AI Technical Summary
Technical Problem
The axial dimension of existing robot joint drive modules is too long, resulting in large space occupation and increased weight, which affects the compactness and lightweight design of the whole machine.
Method used
The rotor shaft is coaxially inserted into the through hole of the fixed base, and the reducer assembly is built into the mounting hole of the rotor shaft. Combined with high thermal conductivity materials and heat pipe heat dissipation system, the radial integration of motor and reducer is achieved, shortening the axial dimension and improving heat dissipation efficiency.
Benefits of technology
The joint drive module achieves a compact structure, high integration, and miniaturized design, while improving heat dissipation efficiency and reliability.

Abstract
This invention discloses a joint drive module suitable for robots, including a fixed base, a stator assembly, a rotor assembly, and a reducer assembly. The fixed base has a through hole. The rotor assembly includes a rotor shaft and a rotor magnet component. The rotor shaft is coaxially disposed in the through hole and rotatably supported and connected to the fixed base. The rotor shaft has a coaxially disposed mounting hole. The stator assembly includes a stator core disposed radially outside the fixed base and fixedly connected to it. The stator core and the rotor shaft are coaxially disposed. A coil winding is wound on the stator core. The rotor magnet component is located radially outside the stator core and coaxially disposed with the rotor shaft. The rotor magnet component is fixedly connected to the rotor shaft through a connecting bracket. The reducer assembly includes a reduction transmission component and a reducer mounting seat. The reduction transmission component is disposed in the mounting hole of the rotor shaft. The input end of the reduction transmission component is kinetically connected to the rotor shaft. The reducer mounting seat is fixedly connected to the fixed base.
