Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a winding method for a stator winding of a motor, and a motor and equipment using the winding method. Background Art

[0002] Currently, the stator windings of existing compressor direct-wound stators are mainly wound on the stator teeth of the stator core using a winding machine. Among them, the three-phase winding structure of the stator is divided into a U-phase winding structure, a V-phase winding structure, and a W-phase winding structure.

[0003] Traditionally, winding the three-phase windings of a stator is primarily performed using the three nozzles of a winding machine. The three nozzles are positioned at adjacent angles and spaced at equal intervals. After the three nozzles simultaneously wind the first set of adjacent three-phase windings, they rotate the nozzles to wind the next set of three-phase windings. Therefore, each time a set of three-phase windings is wound, the stator core is subjected to the tension of the winding wire in a small area adjacent to the three nozzles. The greater the number of slots in the stator, the smaller the angles between the three nozzles. Consequently, the remaining angular area around the stator core is not subject to the tension of the winding wire, resulting in uneven stress on the stator core at the same time. This can easily lead to deformation of the stator core, which can cause problems such as reduced motor efficiency and increased noise. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to overcome the shortcomings of the existing technology and provide a winding method for the stator winding of a motor, which can balance the forces on the stator core and the winding nozzle during the winding process, greatly reducing the deformation of the stator core, and effectively improving the winding accuracy, so that the coils are arranged neatly, thereby improving the efficiency of the motor and improving the noise problem.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A method for winding a stator winding of a motor, wherein the stator winding is wound around stator teeth of a stator core, winding slots are formed between adjacent stator teeth, and a resin skeleton is connected to the upper and lower ends of the stator core, respectively. The number of rotor poles of the motor is P, where P = 4, 8, or 10; the number of winding slots is Q, where Q = 3*P / 2; the stator winding includes a U-phase winding, a V-phase winding, and a W-phase winding, wherein the winding of each phase is composed of P / 2 coils connected in series, and the angle between two adjacent coils of the same phase winding is β, where β = 2*360° / P.

[0007] The winding method of the stator winding of the motor comprises the following steps:

[0008] S1, place three winding nozzles in three winding slots of the stator core at an angle of 120°;

[0009] S2, winding the stator teeth adjacent to each other and on the same side through three winding nozzles to form the first set of coils of the U-phase winding, the V-phase winding and the W-phase winding respectively;

[0012] As an implementation manner, the winding method in steps S1 to S4 adopts a delta connection method or a star connection method.

[0013] Therefore, the embodiment of the present invention performs the stator winding operation by distributing the three winding nozzles at 120° intervals. During the winding process, the force on the stator core is balanced, which greatly reduces the deformation of the stator core, thereby improving the efficiency of the motor and improving the noise problem. Furthermore, during the winding process, the force on the three winding nozzles is also balanced, which effectively improves the winding accuracy, arranges the coils neatly, and avoids the winding circumference from becoming longer, thereby improving the efficiency of the motor.

[0049] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the present disclosure and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of the present invention.

[0050] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "left", "right", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0051] Traditionally, winding the three-phase windings of a stator is primarily performed using the three nozzles of a winding machine. The three nozzles are positioned at adjacent angles and spaced at equal intervals. After the three nozzles simultaneously wind the first set of adjacent three-phase windings, they rotate the nozzles to wind the next set of three-phase windings. Therefore, each time a set of three-phase windings is wound, the stator core is subjected to the tension of the winding wire in a small area adjacent to the three nozzles. The greater the number of slots in the stator, the smaller the angles between the three nozzles. Consequently, the remaining angular area around the stator core is not subject to the tension of the winding wire, resulting in uneven stress on the stator core at the same time. This can easily lead to deformation of the stator core, which can cause problems such as reduced motor efficiency and increased noise.

[0052] In view of this, the present invention provides a winding method for the stator winding of a motor, which can balance the forces on the stator core 11 and the winding nozzle during the winding process, greatly reducing the deformation of the stator core 11, and effectively improving the winding accuracy, so that the coils are arranged neatly, thereby improving the efficiency of the motor and improving the noise problem.

