Description
Technical field：
The utility model is related to a kind of heat dissipation rotor field spider structures of magneto.
Background technology：
The rotor body being presently used on the motor partly directly driven does not have the effect of centrifugal fan, is unfavorable for motor heat
Distribute, cause motor temperature rise high, influence motor service life.
Therefore, it is necessory to be improved to the prior art to solve the deficiency of the prior art.
Utility model content：
The utility model is to provide a kind of heat dissipation of magneto turn to solve the above-mentioned problems of the prior art
Submounts structure.
Technical solution used by the utility model has：A kind of heat dissipation rotor field spider structure of magneto, including inner cylinder,
Outer barrel, mounting bracket, the first fan blade and the second fan blade, inner barrel and outer barrel coaxial arrangement, and inner barrel and outer barrel it
Between be formed with installation cavity, several mounting brackets are distributed in along the circumferencial direction of inner cylinder in installation cavity, and one end of mounting bracket with it is outer
The inner wall of cylinder is fixedly connected, and the other end is fixedly connected with the outer wall of inner cylinder, and second fan leaf is fixed in each mounting bracket
Piece symmetrically fixes two the first fan blade on the outer wall of each mounting bracket.
Further, the cross section of the mounting bracket is U-shape.
Further, the outer circle wall of the inner cylinder is equipped with groove.
Further, the mounting bracket is equipped with several heat emission holes, and the axis of the heat emission hole is parallel with the axis of inner cylinder.
The utility model has the advantages that：The utility model is used for permanent magnet machine rotor, simple in structure, thermal diffusivity
Can be good, easy for installation, manufacturing cost is low, and service life is long.
Description of the drawings：
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model application structure figure.
Specific implementation mode：
The utility model will be further described below with reference to the accompanying drawings.
As depicted in figs. 1 and 2, the utility model discloses a kind of heat dissipation rotor field spider structure of magneto, including inner cylinder
1, outer barrel 2, mounting bracket 3, the first fan blade 4 and the second fan blade 5, inner cylinder 1 and outer barrel 2 are coaxially disposed, and inner cylinder 1 and outer
It is formed with installation cavity 10 between cylinder 2, several mounting brackets 3 are distributed in along the circumferencial direction of inner cylinder 1 in installation cavity 10, and mounting bracket
3 one end is fixedly connected with the inner wall of outer barrel 2, and the other end is fixedly connected with the outer wall of inner cylinder 1, fixed in each mounting bracket 3
One the second fan blade 5 symmetrically fixes two the first fan blade 4 on the outer wall of each mounting bracket 3.
The cross section of mounting bracket 3 is U-shape.3 Open architecture of mounting bracket dissipate while ensureing structural stability
Thermal effect is good.
Several heat emission holes are equipped on mounting bracket 3, the axis of the heat emission hole is parallel with the axis of inner cylinder 1 (not to be drawn in figure
Go out).
Groove 11 is equipped on the outer circle wall of inner cylinder 1.Groove 11 can mitigate overall weight, and be dispersed convenient for heat.
In use, rotor 200 is fixed in inner cylinder 1, permanent magnet 100 is fixed on the outer wall of outer barrel 2.The utility model is just
In heat dissipation, since motor is in normal operation, motor generates a large amount of heat so that motor internal temperature rises, if do not had
The radiator structure of effect, the service life for being bound to cause motor shorten significantly.Mounting bracket 3 in the utility model has logical well
The effect of wind heat dissipation, after the motor equipped with the rotor field spider rotates, the first fan blade 4 and the second fan blade 5
So that turn over submounts are provided with the effect of centrifugal fan so that the thermal convection current aggravation conduction inside motor is set on mounting bracket 3
There are several heat emission holes, heat emission hole effectively provides channel for thermal convection current, therefore motor internal heat will be quickly by external cold
But device is taken away so that motor temperature rise reduces, to which the quality of motor be effectively ensured.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The scope of protection of the utility model.
