Another plus startup winding, will not also produce vibration and step-out in load changing on son.Wherein outer rotor air duct brushless electric machine, generally
Using the structure design of motor plus independent fan blade.The shortcoming of this design is that fan blade takes independent space, makes motor plus fan blade
Overall structure space-consuming is than larger, and overall weight is bigger than normal.
Utility model content
The utility model purpose is：Aim to provide the cramped construction of outer rotor air duct brushless electric machine so that motor and fan blade
Overall space take and be greatly reduced, with miniaturization, light-weighted feature, use more comfortable and convenient.
To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
The cramped construction of outer rotor air duct brushless electric machine, including the first axle center, first axle center left end are connected with copper sheathing,
The copper sheathing is externally connected with the first fan blade, and the first fan blade right-hand member offers in circular trough, the circular trough and is arranged with first
The first magnet steel is arranged with magnetic guiding loop, first magnetic guiding loop, first axle center right-hand member is connected with bearing holder (housing, cover), the bearing holder (housing, cover)
It is externally connected with support.
Using the utility model of the technical program, offered in the first fan blade right-hand member and first is pasted in circular trough, circular trough
Magnetic guiding loop and the first magnet steel, the first fan blade and the first magnetic guiding loop or the first magnetic guiding loop and the first magnet steel are matched somebody with somebody using pine, this
The right-hand member of the fan blade of sample first has acted as the effect of motor case, reduces overall structure space, is greatly reduced inside air duct
Space.Traditional motor adds in the structure of fan blade, and the second axle center left end connects connection casing in the middle part of the second fan blade, the second axle center,
The second magnetic guiding loop and the second magnet steel are arranged in casing.The technical program is compared with traditional motor adds the scheme of fan blade, and space subtracts
Lack 20% or so.Such structure design so that the overall space of motor and fan blade takes and is greatly reduced, with small-sized
Change, light-weighted feature, are used more comfortable and convenient.
Further limit, first fan blade is antecurvature formula fan blade.Such structure design, can reduce the first fan blade
External diameter, reduces the volume of motor, mitigates the weight of motor.
Further limit, first fan blade is plastic structure.Such structure design, further mitigates the first fan blade
Weight.
Further limit, first magnet steel is Nd-Fe-B magnet steel.Such structure design, magnetic is high, and performance is good.
Further limit, the quantity of the first fan blade blade is nine.Such structure design, good heat dissipation effect.