[0053] See also Figures 1 to 7 This embodiment provides a winding method for a stator winding of a motor, wherein the stator winding is wound around the stator teeth 12 of the stator core 11, and winding slots 13 are formed between adjacent stator teeth 12. The upper and lower ends of the stator core 11 are respectively connected to resin frames; the number of rotor poles of the motor is P, where P=4, 8, or 10; the number of winding slots 13 is Q, where Q=3*P / 2; the stator winding includes a U-phase winding, a V-phase winding, and a W-phase winding, and the winding of each phase is composed of P / 2 coils connected in series, and the angle between two adjacent coils of the same phase winding is β, where β=2*360° / P; The method for winding the stator winding of the motor includes the following steps: S1, placing three winding nozzles at an angle of 120° in three winding slots 13 of the stator core 11; S2, winding the stator teeth 12 adjacent to each other and on the same side through the three winding nozzles to form the first set of coils of the U-phase winding, the V-phase winding and the W-phase winding respectively; S3, rotating the three winding nozzles at an angle β at the same time, and during the rotation process, the wires on the three winding nozzles respectively form a transition line fixed on the resin frame; S4, repeating steps S2 and S3 in sequence until the last set of coils of the U-phase winding, the V-phase winding and the W-phase winding are wound.

[0054] The winding method in steps S1 to S4 adopts a delta connection method or a star connection method.

[0055] Therefore, the embodiment of the present invention performs the stator winding operation by distributing the three winding nozzles at 120° intervals. During the winding process, the force on the stator core 11 is balanced, which greatly reduces the deformation of the stator core 11, thereby improving the efficiency of the motor and improving the noise problem; furthermore, during the winding process, the force on the three winding nozzles is also balanced, which effectively improves the winding accuracy, arranges the coils neatly, and avoids the winding circumference from becoming longer, thereby improving the efficiency of the motor.

[0056] In some optional embodiments, see Figure 1 When the number of rotor poles P of the motor of this embodiment is 8, the number Q of the winding slots 13 is 12, the U-phase winding, the V-phase winding, and the W-phase winding are each composed of four groups of coils connected in series, and the angle β between two adjacent coils of the same phase winding is 90°; the winding method of the stator winding of the motor includes the following steps:

[0057] S1, placing three winding nozzles in three winding slots 13 of the stator core 11 at an angle of 120°;

[0058] S2, winding the stator teeth 12 adjacent to each other and on the same side through three winding nozzles to form the U1 coil, V2 coil, and W3 coil of the U-phase winding, V-phase winding, and W-phase winding respectively;

[0059] S3: After the winding of the first set of coils is completed, the three winding nozzles are rotated simultaneously by 90 degrees so that the three winding nozzles reach the next set of winding stations; during the rotation process, the wires on the three winding nozzles respectively form a transition line fixed on the resin frame;

[0060] S4, repeating steps S2 and S3 in sequence to form the U2 coil, V3 coil, and W4 coil of the U-phase winding, the V-phase winding, and the W-phase winding respectively;

[0062] S6, repeat step S2 to form the U4 coil, V1 coil, and W2 coil of the U-phase winding, V-phase winding, and W-phase winding respectively; at this point, the winding operation of the U-phase winding, V-phase winding, and W-phase winding of the stator is completed.

[0063] In step S6, the U-phase winding is composed of U1, U2, U3, and U4 coils connected in series, the V-phase winding is composed of V1, V2, V3, and V4 coils connected in series, and the W-phase winding is composed of W1, W2, W3, and W4 coils connected in series; and the U1 coil, V1 coil, W1 coil, U2 coil, V2 coil, W2 coil, U3 coil, V3 coil, W3 coil, U4 coil, V4 coil, and W4 coil are arranged circumferentially in sequence.

[0064] like Figure 2 and Figure 3 As shown, in this embodiment, a delta connection is used for winding. Specifically, the incoming wire of the U1 coil is connected to the outgoing wire of the W2 coil and serves as the lead wire of the U-phase winding. The incoming wire of the V2 coil is connected to the outgoing wire of the U4 coil and serves as the lead wire of the V-phase winding. The incoming wire of the W3 coil is connected to the outgoing wire of the V1 coil and serves as the lead wire of the W-phase winding. The delta connection has no neutral point.

[0065] like Figure 4 and Figure 5 As shown, in this embodiment, the winding method adopts a star connection. Specifically, the incoming wires of the U1 coil, V2 coil, and W3 coil serve as the outgoing wires of the U-phase winding, V-phase winding, and W-phase winding, respectively, and are used to connect to the external power drive structure. The outgoing wires of the U4 coil, V1 coil, and W2 coil are connected together to form the neutral point of the stator winding.

[0066] Therefore, the embodiment of the present invention performs the stator winding operation by distributing the three winding nozzles at 120° intervals. During the winding process, the force on the stator core 11 is balanced, which greatly reduces the deformation of the stator core 11, thereby improving the efficiency of the motor and improving the noise problem; furthermore, during the winding process, the force on the three winding nozzles is also balanced, which effectively improves the winding accuracy, arranges the coils neatly, and avoids the winding circumference from becoming longer, thereby improving the efficiency of the motor.
