Abstract
The present invention discloses a planar articulated robot and an inner rotor joint device, including a base, a first inner rotor joint device provided on the base, a first mechanical arm driven by the first inner rotor joint device, and a manipulator connected to the first mechanical arm, wherein the first inner rotor joint device comprises a rotating shaft fixedly connected to the first mechanical arm and extending along a longitudinal axis, a low-speed rotor assembly located on an outer periphery of the rotating shaft, a high-speed rotor assembly located on an outer periphery of the low-speed rotor assembly, a magnetizing ring located between the low-speed rotor assembly and the high-speed rotor assembly in a circumferential direction, a stator core located on an outer periphery of the high-speed rotor assembly with a certain gap therebetween in the circumferential direction, and a casing covering an outer periphery of the stator core and fixedly connected to the stator core, and a coil is wound around the stator core. The present invention enables high transmission precision, high utilization rate of permanent magnets, simple and compact structure, and low cost.
