Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] Example 1:

[0040] This embodiment provides a motor stator, including:

[0041] Protective housing;

[0042] The composite iron core is housed within the protective casing.

[0043] As can be seen from this embodiment, the protective shell is disposed on the outside of the composite iron core;

[0044] The modular iron core can be protected during use, making the stator less susceptible to external influences. At the same time, the modular iron core is easy to assemble with the protective shell, which helps to improve assembly efficiency.

[0045] Example 2:

[0046] This embodiment provides a motor stator, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] The protective housing includes:

[0048] A fixed frame 11 has a first connecting edge 111 formed on one side, a first thread formed on the inner wall of the first connecting edge 111, and threaded holes 112 arranged in a circumferential array on the fixed frame 11. A first port 113 is provided on the end face of the fixed frame 11 inside the threaded holes 112.

[0049] The protective shell 12 has a second port 121 on one end face and the other end of the protective shell 12 is open and has a connecting end 122, and the connecting end 122 has a second thread.

[0050] The composite iron core is set inside the protective shell 12 and connected to the threaded hole 112, with a gap formed between the composite iron core and the protective shell 12.

[0051] As can be seen from this embodiment, the protective housing includes a fixing frame 11 and a protective shell 12;

[0052] A first connecting edge 111 is formed on the edge of one end face of the fixed frame 11, and a first thread is formed on the inner wall of the first connecting edge 111 for connecting the protective shell 12.

[0053] Furthermore, the fixed frame 11 has a threaded hole 112 formed on the end face inside the first connecting edge 111 for installing the combined iron core, and the fixed frame 11 has a first port 113 formed on the end face inside the threaded hole 112, which is used to allow the rotor to pass through during use.

[0054] One end of the protective shell 12 is formed with a second port 121, which is in a constricted shape. The other end of the protective shell 12 is formed with a stepped connecting end 122. A second thread is formed on the outer wall of the connecting end 122. The second thread cooperates with the first connecting thread to detachably assemble the connecting end 122 and the first connecting edge 111 together.

[0055] The combined iron core is installed in the threaded hole 112 and is located within the protective shell 12. The protective shell 12 and the fixing frame 11 are detachably fixed together through the threaded engagement between the connecting end 122 and the first connecting edge 111, which facilitates the installation of the combined iron core. At the same time, the protective shell is located outside the iron core to protect it. Furthermore, there is a gap formed between the combined iron core and the protective shell, so the combined iron core does not directly contact the protective shell, thereby avoiding direct participation in the stress and helping to improve the protective effect.

[0056] Example 3:

[0057] This embodiment provides a motor stator, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0058] The composite iron core includes:

[0059] Connecting rod 21, one end of which is provided with threaded section 211, and is connected to threaded hole 112 and assembled onto fixed frame 11 through threaded section 211; the other end of connecting rod 21 extends into protective shell 12.

[0060] The iron core body 22 has a connection hole 221. The iron core body 22 is tightly connected to one end of the connecting rod 21 inside the protective shell through the connection hole 221.

[0061] Among them, the iron core body 22 has a fan-shaped cross section, and multiple iron core bodies 22 are connected to multiple connecting rods 21 to form a ring conductor;

[0062] The connecting rod 21 has one end protruding to form a connector 212, and a connector 23 is connected to the connector 212. A through groove 114 is provided on the side wall of the fixed frame 11, and the connector 23 extends from the through groove 114 to the outside of the fixed frame 11.

[0063] As can be seen from this embodiment, the combined iron core includes a connecting rod 21 and an iron core body 22;

[0064] The connecting rod 21 has a threaded section 211 formed on it. The connecting rod 21 is connected to the threaded hole 112 through the threaded section 211 and then assembled onto the fixing frame 11. The other end of the connecting rod 21 is located inside the first connecting edge 111 and is wrapped inside the protective shell 12 after the protective shell 12 is connected to the first connecting edge 111. The connection between the connecting rod 21 and the fixing frame 11 is simple and reliable. The connecting rod 21 is limited and fixed inside the protective shell 12 through the threaded engagement with the threaded hole 112. This helps to control the gap between the iron core body 22 and the protective shell 12 by adjusting the size of the iron core body 22 (the attached figure is only a schematic diagram of one type of gap, and the specific gap size can be set according to actual needs).

[0065] Furthermore, a power connector 212 is formed on the end face of the threaded section 211 on the outside of the fixed frame 11. A power connector 23 is connected to the power connector 212. The power connector 23 is in direct contact with the power connector 212 and the end face of the threaded section 211 on the outside of the fixed frame 11, and supplies power after the power is connected.

[0066] Furthermore, a through groove 114 is formed on the wall surface of the fixed frame 11. By setting the through groove 114 on the wall surface of the fixed frame 11, it is convenient for the electrical connector 23 to be connected to an external power source, thereby achieving the effect of power supply.

[0067] The iron core body 22 is fan-shaped, and a connecting hole 221 is formed in the center of the iron core body 22. The connecting hole 221 and the connecting rod 21 are tightly connected to achieve fixation. After multiple iron core bodies 22 are connected to multiple connecting rods 21, a ring-shaped conductor is formed. When in use, after the connecting rod 21 is energized through the energizing component 23, the iron core body 22 is synchronously energized to form an electromagnetic field.

[0073] The power connector 23 is connected to the power connector 212 through the through hole 231 and assembled to one side of the fixed frame 11. At the same time, the connecting ear 232 extends from the through groove 114 to the outside of the fixed frame 11 and connects to the power supply. The power connector 23 is made of pure copper, which helps to improve the conductivity efficiency.
