Description

The double-cooling fan wound rotor three-phase asynchronous motor
Technical field
The utility model relates to the motor technology field, is specifically related to a kind of double-cooling fan wound rotor three-phase asynchronous motor that is applicable to derrick crane.
Background technology
What wound rotor three-phase asynchronous motor in the market adopted is common external fan cooling structure, the heat that motor produces externally dispels the heat by support and support surface radiating muscle, external fan produces wind path the electric machine stand surface is cooled off, owing to limited to by support surface radiating area, adding between motor internal hot-air and the outside cold air can't sufficient heat exchange, seriously limit the selection of motor heating load, namely limited the power output of motor.
Summary of the invention
The purpose of this utility model is in order to overcome defects, and the double-cooling fan wound rotor three-phase asynchronous motor of a kind of simple in structure, good cooling results, long service life is provided.
To achieve these goals, the double-cooling fan wound rotor three-phase asynchronous motor of the utility model design, comprise support, rotating shaft, electric motor end cap, high end cap, stator core, rotor core and be positioned at collector ring in the rotating shaft in the rotor core outside, in the rotating shaft in the described electric motor end cap outside external fan is installed, in the rotating shaft between the end face of described rotor core and the described collector ring internal fan is installed, described electric motor end cap and high-end covering have fresh air inlet and exhaust vent.
In technique scheme, described fresh air inlet is positioned on the periphery of described electric motor end cap, and described exhaust vent is positioned on the dust exhausting hole of high end cap.
Described fresh air inlet and described exhaust vent communicate.
The utility model has increased interior wind path on the basis of outer ventilation circuit, air duct in namely forming by end cap, rotor core, internal fan, high end cap, all have ventilation hole at end cap and high-end covering, rotating shaft drove the internal fan rotation and produces blast when motor rotated, the hot-air of motor internal is taken out of, and cool exterior air replenishes motor internal in succession, so loops cold and hot exchange, so greatly improve the radiating effect of motor, prolonged the useful life of motor.Internal fan is positioned at the position of former rotor dust board, substituted former rotor dust board, the wind that internal fan drove when rotating shaft was rotated not only can clean the carbon dust dust in the high end cap, can also lower the temperature to ring collector for electric motor, prolong collector ring useful life, its effect is far superior to former rotor dust board.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Double-cooling fan wound rotor three-phase asynchronous motor as shown in Figure 1, comprise support 9, rotating shaft 6, electric motor end cap 1, high end cap 3, stator core 10, rotor core 11 and be positioned at collector ring 12 in the rotating shaft 6 in rotor core 11 outsides, in the rotating shaft 6 in electric motor end cap 1 outside external fan 8 is installed, in the rotating shaft 6 between the end face of rotor core 11 and the collector ring 12 internal fan 5 is installed, has fresh air inlet 2 and exhaust vent 4 on electric motor end cap 1 and the high end cap 3.Fresh air inlet 2 is positioned on the periphery of electric motor end cap 1, and exhaust vent 4 is positioned on the dust exhausting hole of high end cap 3.Fresh air inlet 2 and exhaust vent 4 communicate.
Ventilation hole on support 9 of the present utility model, external fan 8 and the external fan cover 7 consists of outer ventilation circuit (referring to the indication of the arrow among Fig. 1), external fan 8 is loaded on electric motor end cap 1(as shown in Figure 2) outside rotating shaft 6 on, rotating shaft 6 drove external fans 8 and rotates and produce blast and form distinguished and admirablely when motor rotated, and the heat that outer ventilation circuit is taken away support 9 surfaces is crossed in wind circulation; Electric motor end cap 1, support 9, stator core 10, wind path in the common formation of ventilation hole on rotor core 11 and the high end cap 3 (referring to the indication of the arrow among Fig. 1), internal fan 5 is loaded in the rotating shaft 6 between iron core of rotor of motor 10 end faces and the collector ring 12, have fresh air inlet 2(on the electric motor end cap 1 as shown in Figure 3), high end cap 3(is as shown in Figure 4) on have exhaust vent 4(as shown in Figure 5), rotating shaft 6 drive internal fans 5 rotation generation blast formed distinguished and admirable when motor rotated, the hot-air of motor interior is taken out of, cool exterior air replenishes motor interior in succession, so loop cold and hot exchange, the inner heat that produces in the time of can the fast reducing motor operation.By the distinguished and admirable circulation of two-way to motor heat dissipation, thereby greatly improved the heat-sinking capability of motor, broken through long-pending limited " bottleneck " of motor surfaces, prolonged the useful life of motor.
The content that is not described in detail in this specification belongs to the known prior art of this area professional and technical personnel.
