Description
Technical field
The utility model relates to a kind of motor stamping, relates more specifically to a kind of industrial ceiling fan AC permanent magnet synchronous motor stator punching.Be applicable to the industrial ceiling fan of industrial ceiling fan espespecially low-speed big, belong to electric motors.
Background technology
The feature of large scale industry ceiling fan is that rotating speed is low, and moment of torsion is large, and therefore existing general-purpose machine is due to the restriction of stator punching, cannot this type of ceiling fan of Direct driver, needs to be equipped with corresponding deceleration device.This just makes industrial ceiling fan there is the shortcomings such as volume is large, weight is large, efficiency is low.
Therefore, be necessary to provide a kind of have high-energy conversion efficiency, can the motor stator punching of Direct driver industrial ceiling fan.
Summary of the invention
The utility model discloses a kind of industrial ceiling fan AC permanent magnet synchronous motor stator punching, aim to provide a kind of structure simple, the industrial ceiling fan AC permanent magnet synchronous motor stator punching that power density is high, makes electric efficiency improve, without the need to installing decelerator.
For reaching above object, the technical scheme that the utility model is taked is:
A kind of industrial ceiling fan AC permanent magnet synchronous motor stator punching, comprise teeth portion, yoke portion, boots portion and winding slot, wherein the external diameter of stator punching and the ratio of internal diameter are 1.255 ± 0.005;
The ratio of teeth portion width and yoke portion thickness is (6.4 ~ 6.6): (3.4 ~ 3.6), and namely teeth portion width is 1.857 ± 0.081 times of yoke portion thickness; Boots portion thickness is 1mm ± 0.005; The quantity of winding slot is 63.
As preferably,
The ratio of teeth portion width and yoke portion thickness is 6.5:3.5, and namely teeth portion width is 1.857 times of yoke portion thickness;
The external diameter of stator punching and the ratio of internal diameter are 1.255;
Boots portion thickness is 1mm.
Industrial ceiling fan AC permanent magnet synchronous motor described in the utility model punching, owing to adopting JMAG analysis software, utilize the groove number principle that more multi-energy density is higher, by finite element optimization method determine and each critical size optimized, the energy conversion efficiency of motor can be improved, make motor in unit volume situation, significantly reduce the wastage, experiment shows, the industrial ceiling fan of equal-wattage, adopts the utility model, volume reduces 1/2nd, weight saving 1/3rd, operational efficiency can improve 3 ~ 4 percentage points, and without the need to configuring decelerator.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
Figure acceptance of the bid score not Biao Shi: 1-teeth portion, 2-yoke portion, 3-winding slot, 4-boots portion, A-stator outer diameter, B-diameter of stator bore, C-teeth portion width, D-yoke portion thickness, E-oblique angle, boots portion, F-boots portion thickness.
Embodiment
Below, by reference to the accompanying drawings and most preferred embodiment, be further described.
As shown in Figure 1, industrial ceiling fan AC permanent magnet synchronous motor punching, comprise: teeth portion 1, yoke portion 2, winding slot 3, boots portion 4, by application finite element optimization method, for stator punching outer diameter A, the ratio of internal diameter B, the ratio of stator teeth width C and yoke portion thickness D, the thickness of stator boots portion E has carried out simulation calculation, and make model machine and verify, in preferred version of the present utility model, described critical size is: stator outer diameter/diameter of stator bore=A/B=270/215=1.255, simultaneously, teeth portion width/yoke portion thickness=C/D=6.5/3.5=1.857, namely stator teeth width shown in is 1.857 times of yoke portion thickness, stator boots portion thickness E=1mm.
Industrial ceiling fan AC permanent magnet synchronous motor described in the utility model punching, by finite element optimization method determine and each critical size optimized, the energy conversion efficiency of motor can be improved, make motor in unit volume situation, significantly reduce the wastage, make industrial ceiling fan under equal-wattage, volume reduces 1/2nd, weight saving 1/3rd, operational efficiency can improve 3 ~ 4 percentage points, and without the need to configuring decelerator.
The foregoing is only better possible embodiments of the present utility model, not thereby limit to the scope of the claims of the present utility model, therefore the equivalent structure change that every utilization the utility model specification and accompanying drawing content are done, be all contained in protection range of the present utility model.
