Description

Technical Field

[0001] The utility model relates to the technical field of equipment parts and components, in particular to a device for automatically feeding a brushless motor stator. Background Art

[0002] The stator of a brushless motor is an important part of a brushless motor. The stator is usually composed of an iron core and windings. The iron core is generally made of laminated silicon steel sheets, and its function is to enhance the conduction of the magnetic field and concentrate the magnetic lines of force. The windings are distributed on the iron core in a specific winding method. When current passes through the windings, a magnetic field is generated, which interacts with the rotor magnetic field to achieve the operation of the motor. The stator of a brushless motor plays a vital role in the operation of the brushless motor, and its performance is directly related to the performance of the entire motor.

[0003] However, in the existing production and processing of brushless motor stators, when assembling stator parts and transferring between processing steps, the stator body needs to be transported to a conveyor line for the next processing step. The stator transfer work is usually done manually by transportation workers. Due to the limited speed of manual operation, it cannot be compared with the fast and continuous operation of automated equipment, which can easily cause bottlenecks in the production process and reduce overall production efficiency.
