Description

Technical Field

[0001] This application relates to the field of electrical machinery technology, and in particular to an armature. Background Technology

[0002] In existing technologies, armature windings aim to reduce the overlap of rotor windings on the rotor, resulting in high efficiency and low cost. However, in this approach, if the winding in one slot fails, the entire rotor will fail. Furthermore, for rotors with common six-slot armature windings, their rotational smoothness and stability are relatively poor, further increasing the probability of slot winding failure. Therefore, there is room for further improvement. Utility Model Content

[0003] This application proposes an armature that aims to improve the stability of motor operation, increase the fault tolerance of the motor, and reduce the risk caused by motor failure.

[0004] Specifically, the armature is wound using enameled wire, a method suitable for permanent magnet DC brushed motors. By employing 10 armature windings with 4 poles and 10 slots, the rotor rotation is smoother, thus improving the motor's operational stability. Furthermore, this redundant winding method allows the motor to continue operating even if a slot fails, thereby increasing the motor's fault tolerance and reducing the risk of motor failure.

[0005] The armature provided in this application adopts the following technical solution:

[0006] An armature includes a rotor and rotor windings. The rotor has a first pole, a second pole, a third pole, a fourth pole, a fifth pole, a sixth pole, a seventh pole, an eighth pole, a ninth pole, and a tenth pole arranged sequentially in a clockwise direction with a rotation axis as the center. Slots for accommodating the rotor windings are formed between adjacent poles. The rotor windings are constructed by sequentially winding a first winding, a second winding, a third winding, a fourth winding, a fifth winding, a sixth winding, a seventh winding, an eighth winding, a ninth winding, and a tenth winding from a single wire.

[0007] The first winding is wound on the fifth and sixth poles; the second winding is wound on the fourth and fifth poles; the third winding is wound on the third and fourth poles; the fourth winding is wound on the second and third poles; the fifth winding is wound on the first and second poles; the sixth winding is wound on the tenth and first poles; the seventh winding is wound on the ninth and tenth poles; the eighth winding is wound on the eighth and ninth poles; the ninth winding is wound on the seventh and eighth poles; and the tenth winding is wound on the sixth and seventh poles.

[0008] By adopting the above technical solution, the armature of this utility model has the following advantages compared with the prior art: First, by using 10 armature windings with 4 poles and 10 slots, the rotation of the motor rotor can be made smoother, thereby improving the stability of motor operation; Second, by winding the first winding, second winding, third winding, fourth winding, fifth winding, sixth winding, seventh winding, eighth winding, ninth winding, and tenth winding onto the fifth and sixth poles, the fourth and fifth poles, the third and fourth poles, the second and third poles, the first and second poles, the tenth and first poles, the ninth and tenth poles, the eighth and ninth poles, the seventh and eighth poles, and the sixth and seventh poles respectively, the armature windings are not only wound adjacent to each other on the poles of the rotor, but also stacked on top of each other, making the armature windings more redundant and mutually backup. Even if a slot winding fails, the redundant armature windings will automatically take over and continue to work, thereby maintaining the normal operation of the motor, thus improving the fault tolerance of the motor and reducing the risk caused by motor failure.

[0009] Preferably, the system further includes a commutator comprising a first commutator segment, a second commutator segment, a third commutator segment, a fourth commutator segment, a fifth commutator segment, a sixth commutator segment, a seventh commutator segment, an eighth commutator segment, a ninth commutator segment, and a tenth commutator segment. Each of the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, and tenth commutator segments is provided with a hook. A first winding is wound with the wires starting from the hook on the third commutator segment. The wires connecting the first winding to the second winding are sequentially hooked onto the hooks on the seventh and second commutator segments. The wires connecting the second and third windings are sequentially hooked onto the hooks on the sixth and first commutator segments. The wires connecting the third and fourth windings are sequentially hooked onto the hooks on the fifth and tenth commutator segments. The hooks of the commutator segments and the hook of the tenth commutator segment; the wires connecting the fourth winding to the fifth winding are sequentially hung on the hooks of the fourth commutator segment and the hooks of the ninth commutator segment; the wires connecting the fifth winding to the sixth winding are sequentially hung on the hooks of the third commutator segment and the hooks of the eighth commutator segment; the wires connecting the sixth winding to the seventh winding are sequentially hung on the hooks of the second commutator segment and the hooks of the seventh commutator segment; the wires connecting the seventh winding to the eighth winding are sequentially hung on the hooks of the first commutator segment and the hooks of the sixth commutator segment; the wires connecting the eighth winding to the ninth winding are sequentially hung on the hooks of the tenth commutator segment and the hooks of the fifth commutator segment; the wires connecting the ninth winding to the tenth winding are sequentially hung on the hooks of the ninth commutator segment and the hooks of the fourth commutator segment; the tenth winding, which is hung on the hook of the eighth commutator segment, is the end of the wires.

