This portion of the winding needs to be removed during subsequent processing, resulting in material waste.

[0024] When the number of stator teeth in the same phase group is greater than two
[0025] First, the winding machine is used to simultaneously wind the windings on both sides of the preset position onto the two stator teeth;
[0026] The remaining stator teeth in the same phase group are then wound using the winding machine to form a double-tailed winding.
[0027] In conjunction with the first aspect of this application, in an optional embodiment, the remaining stator teeth within the same phase group are wound using the winding machine to form the double-tailed winding, comprising:
[0028] When the number of remaining stator teeth in the phase group is even, the winding machine is used to simultaneously wind two stator teeth.

[0053] This invention provides a winding method for a double-tailed stator. The method involves cutting a preset length of wire, setting a preset position for the wire, fixing the preset position, and then using a winding machine to simultaneously wind the wire onto two stator teeth from both sides of the preset position, forming a double-tailed winding. The winding method provided by this application significantly reduces wire waste. Furthermore, when adjustments to the winding parameters are needed, the winding formed by this method is easy to disassemble, saving disassembly time.
[0054] like Figure 1 As shown, the double-tailed stator provided in this application embodiment firstly includes an iron core 10, the iron core 10 includes a stator yoke 11 and a plurality of stator teeth 12 surrounding the stator yoke, the stator teeth 12 being used for winding the wire.
[0055] The following describes a winding method for a double-tailed stator provided in an embodiment of this application, with reference to the accompanying drawings.
[0056] Specifically, such as Figure 2 As shown in the embodiment of this application, a winding method for a double-tailed stator includes the following steps:
[0057] S1. Group multiple stator teeth and form at least one phase group.
[0058] Phase groups correspond to the number of coil groups inside the motor. Commonly used stepper motors include two-phase, three-phase, four-phase, and five-phase motors. Different motors with different numbers of phases are selected according to different requirements.
[0059] In other words, before winding the stator teeth, multiple stator teeth are divided into phase groups according to requirements, and the number of phase groups is at least one.
[0060] S2. Cut the winding wire to a preset length and wind it around the stator teeth in the phase group to form a winding. The preset length of the winding wire is the total length of the winding wire required to wind all the stator teeth in the same phase group.
[0061] In other words, the preset length of the winding is cut off, and the total length of the winding required to complete the winding on all stator teeth in a phase group is the preset length of the winding.
[0062] Wires can be classified according to conductor material (copper, aluminum, alloy), insulation material (enameled wire, wrapped wire, inorganic insulated wire), and conductor shape (round wire, flat wire, etc.). This application does not limit the specific types of wires used in its embodiments.
[0063] S3. Based on the number of stator teeth in each winding, set the preset position of the winding and fix the preset position.
[0064] The requirements for the grouping and number of stator teeth vary depending on the type of motor. For example, Figure 3 As shown, the stator windings of brushless motors are mostly three-phase symmetrical windings, that is, there are six stator teeth 12, which are divided into three phase groups, with two stator teeth in each phase group.
[0065] In other words, based on the grouping and number of stator teeth 12, the preset position of the winding 20 is set, such as... Figure 3 As shown, there are six stator teeth 12, which are divided into three phase groups. Each phase group contains two stator teeth. The preset position of the winding 20 is the position between the two stator teeth in one phase group.
[0066] S4. Using a winding machine, the winding wire is simultaneously wound onto two stator teeth from both sides of a preset position to form a double-tail winding.
[0067] In other words, after fixing the preset position, two windings with fixed head wires are formed at the preset position. Starting from the head wires, the two windings simultaneously begin to wind around the stator teeth, eventually forming a double tail wire. The winding method provided by this application greatly reduces winding waste, avoids fixing the head wire at a position far away from the stator core, and avoids the waste caused by the remaining winding on the spool not being able to wind the entire stator.
[0068] In existing stator winding technology, the part wound first is called the head wire, and the part wound last is called the tail wire. In the same slot, the head wire wound first will be covered by the wire wound later, making it inconvenient to disassemble. When it is necessary to adjust the winding parameters, the entire winding must be removed and rewound, which is time-consuming and laborious.
[0069] The winding method provided in this application allows for adjustment of winding parameters simply by removing the wound portion of the wire, or even without removing the wound portion, thus ensuring winding efficiency.
[0070] In one embodiment, step S2 includes:
[0071] The preset winding length is calculated based on the relevant parameters of the double-tailed stator, which include the number of winding turns, core size, and winding tension.
