Specific embodiment
Below in conjunction with the accompanying drawings illustrating the present invention.
The good fire-proof motor of of the present invention a kind of thermal diffusivity as shown in Figure 1, including housing 1, stator core 2,
Rotor core 3, rotating shaft 11, centrifugal fan 4, temperature sensor 5 and alarm 6；Stator core 2 is provided with the housing 1；It is described
In stator core, 2 set rotor core 3；Rotatable rotating shaft 11 is provided with the rotor core 3；Cooling is provided with the housing 1
Water channel 12；The cooling water channel 12 is provided with the water inlet 10 and delivery port 9 for passing housing 1；2 side of the stator core is provided with
Near the first air vent 7 of cooling water channel 12；The second air vent is provided near 7 side of the first air vent on the rotor core 3
8；Centrifugal fan 4 is provided with positioned at 3 front end of rotor core in the rotating shaft 11；Temperature sensor is additionally provided with the rotor core 3
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 with the heat transfer of rotor core in rotor core, air is flowed in the presence of centrifugal fan
To in the first air vent of stator core, as the first air vent is near cooling water channel, thermal resistance is little, so as to increased 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 additionally provided with rotor core wherein, when the temperature of rotor core is too high, temperature sensor is sent out
Send instruction to alarm, alarm sends warning, and operator can be allowed to close fire-proof motor in time, it is to avoid fire-proof motor by
It is too high in temperature and directly scrap.
The good fire-proof motor of thermal diffusivity of the present invention, it is simple and practical, by arranging cooling water channel in casing, and
The first air vent and the second air vent are offered on stator core and rotor core, centrifugal fan is set in rotating shaft, defined 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 its use
Life-span.
Above-described embodiment technology design only to illustrate the invention and feature, its object is to allow person skilled in the art
