Description

Technical Field

[0001] The utility model relates to the technical field of stator structures, in particular to a rotatable stator structure. Background Technique

[0002] With the increasing requirements for energy conservation and environmental protection, motors, as key power sources, must also meet the standards of high efficiency and low energy consumption. The advantages of brushless DC motors, such as low noise, long lifespan, no spark interference, and convenient centralized control, fully meet these requirements. With the increasing maturity of its speed regulation technology and the increasing cost performance, its structural manufacturing process must also be improved accordingly.

[0003] A brushless motor is a motor without carbon brushes and a commutator. It drives the rotor to rotate by controlling the current in the coil through an electronic controller. It uses a set of electronic devices to sense the position of the permanent magnet poles through Hall elements or coil back electromotive force. According to this sensing, an electronic circuit is used to timely switch the direction of the current in the coil to ensure the generation of the correct magnetic force to drive the motor. Due to the absence of carbon brush friction, brushless motors have a longer lifespan, higher efficiency, and lower noise.

[0004] The purpose of this structure is to design a stator structure that does not require special tooling and fixtures, and has self-positioning, self-limiting, and self-assembling into a complete circle, ensuring accuracy while reducing costs and increasing efficiency. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a rotatable stator structure that provides protection for the stator core body through a stator skeleton. Multiple groups of stator cores are connected through the connection structures on their own stator skeletons, enabling multiple groups of outer arc plates and inner arc plates to form an outer circle and an inner circle, facilitating installation and fixation. The connection structures facilitate rapid assembly and disassembly by operators, improving the practicality of the device.

[0006] A rotatable stator structure of the utility model includes a stator core, an inner arc plate, an outer arc plate, and a stator skeleton. A group of outer arc plates and a stator skeleton are respectively arranged at the front and rear parts of the stator core. The stator skeleton is arranged on the stator core through plastic coating processing. Connection structures are arranged on the stator skeleton. The completed stator structure is composed of 9 connected stator cores. The stator skeleton provides protection for the stator core body. Multiple groups of stator cores are connected through the connection structures on their own stator skeletons, enabling multiple groups of outer arc plates and inner arc plates to form an outer circle and an inner circle, facilitating installation and fixation. The connection structures facilitate rapid assembly and disassembly by operators, improving the practicality of the device.

[0007] Preferably, the connecting structure includes a bolt structure, an insertion groove, and a bolt. The bolt structure is installed on the upper right end face of the stator skeleton, the bolt is arranged on the upper left end face of the stator skeleton, and the insertion groove is arranged on the upper outer side of the bolt structure; the stator skeletons on two adjacent groups of stator cores can be connected through the bolt and the bolt structure, and the bolt can be inserted into the bolt structure through the insertion groove, so as to facilitate the rapid connection of multiple groups of stator cores, improving the installation and disassembly efficiency of the operator and the practicability of the device.

[0008] Preferably, it further includes a limiting groove. The limiting groove is arranged on the right end face of the bolt structure and communicates with the lower part of the insertion groove; by rotating the connected stator cores, the bolt rotates from the area where the insertion groove is located to the limiting groove on the bolt structure, thereby limiting and fixing the connection between the bolt and the bolt structure. The device completes self-limiting and self-positioning, facilitating rapid assembly by the installer and improving the practicability of the device.

[0009] Preferably, it further includes an arc groove. The arc grooves are arranged on the front end face and the rear end face of the stator skeleton, and the stator skeleton does not cover the outer side of the outer arc plate and the inner side of the inner arc plate; through the arc grooves arranged on the stator skeleton, the wear debris generated by the rotation of the rotor on the inner and outer side faces of the stator skeleton during actual operation is reduced, which may affect the normal operation of the device, improving the stability and practicability of the device.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: the stator skeleton provides protection for the main body of the stator core, and multiple groups of stator cores are connected through the connecting structures on their own stator skeletons, enabling multiple groups of outer arc plates and inner arc plates to form an outer circle and an inner circle, facilitating installation and fixation. The connecting structure facilitates rapid assembly and disassembly by the operator, improving the practicability of the device. Description of the Drawings