[0072] In other words, the preset winding length is calculated based on factors such as the number of winding turns, core size, and winding tension to determine the required winding length to be cut. Additionally, relevant parameters for double-tailed stators include the winding length, double-tailed stator stack height, and number of double-tailed stator slots. This application does not limit the relevant parameters of the double-tailed stator; the preset winding length is calculated based on specific circumstances.
[0073] In one embodiment, step S3 includes:
[0074] Obtain two stator teeth within the phase group.
[0075] The length of the winding required to wind one of the two stator teeth is denoted as the first length.
[0076] The partial length of the required transition line between the two stator teeth is denoted as the second length.
[0077] The position reached after extending the first and second lengths from one end of the winding is the preset position of the winding.
[0078] In other words, first determine the winding length required to wind one stator tooth, then add the portion of the winding length required between two stator teeth to determine the preset winding position.
[0079] It should be understood that when the winding is wound around the stator teeth, the preset position of the winding is located at a certain position between the two stator teeth.
[0080] It should be noted that the length of the transition line matches the distance between the two stator teeth. When setting the preset position of the winding, a fixing point corresponding to the preset position between the stator teeth is also set to fix the preset position of the winding.
[0081] Preferably, the midpoint of the transition line between the two stator teeth is set as a preset position, that is, the preset position of the winding is fixed at the midpoint between the two stator teeth, so that the winding machine can synchronously wind the winding on both sides of the preset position, thereby further improving the winding efficiency.
[0082] As an example, such as Figure 3 As shown, there are six stator teeth 12, divided into three phase groups. Each phase group contains two stator teeth. The winding between the first stator tooth 121 and the second stator tooth 122 in the same phase group is a transition line 220. The middle position of the transition line 220 is set as a preset position. Figure 3 The first preset position 210 is the middle position between the first stator tooth 121 and the second stator tooth 122.
[0083] As another example, such as Figure 4 As shown, there are nine stator teeth 12, divided into three phase groups. The winding between the third stator tooth 123 and the fourth stator tooth 124 within the same phase group is a transition line, and the middle position of the transition line is a preset position. Figure 4 The second preset position 230 is the middle position between the third stator tooth 123 and the fourth stator tooth 124.
[0084] Preferably, in step S3, the two stator teeth that are furthest apart within the same phase group are obtained. Due to the limitation of the winding space, the two stator teeth that are furthest apart within the same phase group can ensure winding efficiency.
[0085] In one embodiment, step S3 includes:
[0086] The winding at a preset position is connected to the double-tailed stator using a fastener to fix the preset position of the winding.
[0087] In other words, a fixing device is used to fix the preset position of the winding at a fixed point between two stator teeth. The fixing device includes, but is not limited to, adhesives, locking components of mechanical mechanisms, and slots on the stator to engage the winding.
[0088] In one embodiment, step S4 includes:
[0089] When the number of stator teeth in the same phase group is greater than two, the winding machine is used to simultaneously wind the winding wires on both sides of the preset position onto the two stator teeth.
[0090] The remaining stator teeth in the same phase group are then wound using a winding machine to form a double-tailed winding.
[0091] In other words, when there are two stator teeth in the same phase group, for example: Figure 3 The stator structure shown has six stator teeth 12, divided into three groups, with two stator teeth in each group. A winding machine is then used to simultaneously wind the winding wire onto the two stator teeth from both sides of the first preset position, forming a double-tailed winding.
[0092] As an example, such as Figure 4 As shown, the winding machine is used to wind the wire onto the third stator tooth 123 and the fourth stator tooth 124. After the third stator tooth 123 and the fourth stator tooth 124 have completed winding, the winding machine is used to wind the fifth stator tooth 125, finally forming a double-tailed winding.
[0093] Furthermore, when the number of remaining stator teeth in the same phase group is even, the two stator teeth are wound simultaneously using a winding machine.
[0094] As an example, when there are two stator teeth remaining in the same phase group, the remaining two stator teeth are wound simultaneously using a winding machine. When there are four stator teeth remaining in the same phase group, the winding machine first winds two stator teeth simultaneously, and then winds the remaining two stator teeth.
[0095] When the number of remaining stator teeth in the same phase group is odd, the last stator tooth is wound separately using a winding machine.
[0096] As an example, when there is one stator tooth remaining unwound in the same phase group, the remaining stator tooth is wound using a winding machine. When there are three stator teeth remaining in the same phase group, the winding machine first winds two stator teeth, and then winds the last remaining stator tooth separately.
[0097] Because the winding is first cut off and its preset position is fixed, the winding forms a double-tail state. Then, the winding machine can be used to wind the two stator teeth in the same group, which not only saves winding material but also improves winding efficiency.
