The diameter and height of the fan blade of the three-level fan are both greater than second level fan.The level-one fan setting
For tube-axial fan.The second level fan is set as centrifugal fan.
The three-level fan is set as centrifugal fan.The motor flywheels in flywheel axle sleeve by being installed with fixed spiral shell
Bolt I fixes motor flywheels.The motor stator is fixedly connected by fixing bolt II with the end face of motor stator fixing seat.
The invention has the following advantages: the present invention is equipped with three-level air duct, this three-level after using above technical scheme
The air duct that air duct can produce three-level booster-type is cooling, and cooling effect is made to be greatly improved.Level-one fan of the invention is axis stream wind
Air in surrounding enviroment is pressed into air duct with biggish flow by fan.Into motor stator region air-flow middle section by two
Grade fan sucking, the working region of three-level fan is entered by the hole on flywheel end face, straight because of force 3 wind pectinid fan leaf
Diameter and height are both greater than second level fan, so being discharged completely by three-level fan by the fan forced air-flow of second level；Into calmly
The air-flow peripheral portion of subregion directly passes through the hole on flywheel end face by stator clearance between poles and enters third level centrifugal fan
Working region and be discharged by three-level fan.The present invention devises the three-level booster-type structure of air-flow, and first order fan is axis stream
Formula, it is ensured that there are more air to enter air duct, second level fan makes the air-flow of motor stator region middle section increase pressure
Power keeps the air-flow for entering third level fan more more abundant, compensates for the gap between motor stator and rotor and stator
The lesser defect in gap between coil.
