Sensor 5；The temperature sensor 5 is connected with the alarm 6 outside housing 1；The shape of the cooling water channel 12 is in the shape of a spiral.
When fire-proof motor works, the temperature of stator core and rotor core can rise, and the now rotating shaft of fire-proof motor drives
Centrifugal fan is started working, and so in the presence of centrifugal fan, air has been internally formed circulation, stator core in fire-proof motor
In the second air vent in the heat transfer to rotor core of rotor core, air is flowed into the presence of centrifugal fan
Into the first air vent of stator core, because the first air vent is close to cooling water channel, thermal resistance is small, so as to add air and water
Heat exchange amount, it is ensured that air temperature reduction after be further continued for being circulated in the inside of fire-proof motor, so as to reduce stator iron
The temperature of core and rotor core, it is ensured that the normal operation of fire-proof motor.
Temperature sensor is wherein additionally provided with rotor core, when the temperature of rotor core is too high, temperature sensor hair
Send instruction to alarm, alarm sends alarm, and operator can be allowed in time to close fire-proof motor, it is to avoid fire-proof motor by
It is too high and directly scrap in temperature.
The good fire-proof motor of thermal diffusivity of the present utility model, it is simple and practical, by setting cooling water channel in casing,
And offered on stator core and rotor core centrifugal fan is set in the first air vent and the second air vent, rotating shaft, formed
Interior circulation wind path, reduces the temperature of stator core and rotor core, it is ensured that the normal operation of fire-proof motor, extends it
Service life.
Above-described embodiment is only to illustrate technical concepts and features of the present utility model, and its object is to allow be familiar with technique
Personage can understand content of the present utility model and be carried out, protection domain of the present utility model can not be limited with this,