[0010] By adopting the above technical solution, firstly, the wire starts from the hook of one commutator segment and is wound around two adjacent poles. Secondly, the wire hooks onto the hook of another commutator segment, and the position of this commutator segment is almost symmetrical to that of the starting commutator segment. Then, the wire hooks onto the hook of the commutator segment adjacent to the starting commutator segment in a clockwise direction. Finally, the wire winds from this commutator segment onto one pole of the previous winding and its adjacent pole in a clockwise direction, and so on in a cyclical manner. By using one commutator segment as a transition, although the wire uses adjacent windings, the connection between the wire and the commutator segment hook adopts a balanced connection plan, which helps to ensure the overall uniformity of the armature winding process.

[0011] Preferably, the first commutator segment is positioned near the sixth and seventh poles; the second commutator segment is positioned near the seventh and eighth poles; the third commutator segment is positioned near the eighth and ninth poles; the fourth commutator segment is positioned near the ninth and tenth poles; the fifth commutator segment is positioned near the tenth pole and the first pole; the sixth commutator segment is positioned near the first and second poles; the seventh commutator segment is positioned near the second and third poles; the eighth commutator segment is positioned near the third and fourth poles; the ninth commutator segment is positioned near the fourth and fifth poles; and the tenth commutator segment is positioned near the fifth and sixth poles.

[0012] By adopting the above technical solution, the two hooks almost symmetrically divide the rotor's cross-section, and the winding is located between two adjacent hooks. This ensures that the armature is not at the same point when it is hooked, wound, or hooked again. As a result, the force on the armature is evenly distributed during the winding process, and the forces at the previous point are mutually neutralized and balanced. This makes the force on the entire armature more dispersed during the winding process, which is beneficial to ensuring the stability of the armature during the winding process.

[0013] Preferably, the first winding and the sixth winding are symmetrically arranged about the rotor's rotation axis, the second winding and the seventh winding are symmetrically arranged about the rotor's rotation axis, the third winding and the eighth winding are symmetrically arranged about the rotor's rotation axis, the fourth winding and the ninth winding are symmetrically arranged about the rotor's rotation axis, and the fifth winding and the tenth winding are symmetrically arranged about the rotor's rotation axis.

[0014] By adopting the above technical solution, the windings are evenly arranged on the rotor.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. First, by using 10 armature windings with 4 poles and 10 slots, the rotation of the motor rotor is made smoother, thereby improving the stability of motor operation. Second, by winding the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, and tenth windings sequentially onto poles 5 and 6, 4 and 5, 3 and 4, 2 and 3, 1 and 2, 10 and 1, 9 and 10, 8 and 9, 7 and 8, and 6 and 7 respectively, the armature windings are not only wound adjacent to each other on the rotor poles, but also stacked on top of each other, making the armature windings more redundant and providing backup for each other. Even if a slot winding fails, the redundant armature windings will automatically take over, thus maintaining the normal operation of the motor, thereby improving the motor's fault tolerance and reducing the risk of motor failure.

[0017] 2. First, the wire starts from the hook of one commutator segment and is wound around two adjacent poles. Next, the wire hooks onto the hook of another commutator segment, the position of which is nearly symmetrical to the starting commutator segment. Then, the wire hooks onto the hook of the commutator segment adjacent to the starting commutator segment in a clockwise direction. Finally, the wire winds from this commutator segment onto one pole of the previous winding and its adjacent pole in a clockwise direction, repeating this cycle. By using a commutator segment as a transition, although the wire uses adjacent windings, the connection between the wire and the commutator segment hook adopts a balanced connection plan, which helps to ensure the overall uniformity of the armature winding process.

[0018] 3. The two hooks are almost symmetrically divided into the rotor cross-sections, and the winding is located between two adjacent hooks. This means that the armature is not at the same point when it is hooked, the winding is connected, or the next hook is connected. This makes the force on the armature evenly distributed during the winding process, and the forces at the previous point are mutually canceled and balanced. This makes the force on the entire armature more dispersed during the winding process, which helps to ensure the stability of the armature during the winding process. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1 and Figure 2 This application will be described in further detail.

