The invention relates to the technical field of motors, and discloses a yoke-free stator tooth, a stator core, a motor and a manufacturing method of the yoke-free stator tooth, the yoke-free stator tooth has a radial direction and an axial direction, and the yoke-free stator tooth comprises a stator tooth core; the two stator tooth shoe sets are arranged at intervals in the axial direction, and each stator tooth shoe set comprises two stator tooth shoes connected to the two sides of the stator tooth center respectively; the stator tooth core comprises a plurality of first tooth sheets with the same size, and the plurality of first tooth sheets are sequentially laminated along the radial direction. According to the yoke-free stator tooth, the stator tooth core is formed by radially laminating the plurality of first tooth sheets with the same size, that is, the sizes and the shapes of all the first tooth sheets are the same, so that the production efficiency is improved, the material waste is reduced, and the material cost is reduced. Standardized raw material plates can be used for the first tooth pieces of the same size, and the material utilization rate is further increased.

This utility model relates to the field of mold technology, specifically an internal pressure side-push forming mechanism. The internal pressure side-push forming mechanism is characterized by: a lower pad plate connected to the bottom of the lower mold base, a lower clamping plate connected to the top of the lower mold base, a lower ejector plate above the lower clamping plate, lower mold bending blocks on the left and right sides of the lower ejector plate, and pull-back blocks on the outer sides of the lower mold bending blocks on both sides, respectively connected to the lower mold bending blocks via pull-back screws and springs; a lower mold driving block is located between the lower mold bending blocks and the pull-back blocks, with the other end of the lower mold driving block passing through the lower ejector plate and the lower clamping plate and connecting to the lower mold base; the bottom of the lower ejector plate abuts against one end of a tension / compression spring, and the other end of the tension / compression spring passes through the lower clamping plate and is located inside the lower mold base. Compared with the prior art, by cooperating with the upper mold bending block, the internal pressure side-push forming lower mold bending block achieves the effect of bending on both sides, reducing rework issues.

The invention relates to the field of tactile feedback devices, and discloses a Z-direction broadband vibration device which comprises a vibrator part and a stator part, the vibrator part is composed of a parallel elastic piece, a convex-concave metal plate, a mass block, a permanent magnet and an upper metal plate, and the stator part is composed of a lower shell, an iron core, a coil and an F-PCB; the flat elastic sheet adopts a rectangular annular structure, so that the welding area is increased, the process is simplified, and the connection strength and reliability are improved; bulges are arranged at four corners of the convex-concave metal plate, so that the mass block is prevented from being in direct contact with the elastic sheet during falling, and the elastic sheet is prevented from deforming The integrated design of the iron core and the metal plate simplifies the assembly process, improves the impact resistance and the vibration performance, reduces the manufacturing cost, and prolongs the service life of the product. By optimizing the structural design and simplifying the production process, the stability, impact resistance and production efficiency of the vibration device are improved, the manufacturing cost is reduced, and the service life of the product is prolonged.
