Description

A kind of circle motor

Technical field

The utility model relates to a kind of round motors comprising stator module, rotor and end cap.

Background technique

During motor production and processing, the structure of motor is by stator, and rotor and end cap three parts form, and motor The positioning datum of the assembly of structure is determined by the cooperation of stator and end cap, however in the design of round motor, according to normal Square motor production is advised, motor location structure is complicated, and processing technology and assembly technology difficulty are higher, and appearance is also undesirable.

Summary of the invention

For the problems of above-mentioned prior art, the purpose of the utility model is to provide a kind of positioning accuracy height and dresses With round motor with high accuracy.

In order to achieve the above objectives, the technical scheme adopted by the utility model is

A kind of circle motor, including stator module, rotor and end cap, the stator module include shell and are fixed on outer Iron core in shell, the iron core are close to outer casing inner wall, the end cap and cage connection.

Preferably, the shell is circular housing.

Preferably, the iron core and shell are integral by glue curing.

The beneficial effects of the utility model are: the stationary part of the circle motor includes shell and iron core, conventional motor Stationary part is only made of iron core, and conventional motor uses stator and end cap to cooperate positioning, due to being rectangular, appearance four sides Neatly can, if round motor directly uses circular stator and end cap directly to position, since the anchor point of stator does not have Precision Machining processing, assembly precision and positioning accuracy are lower, cause the precision of motor also to reduce, therefore the utility model is determined Subdivision uses form of the shell in conjunction with iron core, and shell is handled by finishing, is connected thereto end cap, to improve assembly Precision and positioning accuracy, in motor assembling process, qualification rate is improved, and the operating accuracy of motor has bigger improvement.

The utility model is described in further detail with reference to the accompanying drawings and examples.

Detailed description of the invention

It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Obtain other attached drawings.

Fig. 1 is a kind of structural schematic diagram of circle motor in the embodiments of the present invention.

Fig. 2 is the assembly positioning schematic diagram without the round motor of shell.

Fig. 3 is the assembly positioning schematic diagram of conventional motor.

Specific embodiment

To keep the purpose of this utility model, technical solution and advantage clearer, elaborated below with specific embodiment The more technical details of the utility model.

As shown in figure 3, conventional motor includes stator, rotor and end cap, stationary part is only made of iron core, conventional motor Use square shaped stator and end cap to cooperate positioning, due to be it is rectangular, appearance four sides neatly can, 101 in Fig. 3 are Conventional motor anchor point is the positioning datum of end cap and square shaped stator, as shown in Fig. 2, if round motor is directly using circle Shape stator and end cap directly position, and it is the positioning datum of end cap and stator that 201 in Fig. 2, which are round motor anchor point, by There is no Precision Machining processing in the anchor point of stator, assembly precision and positioning accuracy are lower, and cause the precision of motor that can also reduce, In terms of appearance, since stationary part outer diameter is less than normal, motor appearance appears not to be an entirety, influences appearance requirement, therefore need There is an accessory to come connecting stator, while the structure that can also be positioned with end cap, as shown in Figure 1, the round motor of the present embodiment, Including stator module, rotor 2 and end cap 3, stator module includes shell 11 and the iron core being fixed in shell 11 12, shell 11 be circular housing, and iron core 12 is close to 11 inner wall of shell, and then plus special anaerobism glue is fixed, and makes glue by heating The firmness for increasing shell 11 and iron core 12 is fully cured in water, forms it into whole, a stationary part use of the present embodiment The form that shell 11 is combined with iron core 12, shell 11 are handled by finishing, are connected thereto end cap 3, and 111 be this in Fig. 1 The anchor point of the round motor of embodiment is the positioning datum of end cap and stator module, and it is fixed to be cooperated using shell 11 and end cap 3 Position, to improve assembly precision and positioning accuracy, in motor assembling process, assembly manipulation is simpler, and qualification rate improves, motor Operating accuracy have bigger improvement,

Although the utility model is to be described with reference to specific embodiments, this description is not meant to the utility model It is construed as limiting.Referring to the description of the utility model, other variations of the disclosed embodiments are all for those skilled in the art It is anticipated that, such variation should belong in appended claims limited range.
