Description

Technical Field

[0001] This utility model belongs to the field of stator technology, and in particular relates to a multi-segment wound motor stator. Background Technology

[0002] In simple terms: the stationary part of a motor is called the stator, on which a pair of DC-excited stationary main magnetic poles are installed; while the rotating part, the rotor, is called the armature core, on which armature windings are installed. When energized, it generates an induced electromotive force, which acts as a rotating magnetic field. This then produces electromagnetic torque for energy conversion. The stator is distinguished by the shape and mounting method of the stator windings.

[0003] In the existing stator production process, the winding structure of different stators is limited, which often requires the use of different equipment for the coil winding process. This can easily increase the production cost and reduce the company's profits. Therefore, we have specially designed a multi-segment wound motor stator. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a multi-segment wound motor stator that facilitates winding.

[0005] In view of this, the present invention provides a multi-segment wound motor stator, comprising:

[0006] The frame has connection slots.

[0007] The winding frame includes a connecting frame and a wire bundle frame. The connecting frame is set in the connecting groove, and the wire bundle frame extends to the inside of the frame.

[0008] The coil is mounted on the wire harness frame.

[0009] Furthermore, the above technical solution also includes:

[0010] Fixed covers are installed on both sides of the frame and seal the connecting grooves;

[0011] The frame has connecting ends on both sides, and the fixing cover is threaded to the connecting ends.

[0012] Furthermore, the above technical solution also includes:

[0013] The first fixing frame is disposed between the frame and the fixing cover. The first fixing frame is provided with a fixing protrusion that corresponds to the connecting groove.

[0014] The connecting frame has connecting holes formed on both sides, and the connecting holes are tightly connected to the fixing protrusions.

[0015] Furthermore, the above technical solution also includes:

[0016] An arched frame with a connecting plate that connects to the cable tie frame.

[0017] Furthermore, the above technical solution also includes:

[0018] The connecting frame is set on the cable tie frame and has a slot that fits tightly with the connecting plate for fixation.

[0019] Furthermore, the above technical solution also includes:

[0020] The second fixing frame is located between the first fixing frame and the fixing cover, and extends to both sides of the cable tie frame and the arched frame.

[0021] Furthermore, the above technical solution also includes:

[0023] Furthermore, the above technical solution also includes:

[0024] The pad includes a first pad and a second pad, the first pad being disposed between the first fixing bracket and the frame, and the second pad being disposed between the second fixing bracket and the fixing cover.

[0025] The beneficial effects of this utility model are as follows: the winding frame and the frame are detachably connected, thereby achieving the effect of subcontracted assembly. Compared with the traditional one-piece molded stator structure with wire groove, the influence of the processing technology changes brought about by the stator structure during the winding of the coil is small, which helps to improve production efficiency and the scope of application.

The connecting frame 21 is tightly connected to the connecting groove 11 and then fixed to the frame 1. The wire bundle frame 22 is located inside the frame 1 and is wound with coils 3.

[0039] The winding frame 2 and the frame 1 are detachably connected, thus achieving the effect of subcontracted assembly. Compared with the traditional one-piece molded stator structure with wire groove, the winding coil 3 is less affected by the changes in processing technology caused by the stator structure, which helps to improve production efficiency and application range.

[0040] Example 2:

[0041] This embodiment provides a multi-segment wound motor stator, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0042] Fixed cover 4 is provided on both sides of frame 1 and closes the connecting groove 11;

[0043] The frame 1 has connecting ends 12 on both sides, and the fixed cover 4 is threadedly connected to the connecting ends 12.

[0044] As can be seen from this embodiment, the frame 1 has connecting ends 12 formed at both ends, and fixed covers 4 are threadedly connected to them;

[0045] After the winding frame 2 and the connecting groove 11 are assembled, the fixing cover 4 further limits the winding frame 2, thereby making the connection between the winding frame 2 and the frame 1 stable.

[0046] Example 3:

[0047] This embodiment provides a multi-segment wound motor stator, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0048] The first fixing frame 5 is disposed between the frame 1 and the fixing cover 4. The first fixing frame 5 is provided with a fixing protrusion 51, which corresponds to the connecting groove 11.

[0049] The connecting frame 21 has connecting holes 211 formed on both sides, and the connecting holes 211 are tightly connected to the fixing protrusion 51.

[0050] As can be seen from this embodiment, the first fixing frame 5 is installed between the frame 1 and the fixing cover 4 and is located inside the connecting end 12. The first fixing frame 5 has fixing protrusions 51 spaced apart from the connecting groove 11, while the connecting frame body 21 has connecting holes 211 formed on it.

[0051] In use, the first fixing bracket 5 is assembled to both sides of the frame 1 through the fixing protrusion 51 and the connecting hole 211, and is limited and fixed to the frame 1 after the fixing cover 4 is connected to the connecting end 12.

[0052] By setting the first fixing frame 5, the structural strength of the winding frame 2 in the frame 1 can be further enhanced.

[0053] Example 4:

[0054] This embodiment provides a multi-segment wound motor stator, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] An arched frame 6 is provided with a connecting plate 61, which is connected to the cable tie frame 22.

[0056] As can be seen from this embodiment, a connecting plate 61 is formed on the arched frame 6. The connecting plate 61 is connected to the wire harness frame 22. When in use, after multiple wire harness frames 2 are connected to the frame 1, the arched frames 6 on adjacent wire harness frames 2 abut against each other and form a protective structure inside the frame 1. The arched fit between adjacent arched frames 6 helps to improve the structural strength.

[0057] The winding frame 2 and coil 3 can be protected during use, which helps to extend their service life.

[0058] Example 5:

[0059] This embodiment provides a multi-segment wound motor stator, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0060] The connecting frame 21 is mounted on the cable tie frame 22. The connecting frame 222 is provided with a slot 2221, which is tightly fitted and fixed to the connecting plate 61.

[0061] As can be seen in this embodiment, the connecting frame 21 is formed on the side wall of the cable tie frame 22 facing the center of the frame 1. The connecting frame 222 has a slot 2221 formed on it. After the connecting plate 61 is tightly connected to the slot 2221, the arched frame 6 is fixed to the cable tie frame 22.

[0062] The connection frame 222 facilitates the assembly of the arched frame 6 and the cable tie frame 22. The connection between the arched frame 6 and the cable tie frame 22 is simple and easy to assemble.

[0063] Example 6:

[0064] This embodiment provides a multi-segment wound motor stator, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0065] The second fixing frame 7 is disposed between the first fixing frame 5 and the fixing cover 4, and extends to both sides of the cable tie frame 22 and the arched frame 6.

[0066] As can be seen from this embodiment, the second fixing frame 7 is located outside the first fixing frame 5, and is fixed to the frame 1 after the fixing cover 4 is connected to the connecting end 12. The second fixing frame 7 is a ring plate.

[0067] When in use, the second fixing frame 7 can limit the arch frame 6 to prevent the arch frame 6 from sliding and affecting its use.

[0068] Example 7:

[0069] This embodiment provides a multi-segment wound motor stator, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0070] Amplification protrusion 8 is located inside the arched frame and abuts against coil 3.

[0071] As can be seen from this embodiment, the arched frame 6 is made of conductive material, and the inner wall of the arched frame 6 is formed with amplification protrusions 8. The amplification protrusions 8 directly contact the coils 3 on the winding wire harness frame, so that multiple arched frames 6 form an electromagnet inside the frame 1, which can effectively improve the slot fill rate and thus improve the stator magnetic effect during use.
