Description

Technical Field

[0001] The utility model relates to a mover device and a linear motor, belonging to the technical field of motors. Background Art

[0002] Linear motors generally include a mover device and a stator device, wherein the mover device is generally composed of an iron core and a winding. The iron core is mostly made of silicon steel sheets, while the winding is wound with wires and fixed on the iron core. Electrical isolation is required between the winding and the iron core to ensure that the current in the winding does not flow directly to the iron core or other metal parts, thereby preventing short circuits.

[0003] In the existing technology, insulating paper is usually added between the winding and the core to electrically isolate the winding from the core. However, the main components of insulating paper are cellulose and insulating oil. As time goes by and the influence of external factors, the insulating oil may be decomposed and the cellulose may be oxidized, which will cause the insulating paper to age or even fail. The performance of insulating paper will also be affected by environmental factors such as temperature, humidity, and light. Changes in these environmental factors may cause the performance of insulating paper to deteriorate, and regular inspection and replacement are required. In addition, the wear resistance of insulating paper is relatively poor, and it is easy to wear and crack. The softness of insulating paper is also relatively general, which is not suitable for use scenarios that require folding and bending.

[0004] In view of this, it is indeed necessary to propose improvements to the existing mover device and linear motor to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0027] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0028] The utility model provides a linear motor (not shown), which includes a stator device and a mover device 100. Figure 1-4 As shown, a movable device 100 of a preferred embodiment of the utility model is provided, wherein the movable device 100 includes a winding module 110 and a core module 150, wherein the core module 150 includes a plurality of core teeth 151 arranged at intervals, the winding module 110 includes a plurality of movable windings 120, the movable windings 120 are sleeved outside the core teeth 151, the movable windings 120 include a coil 130 and an insulating member 140, and along the length direction of the movable winding 120, the insulating member 140 is symmetrically arranged on the inner sides of both ends of the coil 130, and the core teeth 151 are at least partially inserted into the insulating member 140.

[0029] By providing the insulating member 140 on the inner side of both ends of the coil 130, direct contact between the coil 130 and the core teeth 151 is effectively prevented, thereby enhancing the electrical insulation performance, which reduces the risk of failure caused by electrical short circuit or leakage, and improves the safety and reliability of the entire mover device 100. At the same time, by providing the insulating member 140 on the inner side of both ends of the coil 130, it is possible to better adapt to coils 130 of different lengths and mover devices 100 of different specifications. In addition, the core teeth 151 are at least partially inserted into the insulating member 140, which further protects the coil 130 and prevents friction or collision between the coil 130 and the core teeth 151 due to vibration or other mechanical factors. This protection can extend the service life of the coil 130 and improve the durability of the entire mover device 100.

[0030] Furthermore, the insulating member 140 includes a receiving groove 141 , and the core tooth 151 is partially inserted into the receiving groove 141 to enhance the protection of the coil 130 , avoid direct friction between the coil 130 and the core tooth 151 , and thereby protect the service life of the coil 130 .

[0031] Furthermore, the insulating member 140 further includes a first end 142 and a second end 143 disposed at both ends of the receiving slot 141, the first end 142 being perpendicular to the receiving slot 141 and extending in a direction away from the receiving slot 141, and the second end 143 being perpendicular to the receiving slot 141 and extending in a direction away from the receiving slot 141, and along the height direction of the mover winding 120, the coil 130 abuts against the first end 142 and the second end 143 respectively. The existence of the first end 142 and the second end 143 effectively isolates the coil 130 in the mover winding 120 from the external environment or other potential conductive components, thereby significantly improving the insulation performance and reducing the risk of short circuit or electric shock; at the same time, by making the coil 130 abut against the first end 142 and the second end 143 respectively, the position of the coil 130 in the receiving slot 141 is fixed, which helps to reduce the movement or deformation of the coil 130 during operation, thereby maintaining its performance and stability.

[0032] Furthermore, the accommodating groove 141 includes a groove bottom 144 and groove walls 145 located on both sides of the groove bottom 144, the groove walls 145 are perpendicular to the groove bottom 144 and extend from the groove bottom 144 toward the core tooth 151, the accommodating groove 141 includes a first surface facing the core tooth 151 and a second surface 147 facing away from the core tooth 151, the first surface abuts against the core tooth 151, the second surface 147 abuts against the coil 130, and a winding portion 148 is provided at the intersection of the groove wall 145 and the groove bottom 144 on the second surface 147, the winding portion 148 includes a plurality of continuously arranged recessed positions 1481, and the wire in the coil 130 abuts against the recessed positions 1481. By setting the recessed position 1481 on the second surface 147, the wire in the coil 130 can be better embedded in the recessed position 1481, which makes it more convenient and quick to wind the coil 130 on the outside of the insulating member 140. At the same time, during the movement of the movable device 100, relative sliding between the coil 130 and the insulating member 140 can also be avoided.

[0033] Furthermore, along the length direction of the coil 130, the inner side of the coil 130 is covered with insulating paper 170. The insulating paper 170 can prevent the portion of the core teeth 151 not inserted into the insulating member 140 from directly contacting the coil 130, further enhancing the electrical insulation of the mover device 100.

[0034] Furthermore, a step portion 1451 is provided on one side of the slot wall 145 facing the core tooth 151, and the step portion 1451 extends from the first end portion 142 to the second end portion 143, and the insulating paper 170 abuts against the step portion 1451. By providing the step portion 1451, the insulating member 140 at both ends of the coil 130 can restrict the insulating paper 170 to a fixed position, and during the movement of the mover device 100, displacement of the insulating paper 170 can be avoided.

[0035] Further, such as Figures 3-4 As shown, in this embodiment, a groove 160 is provided on the second end 143, and the groove 160 is arranged opposite to the groove bottom 144. The groove 160 is configured to allow the wire of the coil 130 to pass through. In order to facilitate the wire of the coil 130 to pass through, the groove 160 is provided on the second end 143 of the insulating member 140, so that the wire of the coil 130 can be conveniently passed outward from the groove 160. In some other embodiments, the groove 160 can also be provided on the first end 142, and the utility model is not limited by comparison.

[0036] For further information, see Figure 4 As shown, the groove 160 is located at one end of the winding portion 148. In this way, after the wire in the coil 130 is wound around the insulating member 140, it can directly pass through the groove 160, which is more convenient.

[0037] Furthermore, in the present embodiment, the insulating member 140 is made of plastic, which has good insulation properties and is low in cost, thus effectively reducing costs. In other embodiments, the insulating member 140 may also be made of rubber or other insulating materials, which is not limited in the present invention.

[0038] Further, such as Figure 1 As shown, in this embodiment, the mover device 100 also includes a shell 180, which is sleeved on the outside of the winding module 110 and the core module 150 to protect the winding module 110 and the core module 150 and extend the service life of the mover device 100.

[0039] In summary, the mover device of the utility model, by providing insulating parts on the inner side of both ends of the coil, effectively prevents direct contact between the coil and the core teeth, thereby enhancing the electrical insulation performance, which reduces the risk of failure caused by electrical short circuit or leakage, and improves the safety and reliability of the entire mover device. At the same time, by providing insulating parts on the inner side of both ends of the coil, it can better adapt to coils of different lengths and mover devices of different specifications. In addition, the core teeth are at least partially inserted into the insulating parts, which further protects the coil and prevents friction or collision between the coil and the core teeth due to vibration or other mechanical factors. This protection can extend the service life of the coil and improve the durability of the entire mover device.

[0040] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
