Abstract
The utility model relates to an improved-type ceiling fan motor, in particular to a technological improvement of fixed connection of a ceiling fan motor rotor and a bottom shell. The improved-type ceiling fan motor comprises a stator, a rotor, and an outer shell. The outer shell comprises an upper shell and a bottom shell. The side wall of the bottom shell is provided with a stair step. The rotor is fixed on the side wall, having a relatively small diameter, of the stair step through a rotor supporting column. The bottom wall of the inner cavity of the bottom shell is provided with a positioning concave part matched with the rotor supporting column. According to the utility model, the bottom shell of the conventional outer shell is processed into the bottom shell with the side wall having the stair step so that the mechanical strength of the bottom shell is relatively greatly improved and the bottom shell is not easy to deform; moreover, the bottom wall of the inner cavity of the bottom shell is provided with the positioning concave part matched with the rotor supporting column, and the rotor supporting column can be fitted and mounted on the positioning concave part, so that the operation stability of the fan motor is guaranteed and the mechanical strength of the ceiling fan motor is increased; and at the same time, by employing the stair step and the positioning concave part structures, rotor positioning column and other technologies are prevented from being added excessively and the production cost is effectively lowered.
Description
Technical field
The utility model relates to a kind of modified model ceiling fan motor, the technological improvement that particularly a kind of ceiling fan motor rotor is fixedly connected with drain pan.
Background technology
At present, common ceiling fan motor, its rotor is generally directly fixed in the base side walls of motor case by rotor supports post, and because existing base side walls is straight tube wall, mechanical strength is low, in transportation, installation and dismounting storing process, shell easily bumps with other object, and generation deformation, causes ceiling fan motor rotor and stator axiality poor, affect job stability, even make it scrap.In addition, because rotor is depended merely on the drain pan that rotor supports post is arranged on motor case, rotor supports post cannot effectively be located, and causes rotor easily to occur rocking displacement phenomenon, can cause equally the axiality skew of stator and rotor.In order to overcome this phenomenon, general producer adopts the quantity that increases rotor supports post, and itself and the drain pan of motor case being connected and fixed form multi-point support increases its mechanical strength, current common six to eight the such rotor supports posts that all need.Although adopt this structure to there is certain effect to improving the mechanical strength of motor case, but the deformation of shell easily causes rotor body and shell deformation together occurs, thereby affect the service behaviour of ceiling fan motor, on the other hand, increasing rotor supports post must increase the production cost of ceiling fan motor.
Summary of the invention
The deficiency that the utility model exists for prior art, designs the modified model ceiling fan motor that a kind of mechanical strength is high, Stability Analysis of Structures is difficult for displacement, production cost is low.
The purpose of this utility model is achieved in that a kind of modified model ceiling fan motor, comprise stator, rotor and shell, described shell comprises upper casing and drain pan, it is characterized in that: described base side walls is provided with ladder step, described rotor is fixed on by rotor supports post on the sidewall of described ladder step small diameter, has the location indentations matching with rotor supports post on the bottom wall of inner cavity of described drain pan.
Described rotor supports post is provided with the reference column being inserted in rotor.
Described rotor supports post is four, is 90 degree and is uniformly distributed.
Described rotor supports post is three, is 120 degree and is uniformly distributed.
Modified model ceiling fan motor described in the utility model is compared with existing ceiling fan motor, has following technological merit.
The base side walls of motor case of the present utility model is processed into the sidewall with ladder step by traditional straight tube wall, its mechanical strength is greatly improved, be difficult for occurring deformation, and on the bottom wall of inner cavity of drain pan, have the location indentations matching with rotor supports post, rotor supports post can match and be arranged in location indentations, thereby guaranteed the operation stability of fan motor, improve the mechanical strength of ceiling-fan motor, simultaneously, take ladder step and location indentations structure, avoid increasing too much the techniques such as rotor reference column, effectively reduce production costs.

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figures 1 to 5: ceiling fan motor described in the utility model, comprise stator, rotor and motor case, described motor case comprises upper casing and drain pan 1, drain pan 1 sidewall of described motor case is provided with ladder step 10, described rotor 2 is fixed on the sidewall of described ladder step 10 small diameters by rotor supports post 3, simultaneously, on the bottom wall of inner cavity of described drain pan 1, have the location indentations 4 matching with rotor supports post 3, rotor supports post 3 can match and be arranged in location indentations 4, as Fig. 3, shown in Fig. 4, and, described rotor supports post 3 is provided with the reference column 31 being inserted in rotor 2, as shown in Figure 2, guaranteed to be fixed together between rotor supports post 3 and rotor 2, during this time, rotor supports post 3 can be that split is welded.Because the utility model improves drain pan 1 structure division that technical scheme is only rotor 2 structures and ceiling fan motor casing, therefore drawing only provides this part-structure, other parts are omitted.From scheming, can find out, because drain pan 1 sidewall of motor case is provided with ladder step 10, the low problem of mechanical strength of its drain pan is effectively solved, and on the bottom wall of inner cavity of drain pan 1, have the location indentations 4 matching with rotor supports post 3, rotor supports post 3 can match and be arranged in location indentations 4, , as shown in Figure 5, thereby guaranteed the operation stability of fan motor, as long as thereby make being connected and fixed between ceiling fan motor rotor 2 and drain pan 1 establish four rotor supports posts 3, form even 90 degree distributions and just can guarantee its job stability, simple in structure, adopt relatively at present six to eight rotor supports posts 3, its cost is effectively controlled.Certainly, described rotor supports post 3 also can arrange 3, forms 120 degree and is evenly distributed on rotor 2, can reach and be connected and fixed stability equally.
