Description

Technical Field

[0001] This utility model relates to the field of motor rotor core technology, and in particular to a novel low-loss motor rotor core. Background Technology

[0002] The rotor core is a crucial component in an electric motor or generator, providing the magnetic circuit to generate a magnetic field. Rotor cores are typically made of silicon steel sheets or other magnetic materials and have specific shapes and structures to ensure efficient energy conversion and transmission. In an electric motor or generator, the primary function of the rotor core is to generate an induced electromotive force during rotation, thereby achieving energy conversion.

[0003] However, most existing low-loss motor rotor cores are composed of multiple iron sheets, which are then pressed together by a stacking machine. During the subsequent assembly process, collisions are inevitable, causing misalignment of the iron sheets.

[0004] Therefore, those skilled in the art have provided a novel low-loss motor rotor core to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a novel low-loss motor rotor core. This motor rotor core has a stable structure and avoids the problem of misalignment of iron pieces.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel low-loss motor rotor core includes a core body and a motor shaft. The core body is composed of multiple stacked iron sheets, each of which is provided with a connecting mechanism. A reinforcing mechanism is provided in the middle of the core body and outside the motor shaft.

[0008] The connecting mechanism includes three sets of adhesive components and positioning components. The three sets of adhesive components and positioning components are arranged in an array on the iron sheet. The adhesive component includes a storage film, which is adhered to the upper end of the iron sheet. Multiple glue storage beads are fixedly arranged inside the storage film. The positioning component includes a positioning block and a positioning groove. The positioning block is fixedly arranged on the upper end of the iron sheet, and a magnetic block is fixedly arranged on the upper end of the positioning block.

[0009] Furthermore, the reinforcing mechanism includes three insertion holes and a fixing ring. The three insertion holes are all opened on the iron sheet. The lower end of the fixing ring is fixedly connected with three rods at equal intervals. The three rods are respectively inserted into the corresponding insertion holes. The lower ends of the three rods all penetrate the iron core body and are fixedly connected with threaded sections.

[0010] The above technical solution not only further improves the connection strength between multiple iron plates by strengthening the mechanism, but also facilitates the installation of the iron core body on the motor shaft, bringing great convenience to the staff.

[0011] Furthermore, the reinforcing mechanism also includes a fastening nut, the fastening nut being threaded onto the outer wall of the threaded section;

[0012] The above technical solution allows the threaded section to fit onto the motor shaft by screwing in the fastening nut.

[0013] Furthermore, an adhesive piece is fixedly provided at the lower end of the storage film, and the storage film is adhered to the upper end of the iron sheet by the adhesive piece;

[0014] The above technical solution uses an adhesive patch to bond the storage film to the iron sheet.

[0015] Furthermore, the positioning groove is formed at the lower end of the iron sheet, the positioning block is engaged inside the positioning groove of the adjacent iron sheet, and the positioning block is magnetically connected to the iron sheet through a magnetic block;

[0016] The above technical solution enables rapid connection between two adjacent iron sheets.

[0017] Furthermore, each of the multiple iron sheets has a shaft hole in its middle, through which the motor shaft passes.

[0018] Furthermore, multiple heat dissipation holes are equally spaced on each of the aforementioned iron sheets;

[0019] The above technical solution improves the heat dissipation effect of the iron core body during operation by using heat dissipation holes.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model proposes a novel low-loss motor rotor core. The motor rotor core can quickly and accurately position and connect multiple iron pieces through a positioning component. Furthermore, through the action of the adhesive component, the connection strength of two adjacent iron pieces after stacking is improved, thereby improving the stability of the core and preventing the iron pieces from misaligning during use.

[0022] 2. This utility model proposes a novel low-loss motor rotor core. The motor rotor core, through a strengthening mechanism, not only further improves the connection strength between multiple iron plates, but also facilitates the installation of the core body on the motor shaft, bringing great convenience to the staff.

[0034] An adhesive piece 513 is fixedly provided at the lower end of the storage film 511. The storage film 511 is adhered to the upper end of the iron sheet 2 through the adhesive piece 513, and the storage film 511 is adhered to the iron sheet 2 through the adhesive piece 513.

[0035] The positioning groove 523 is opened at the lower end of the iron sheet 2, and the positioning block 521 is snapped into the positioning groove 523 of the adjacent iron sheet 2. The positioning block 521 is magnetically connected to the iron sheet 2 through the magnetic block 522, so that the two adjacent iron sheets 2 can be quickly connected.

[0036] Multiple iron plates 2 are provided with shaft holes 3 in the middle, and the motor shaft 4 passes through the shaft holes 3.
