[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1-Figure 5As shown, the utility model is a simple teaching device for simulating the offline operation of an electric motor, comprising a ring-shaped offline wire drum 1 made of transparent acrylic material, at least six wire insertion grooves 2 are provided at the top of the offline wire drum 1 along the circumferential direction, the wire insertion grooves 2 are equidistantly distributed along the circumferential direction and are connected to the inner side of the offline wire drum 1 through a constriction 3 provided on one side, at least three ring-shaped plug-in coils 4 are provided on the inner side of the offline wire drum 1, both sides of the plug-in coil 4 are respectively limitedly plugged into the wire insertion grooves 2 and the multiple plug-in coils 4 are staggered.

[0022] Among them, the plug-in coil 4 includes a flexible rubber tube 41 with a hollow interior, and a heat shrink sleeve 42 is sleeved on both ends of the flexible rubber tube 41. The flexible rubber tube 41 is connected to the heat shrink sleeve 42 to form a ring-shaped plug-in coil 4, and solid connecting pins 43 are inserted into the interior of both ends of the flexible rubber tube 41.

[0023] In detail, the flexible rubber tube 41 can be cut according to the actual length requirement, and then the two connecting pins 43 are respectively inserted into the two ends of the flexible rubber tube 41. Through the setting of the connecting pins 43, the two ends of the flexible rubber tube 41 can be conveniently inserted into the heat shrink sleeve 42, and then the heat shrink sleeve 42 is baked by a baking lamp or heating equipment. In this way, the heat shrink sleeve 42 can be tightly connected to the flexible rubber tube 41. Through the flexible characteristics of the flexible rubber tube 41, it can be inserted into the wire socket 2 more easily and smoothly.

[0024] Among them, there are an even number of wire slots 2, and the number of wire slots 2 is twice that of plug-in coils 4, because when a plug-in coil 4 is inserted into the wire slots 2 on both sides, two corresponding wire slots 2 are required. In this way, the number of wire slots 2 required is twice that of plug-in coils 4. The number of plug-in coils 4 can be selected according to actual needs, 3 or 6 or 9 or 12, which can be a multiple of 3, and then a matching lower wire reel 1 with corresponding wire slots 2 is produced.

[0025] The width of the constriction 3 is smaller than the outer diameter of the plug-in coil 4. By setting the constriction 3, the plug-in coil 4 inserted into the wire slot 2 can be limited to prevent the plug-in coil 4 from falling off after insertion.

[0026] The lower wire drum 1 is made of transparent acrylic material with a thickness of 2-5 cm. By making the lower wire drum 1 of transparent acrylic material, it is convenient for the user to observe the plug-in coil 4 inserted into the plug-in slot 2 to check whether there is an error in the plug-in position.

[0027] Working principle: The winding inner cavity of the motor coil is simulated by the down-line reel 1, and the annular coil inside the motor is simulated by the plug-in coil 4. When the coil is actually down-line installed, due to the large number of coils inside the motor and the need to cross-displace different coils according to the use principle of the motor, when students plug and install the coils and motors in the laboratory, it is easy to cross inaccurately because the coils are of the same size and the operation is unskilled, and the wrong position cannot be intuitively seen, which brings great trouble to the students. Through the setting of the teaching device, different colors of flexible rubber tubes 41 can be used to make different colors. Plug-in coil 4, and then simulate the connection between the actual coil and the motor chamber by connecting the plug-in coil 4 with the lower line disk 1. The insertion position of each plug-in coil 4 can be intuitively seen through the color distinction, and the crossing position between the plug-in coils 4 of different colors can also be intuitively viewed. In this way, after the students have practiced proficiently through the teaching simulation device, they can intuitively learn the chain and concentric lowering methods, and can more easily perform the operation of connecting the actual coil with the motor chamber. The overall structure of the simulation teaching device is relatively simple, and the materials can be easily obtained. This can reduce the teaching cost while achieving a good teaching purpose for the students.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
