Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
For more accurate, describe in detail, in " upper and lower, left and right " described in following example and accompanying drawing " upper and lower,
Left and right " consistent.
Embodiment one: such as Fig. 1, a kind of unmanned plane brushless electric machine, including rotor 10, stator 20；Such as Fig. 2, Fig. 3, rotor 10
Including bottom 101 and axle portion 102, axle portion 102 is circle ring column, and bottom 101 is circular cylinder, and bottom 101 diameter is less than axle portion
Circular diameter in 102, is so connected between bottom 101 and axle portion 102 and is the formation of the space 103 of horizontal direction；Axle portion 102 is internal
For hollow and be provided with a permanent magnet 1021, rotor 10 is integrated with permanent magnet 1021, plays permanent magnet 1021 rotor driven 10
Rotary action；Bottom 101 upper surfaces are provided with boss 1012 and 12 diagonal bars 1011, and boss 1012 is circle ring column, is positioned at
101 upper surface central areas, bottom, diagonal bar 1011 is curve cube, is positioned at bottom 101 upper surface boss 1012 outer peripheral areas, bent
Facing left bending, 12 diagonal bars 1011 are equally spaced, and one end is connected with boss 1012 cylindrical wall, the other end and axle portion 102 port
Inner round wall is connected, and the height of diagonal bar 1011 is the most equal with boss 1012, so, between 12 diagonal bars 1011 with boss 1012 just
Defining 12 convulsion grooves 1014, rotor bottom 101 forms the structure of centrifugal fan, and bottom 101 is positioned at transverse plane in axle portion 102
On, it is connected to form the space 103 of vertical direction, such vertical direction space 103 and water between bottom 101 and 102, axle
Square form ramp type space 103 to space 103；Bottom 101 is additionally provided with 4 through boss 1012 and equidistant symmetrical through hole
1013, insert fixing for unmanned plane propeller screw rod；Such as Fig. 4, stator 20 center is provided with 1 axis hole 202, central periphery region
Being provided with 4 equidistant symmetries is hollow the 201 of fan.
During brushless electric machine work, rotor 10 rotates clockwise, and diagonal bar 1011 rotates and drives air from convulsion groove 1014 to tiltedly
Formula space, slope 103 is discharged, and outside motor air is entered in motor from stator 20 fan-shaped hollow 201 by motor internal suction draught simultaneously
Portion, the most whole motor is the formation of an extractor fan, passes air through motor and quickly flow, motor plays the effect of heat radiation
Really, make motor produced heat when working long hours rapid.
Embodiment two: such as Fig. 5, rotor bottom is provided with reverse diagonal bar 3011, and curved surface is towards the right side, and other are with embodiment one.
During brushless electric machine work, rotor rotates counterclockwise, and diagonal bar rotates and drives air to discharge to space from convulsion groove, simultaneously
Outside motor air is by motor internal suction draught from the fan-shaped hollow entrance motor internal of stator, and the most whole motor is the formation of one
Individual extractor fan, passes air through motor and quickly flows, and motor plays the effect of heat radiation, makes motor institute when working long hours
The heat produced is rapid.
In embodiments of the present invention, have the beneficial effects that by arranging 12 curved surfaces towards a left side or towards right bending in rotor bottom
CLB diagonal bar, boss formed 12 convulsion grooves, less than rotor shaft diameter by arranging rotor bottom diameter, rotor bottom
Higher than rotor shaft port plane between rotor bottom is connected with rotor shaft formed space, as convulsion export, by
4 sector hollow formation air inlets are set bottom stator, material is thus formed centrifugal fan structure, play acceleration air flowing,
Take away the radiating effect of motor heat.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection domain of the claims in the present invention
Within.
