is mounted on the rotation shaft 1; the snow protection cover 20 that is mounted on an outside of the drive side bracket 6; the ventilation path 18 that induces part of the cooling air taken in from the external fan 15 to the drive side bracket 6 without contacting the frame 10; and the ventilation path 19 that is arranged between the drive side bracket 6 and the snow protection cover 20, and includes the outlet 19a that communicates with the ventilation path 18, causes the cooling air passed through the ventilation path 18 to pass through the heat radiator 17, and discharges the cooling air outside the motor.