[0098] In a preferred embodiment, the number of stator teeth is six, and the stator teeth are divided into three groups. The midpoint of the winding is set as a preset position, and the position of the midpoint of the winding is fixed.
[0099] like Figure 3As shown, the first preset position 210 of the winding is fixed, and the winding machine is used to simultaneously wind the first stator tooth 121 and the second stator tooth 122 to form a double-tailed winding.
[0100] The winding method in this embodiment not only saves winding material, but also fixes the winding head between the first stator tooth 121 and the second stator tooth 122. When it is necessary to adjust the parameters of the first stator tooth 121 and the second stator tooth 122, the adjustment can be made directly without removing the winding and rewinding.
[0101] As an example, when increasing or decreasing the number of turns of the first stator tooth 121 and the second stator tooth 122, the increase or decrease can be made directly without disassembling and rewinding the winding.
[0102] In addition, such as Figure 4 As shown, Figure 4 The stator teeth 12 in the circuit are nine in number and divided into three phase groups. Each phase group has three stator teeth. When it is necessary to adjust the parameters of the third stator tooth 123, the fourth stator tooth 124 and the fifth stator tooth 125, only one stator tooth needs to be removed to adjust the parameters. Compared with removing all the windings, the winding efficiency is improved.
[0103] This application also provides a winding device for a double-tailed stator, such as... Figure 5 As shown, the double-tailed stator includes an iron core, the iron core includes a stator yoke and a plurality of stator teeth surrounding the stator yoke, and the winding device includes a grouping module, a cutting module, a fixing module and a winding module.
[0104] The grouping module is configured to group multiple stator teeth into at least one phase group.
[0105] The cutting module is configured to cut a winding of a preset length. The winding is wound around all the stator teeth in the phase group to form a winding. The preset length of the winding is the total length of the winding required to wind all the stator teeth in the same phase group.
[0106] The fixing module is configured to set a preset position of the winding wire according to the number of stator teeth in each winding, and to fix the preset position.
[0107] The winding module is configured to use a winding machine to simultaneously wind the winding wire onto the two stator teeth from both sides of the preset position, forming a double-tailed winding.
[0108] In one embodiment, the trimming module includes a calculation unit configured to calculate the preset length of the winding based on relevant parameters of the double-tailed stator, including the number of winding turns, core size, and winding tension.
[0109] In one embodiment, the fixing module includes a first acquisition unit, a second acquisition unit, a third acquisition unit, and a preset unit, wherein the first acquisition unit is configured to acquire two stator teeth within the phase group.
[0110] The second acquisition unit is configured to acquire the length of the winding required to wind one of the two stator teeth, denoted as the first length.
[0111] The third acquisition unit is configured to acquire a portion of the required transition line length between the two stator teeth, denoted as the second length.
[0112] The preset unit is configured to be the position reached after extending the first length and the second length from one end of the winding, which is the preset position of the winding.
[0113] In one embodiment, the third acquisition unit includes an acquisition subunit configured to acquire half the length of the required transition line between the two stator teeth, denoted as the second length.
[0114] Furthermore, the first acquisition unit includes an acquisition subunit, which is configured to acquire the two stator teeth that are furthest apart within the same group.
[0115] In one embodiment, the fixing module further includes a fixing subunit configured to connect the winding at the preset position to the double-tailed stator using a fixing member, so as to fix the preset position of the winding.
[0116] In one embodiment, the winding module includes a first winding subunit and a second winding subunit.

[0117] The second winding subunit is configured to use the winding machine to wind the remaining stator teeth in the same phase group to form a double-tailed winding.
[0118] In one embodiment, the winding module further includes a third winding sub-unit, which is configured to simultaneously wind two stator teeth using the winding machine when the number of remaining stator teeth in the same group is even; and to wind the last stator tooth separately using the winding machine when the number of remaining stator teeth in the same group is odd.
[0119] In one embodiment, such as Figure 6 and Figure 7As shown, the double-tail stator 100 also includes stator end plates, which include a first end plate 310 and a second end plate 320, which are respectively connected to the two ends of the iron core 10. Figure 6 Exploded view of a double-tail stator. Figure 7 This is a schematic diagram of the structure after the double-tail stator is assembled. Slots are provided on the first end plate 310 and the second end plate 320. The slots form fixing members and are used to limit the preset position of the winding to fix the winding.
[0120] Of course, the fastener can also take other structural forms, such as fixing the winding to a winding mold. This application does not limit the embodiments; the basic principle is to fix the winding.