[0023] This application discloses an armature.

[0024] Reference Figure 1 The device includes an armature comprising a rotor 1 and a rotor winding 2. The rotor 1 has a first pole 1.1, a second pole 1.2, a third pole 1.3, a fourth pole 1.4, a fifth pole 1.5, a sixth pole 1.6, a seventh pole 1.7, an eighth pole 1.8, a ninth pole 1.9, and a tenth pole 1.10 arranged sequentially in a clockwise direction with the rotation axis as the center. Slots for accommodating the rotor winding 2 are formed between adjacent poles. The rotor winding 2 is composed of a single wire wound sequentially into a first winding 2.1, a second winding 2.2, a third winding 2.3, a fourth winding 2.4, a fifth winding 2.5, a sixth winding 2.6, a seventh winding 2.7, an eighth winding 2.8, a ninth winding 2.9, and a tenth winding 2.10.

[0025] The first winding 2.1 is wound on the fifth pole 1.5 and the sixth pole 1.6; the second winding 2.2 is wound on the fourth pole 1.4 and the fifth pole 1.5; the third winding 2.3 is wound on the third pole 1.3 and the fourth pole 1.4; the fourth winding 2.4 is wound on the second pole 1.2 and the third pole 1.3; the fifth winding 2.5 is wound on the first pole 1.1 and the second pole 1.2; the sixth winding 2.6 is wound on the tenth pole 1.10 and the first pole 1.1; the seventh winding 2.7 is wound on the ninth pole 1.9 and the tenth pole 1.10; the eighth winding 2.8 is wound on the eighth pole 1.8 and the ninth pole 1.9; the ninth winding 2.9 is wound on the seventh pole 1.7 and the eighth pole 1.8; and the tenth winding 2.10 is wound on the sixth pole 1.6 and the seventh pole 1.7.

[0026] By employing 10 armature windings with 4 poles and 10 slots, the rotation of the motor rotor 1 is made smoother than in existing technologies, thereby improving the stability of motor operation. Secondly, by sequentially winding the first winding 2.1, the second winding 2.2, the third winding 2.3, the fourth winding 2.4, the fifth winding 2.5, the sixth winding 2.6, the seventh winding 2.7, the eighth winding 2.8, the ninth winding 2.9, and the tenth winding 2.10 onto poles 5.5 and 6.6, 4.4 and 5.5, 3.3 and 4.4, 2.2 and 3.3, and 10.10 respectively, the first winding is wound onto poles 1.5 and 1.6, 1.4 and 1.5, 1.3 and 1.4, 1.2 and 1.3, and 1.10 respectively. The armature windings on poles 1.1 and 1.2, pole 1.10 and pole 1.1, pole 1.9 and pole 1.10, pole 1.8 and pole 1.9, pole 1.7 and pole 1.8, pole 1.6 and pole 1.7 of rotor 1 are arranged so that the armature windings are not only wound sequentially adjacent to each other on the poles of rotor 1, but also stacked sequentially on each other. This makes the armature windings more redundant and provides backup for each other. Even if a winding in a slot fails, the redundant armature windings will automatically take over and continue to work, thus maintaining the normal operation of the motor. This improves the fault tolerance of the motor and reduces the risk caused by motor failure.

[0027] refer to Figure 1 and Figure 2 It also includes a commutator 3, which includes a first commutator segment 3.1, a second commutator segment 3.2, a third commutator segment 3.3, a fourth commutator segment 3.4, a fifth commutator segment 3.5, a sixth commutator segment 3.6, a seventh commutator segment 3.7, an eighth commutator segment 3.8, a ninth commutator segment 3.9, and a tenth commutator segment. Each of the first commutator segment 3.1, the second commutator segment 3.2, the third commutator segment 3.3, the fourth commutator segment 3.4, the fifth commutator segment 3.5, the sixth commutator segment 3.6, the seventh commutator segment 3.7, the eighth commutator segment 3.8, the ninth commutator segment 3.9, and the tenth commutator segment is provided with a hook.

