Description

Technical Field

[0001] This application relates to the technical field of motor stators, specifically to stator windings for motors. Background Art

[0002] A motor is an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. Its main function is to generate a driving torque. As a power source for electrical appliances or various machines, a motor mainly consists of a stator structure, a rotor structure, and a housing.

[0003] During the use of a motor, in order to ensure the normal operation of the motor, a stator winding needs to be set up to generate a magnetic field and interact with the rotor magnetic field, thereby generating an electromagnetic torque to enable the motor to operate.

[0004] For example, the patent with the publication number CN219740068U specifically discloses a motor stator winding structure. This structure winds multiple groups of copper wires on a winding block, and then a detachable baffle is set at one end of the winding block to ensure that after the stator winding is damaged, the baffle can be disassembled for maintenance.

[0005] However, during the implementation of the above patent, since the winding block is an integral part, in the production of the stator winding, the winding block is produced by an integral mold, and the number of winding teeth is fixed. When assembling the motor, since the internal space of each motor housing is different, the number of winding groups on the winding block also needs to be different during motor assembly to facilitate the installation of the stator winding. Therefore, multiple integral molds need to be used for manufacturing, which increases the usage cost for users.

[0006] Therefore, it is necessary to provide a stator winding for a motor to solve the above problems.

[0007] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

[0008] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide a stator winding for a motor to achieve the effect of being able to adjust the number of winding teeth.

[0009] The technical solution adopted by this application to solve its technical problems is: a stator winding for a motor, including a housing; a winding structure, which is arranged on the housing and is suitable for generating a magnetic field; a connection structure, which is installed inside the housing and is suitable for connecting the winding structure and the housing. The connection structure includes: a limiting part, which is installed on the winding structure; a fixing part, which is installed inside the housing, and a groove is opened inside the fixing part, and a nut is arranged inside the groove.

[0010] Further, the winding structure includes at least two groups of winding teeth arranged along the circumferential direction of the housing, and winding wires are arranged on the winding teeth. The material of the winding wires is a metal material.

[0011] Further, an isolation structure is provided on the housing.

[0012] Further, the isolation structure includes an insulating elastic pad arranged on the outer peripheral surface of the housing.

[0013] Further, at least two groups of socket holes are formed in the insulating elastic pad along the circumferential direction.

[0014] The beneficial effect of the present application is that for the stator winding for a motor provided by the present application, the number of winding teeth can be increased or decreased through the connection assembly, so as to change the space occupied by the winding structure inside the motor housing. Therefore, when facing motor housings with different internal spaces, the number of winding teeth can be adjusted according to the internal space of the motor housing, so as to be more convenient and fast when installing the stator winding, achieving the effect of being able to adjust the number of winding teeth.

[0015] In addition to the purposes, features and advantages described above, the present application has other purposes, features and advantages. The following will refer to the drawings to make a further detailed description of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0025] As Figure 1 - Figure 2 shown, the present application provides a stator winding for a motor, including a housing 1, on which a winding structure 2 is provided. The winding structure 2 is used to generate a magnetic field to cooperate with the rotor magnetic field to drive the motor to rotate. At the same time, a connection structure 3 is provided inside the housing 1. The connection structure 3 is used to connect the winding structure 2. Specifically:

[0026] As Figure 1 shown, the winding structure 2 includes a plurality of winding teeth 21 arranged along the circumferential direction of the housing 1. At the same time, a winding wire 22 is provided on the winding teeth 21. The material of the winding wire 22 is a metal material, such as copper wire, aluminum wire, copper alloy wire, and copper strip, etc., so as to generate a magnetic field after being energized;

[0027] As Figure 2 - Figure 3 shown, the connection structure 3 includes a limiting portion 31 fixedly installed at the bottom of the winding teeth 21, and a fixing portion 32 fixedly installed inside the housing 1. The fixing portion 32 has a groove adapted to the limiting portion 31 to facilitate the insertion of the limiting portion 31;

[0028] At the same time, a nut is integrally formed in the groove, and a through hole is provided on the winding teeth 21. Thus, a bolt can pass through the through hole and be installed with the nut, and then the winding teeth 21 can be fixed on the housing 1. When disassembly is required, only the bolt needs to be unscrewed;

[0029] In summary, when facing different motor assemblies, due to the different spaces inside the motor housing, in order to facilitate the installation of the stator winding, the number of winding teeth 21 can be increased or decreased.

[0030] In order to increase the tightness when the winding teeth 21 are installed on the housing 1, as Figure 2 - Figure 3As shown in the figure, an isolation structure 4 is provided on the outer ring of the housing 1. The isolation structure 4 includes an insulating elastic pad 41 provided on the outer peripheral surface of the housing 1. At the same time, a plurality of sets of socket holes 42 adapted to the limiting portion 31 are provided in the circumferential direction on the insulating elastic pad 41. The socket holes 42 are used for the insertion of the limiting portion 31 and ensure the integrity of the insulating elastic pad 41 when not inserted. It should be noted that the socket holes 42 cut the insulating elastic pad 41 into a cross shape in the socket area to facilitate maintaining the integrity of the insulating elastic pad 41 when the limiting portion 31 is not inserted.

[0031] When installing the winding tooth 21, the insulating elastic pad 41 is sleeved on the outside of the housing 1, and then the limiting portion 31 is inserted into the socket hole 42. The winding tooth 21 and the housing 1 are connected through the connecting structure 3. At this time, the insulating elastic pad 41 will abut against the winding tooth 21 and cover the connecting structure 3 to support the winding tooth 21.

[0032] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
