In order to solve the above technical problems, the technical solution that the utility model uses is：It is cold to provide a kind of motor drainage
But fan, including：Bottom plate, fan blade and guide sleeve, front of the bottom plate on the rotor of motor and positioned at motor are described
Inverter is located at the front of bottom plate, and the motor is located at engine side, and annular array is distributed in the four of bottom plate to the fan blade successively
In week, the guide sleeve is arranged concentrically on the outside of bottom plate, and the end of fan blade is connected with the inner wall of guide sleeve respectively, the bottom
It is provided with axis hole in the middle part of plate, the mounting hole that annular array is distributed in axis hole surrounding is provided on the bottom plate.
In one preferred embodiment of the utility model, annular array is distributed in the front edge of bottom plate to the fan blade successively
It goes up and extends outwardly.
In one preferred embodiment of the utility model, the fan blade is inclined such that cooling wind to the front of bottom plate respectively
Blow to inner wall and the rear of guide sleeve.
In one preferred embodiment of the utility model, there are one circular cowlings for the front end setting of the guide sleeve.
In one preferred embodiment of the utility model, the circular cowling is integrated with guide sleeve.
In one preferred embodiment of the utility model, the medial surface of the circular cowling is connected with fan blade.
In one preferred embodiment of the utility model, annular array is provided with several ventilation lightening holes on the bottom plate.
The utility model has the beneficial effects that：A kind of motor that the utility model is pointed out drains cooling fan, and bottom plate follows
Motor is rotated, when fan air draught, air-flow preferentially by and cooling inverter, ensure that machine uses in the high temperature environment, wind
It fans sucking cooling wind to rotate by fan blade, cooling wind is guided to motor by centrifugation to periphery by guide sleeve, through passing through fan centrifugation is added
The cooling wind of pressure, is fully cooled rotor and stator, has cooled down the cooling wind after motor and continues through motor front end cover and blows to
Engine, cooling engine, it is ensured that cool down the cooling effect and working efficiency of inverter, motor and engine, use is more stablized.