[0028] The first winding 2.1 is wound with the hook attached to the third commutator segment 3.3 as the starting point;

[0029] The wires connecting the first winding 2.1 to the second winding 2.2 are sequentially hung on the hooks of the seventh commutator segment 3.7 and the hooks of the second commutator segment 3.2;

[0030] The wires connecting the second winding 2.2 to the third winding 2.3 are sequentially hung on the hooks of the sixth commutator segment 3.6 and the hooks of the first commutator segment 3.1;

[0031] The wires connecting the third winding 2.3 to the fourth winding 2.4 are sequentially hung on the hooks of the fifth commutator segment 3.5 and the tenth commutator segment;

[0032] The wires connecting the fourth winding 2.4 to the fifth winding 2.5 are sequentially hung on the hooks of the fourth commutator segment 3.4 and the hooks of the ninth commutator segment 3.9;

[0033] The wires connecting the fifth winding 2.5 to the sixth winding 2.6 are sequentially hung on the hooks of the third commutator segment 3.3 and the eighth commutator segment 3.8;

[0034] The wires connecting the sixth winding 2.6 to the seventh winding 2.7 are sequentially hung on the hooks of the second commutator segment 3.2 and the hooks of the seventh commutator segment 3.7;

[0035] The wires connecting the seventh winding 2.7 to the eighth winding 2.8 are sequentially hung on the hooks of the first commutator segment 3.1 and the sixth commutator segment 3.6;

[0036] The wires connecting the eighth winding 2.8 to the ninth winding 2.9 are sequentially hung on the hooks of the tenth commutator segment and the fifth commutator segment 3.5;

[0037] The wires connecting the ninth winding 2.9 to the tenth winding 2.10 are sequentially hung on the hooks of the ninth commutator segment 3.9 and the hooks of the fourth commutator segment 3.4;

[0038] The wire ends at the tenth winding 2.10, which is hooked on the eighth commutator segment 3.8.

[0039] This process involves starting with a hook on one commutator segment and winding it around two adjacent poles. Next, the wire hooks onto another commutator segment hook, with the second segment positioned almost symmetrically to the starting segment. Then, the wire hooks onto the hook of the commutator segment adjacent to the starting segment in a clockwise direction. Finally, it winds from a third commutator segment onto one pole of the previous winding and its adjacent pole in a clockwise direction, repeating this cycle. By using the first and third commutator segments as winding preparations and the second commutator segment as a transition, the wire, although using adjacent windings, employs a balanced hooking plan, which helps ensure the overall uniformity of the armature winding process.

[0040] Furthermore, in this embodiment, the first commutator segment 3.1 is positioned near the sixth pole 1.6 and the seventh pole 1.7; the second commutator segment 3.2 is positioned near the seventh pole 1.7 and the eighth pole 1.8; the third commutator segment 3.3 is positioned near the eighth pole 1.8 and the ninth pole 1.9; the fourth commutator segment 3.4 is positioned near the ninth pole 1.9 and the tenth pole 1.10; the fifth commutator segment 3.5 is positioned near the tenth pole 1.10 and the first pole 1.1; the sixth commutator segment 3.6 is positioned near the first pole 1.1 and the second pole 1.2; the seventh commutator segment 3.7 is positioned near the second pole 1.2 and the third pole 1.3; the eighth commutator segment 3.8 is positioned near the third pole 1.3 and the fourth pole 1.4; the ninth commutator segment 3.9 is positioned near the fourth pole 1.4 and the fifth pole 1.5; and the tenth commutator segment is positioned near the fifth pole 1.5 and the sixth pole 1.6.

[0041] This arrangement ensures that the two hooks on the wire are nearly symmetrical and evenly divide the cross-section of rotor 1. The winding is located between the two adjacent hooks, so that the armature is not at the same point when it is connected, the winding is connected, or the next connection is connected. This allows the force on the armature to be evenly distributed during the winding process, which cancels out and balances the force at the previous point. This makes the force on the entire armature more dispersed during the winding process, which helps to ensure the stability of the armature during the winding process.

[0042] Furthermore, in this embodiment, the first winding 2.1 and the sixth winding 2.6 are arranged symmetrically about the rotation axis of the rotor 1, the second winding 2.2 and the seventh winding 2.7 are arranged symmetrically about the rotation axis of the rotor 1, the third winding 2.3 and the eighth winding 2.8 are arranged symmetrically about the rotation axis of the rotor 1, the fourth winding 2.4 and the ninth winding 2.9 are arranged symmetrically about the rotation axis of the rotor 1, and the fifth winding 2.5 and the tenth winding 2.10 are arranged symmetrically about the rotation axis of the rotor 1. The windings are evenly arranged on the rotor 1.

[0043] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
