Abstract
The utility model provides an end cover of an asynchronous motor, and pertains to the technical field of motors, so as to solve the problems that components of the asynchronous motor in the prior art are poor in security and the synchronous motor takes up space. According to the end cover of the asynchronous motor, the end cover body is in a disc shape, and comprises a mounting groove, a groove wall and a flange from inside to outside; the center of the mounting groove is provided with a shaft hole; and one side of the groove wall is provided with a wire outlet path, the wire outlet path is communicated with the mounting groove, the other side of the groove wall is provided with a capacitor groove, and the capacitor groove is communicated with the mounting groove. The end cover of the asynchronous motor has the advantages that security of the components can be improved, and the space the asynchronous motor takes up can be saved.
Description
Technical field
The utility model belongs to technical field of motors, has related to a kind of asynchronous motor, has especially related to a kind of end cap of asynchronous motor.
Background technology
Along with progress and the expanding economy in epoch, motor as the motive use field more and more widely, asynchronous motor be most widely used in all kinds of motor, that requirement is maximum is a kind of.In China, the power consumption of asynchronous motor accounts for more than 60% of total load, generally is applied on the large industry equipment, and the high power epistasis of power can be stablized and obtained generally assert, for huge contribution has been made in economic development.
Housing top at asynchronous motor is typically provided with control box, is integrated with components and parts such as the control circuit of control asynchronous motor work and starting capacitance in this control box.The overall volume that has increased asynchronous motor is set like this, makes asynchronous motor occupy more space when mounted; Simultaneously, control box is arranged on housing top and is easy to cause control box to damage because of improper use, and the related components and parts that are arranged in the box also will be damaged when control box damages.
Summary of the invention
There are the problems referred to above in the utility model at existing technology, has proposed a kind of end cap of asynchronous motor, and this end cap can improve the fail safe of components and parts and have the advantage that takes up room of saving asynchronous motor.
The utility model is realized by following technical proposal: a kind of end cap of asynchronous motor, the body of described end cap is in the form of annular discs, this body comprises mounting groove, cell wall, rib from inside to outside, the center of described mounting groove has axis hole, it is characterized in that a side of described cell wall has out drawing lines, describedly go out drawing lines and be connected with mounting groove, the opposite side of described cell wall has the electric capacity groove, and described electric capacity groove is connected with mounting groove.In this end cap, mounting groove is used for the fixed electrical machinery rotating shaft; Going out the control cable that drawing lines is used for the power supply motivation passes; The electric capacity groove is used for fixed capacity.
In the end cap of above-mentioned a kind of asynchronous motor, have several bar holes on the described rib.Bar hole can make things convenient for airflow, has the effect that makes things convenient for the motor heat radiation.
In the end cap of above-mentioned a kind of asynchronous motor, the edge of described rib has several screws.Screw has the effect that makes things convenient for end cap and motor field frame to fix.
Compared with prior art, the end cap of this asynchronous motor comes for electric capacity is installed by offer the electric capacity groove at cell wall, and realize that by go out drawing lines motor field frame is connected with circuit between the end cap, and reduced the overall volume of asynchronous motor, saved taking up room of asynchronous motor; Simultaneously electric capacity and circuit are arranged in the end cap, have improved the security performance of components and parts.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, body; 2, mounting groove; 3, cell wall; 4, rib; 5, electric capacity groove; 6, go out drawing lines; 7, bar hole; 8, screw; 9, axis hole.
Embodiment
Below be specific embodiment of the utility model, and by reference to the accompanying drawings the technical solution of the utility model be further described, but the utility model is not limited to these embodiment.
The end cap of a kind of asynchronous motor as shown in Figure 1, the body 1 of described end cap is in the form of annular discs, this body 1 comprises mounting groove 2, cell wall 3, rib 4 from inside to outside, the center of described mounting groove 3 has axis hole 9, one side of described cell wall 3 has out drawing lines 6, describedly go out drawing lines 6 and be connected with mounting groove 2, the opposite side of described cell wall 3 has electric capacity groove 5, and described electric capacity groove 5 is connected with mounting groove 2.In this end cap, it is cylindric that mounting groove 2 generally is, and is generally used for the fixed electrical machinery rotating shaft; Go out drawing lines 6 and take the shape of the letter U, the control cable that is used for the power supply motivation passes; Electric capacity groove 5 shapes general and electric capacity are complementary, and are beneficial to better fixed capacity.
Airflow is convenient to the heat radiation of motor for convenience, has several bar holes 7 on the rib 4.In the present embodiment, the quantity of bar hole 7 is 3.End cap and motor field frame is fixing for convenience, and the edge of rib 4 has several screws 8, and in the present embodiment, the quantity of screw 8 is 4.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used body 1, mounting groove 2, cell wall 3, rib 4, electric capacity groove 5, gone out terms such as drawing lines 6, bar hole 7, screw 8, axis hole 9 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
