AI Technical Summary
The existing split design of geared motors results in redundant and complex structures, large size, inability to adapt to small equipment, and complicated assembly process, making installation inconvenient.
The design adopts a planetary gear reducer motor, with the main housing, rotor assembly, stator assembly and internal gear ring arranged sequentially from the outside to the inside. The speed reduction is achieved through a two-stage planetary gear assembly, and the output shaft is directly connected to external equipment, which simplifies the structure, reduces the size and improves convenience.
It achieves a compact structure, high torque, and convenient installation, improving transmission efficiency and ease of use, and is suitable for the compact internal space of small equipment.
