According to the financial industry on December 12, 2024, information from the State Intellectual Property Office shows that KUKA Robot (Guangdong) Co., Ltd. and KUKA Robot Manufacturing (Shanghai) Co., Ltd. have obtained a patent called "motor, robot joint module and robot", with the authorization announcement number CN 222127817 U, and the application date is March 2024.
The patent abstract shows that the present application relates to the field of motor technology, in particular to a motor, a robot joint module and a robot. The motor comprises a housing, a first end cover, a motor stator, an output shaft, a motor rotor, a brake and a first bearing. The motor stator is provided with a hollow hole, the output shaft is arranged through the hollow hole and the first end cover, and the motor rotor is arranged in the hollow hole and the stop rotation is connected to the output shaft. The brake is arranged in the accommodating cavity, the brake comprises a brake stator and a brake rotor, the brake rotor is connected with the output shaft stop and is embedded in the hollow hole at least partially, the brake stator is positioned between the first end cover and the brake rotor, and the brake stator is embedded in the limiting groove and is fixedly connected with the first end cover; The brake stator is provided with a center hole, and the brake stator is sleeved outside the output shaft through the center hole. The first bearing is sleeved on the output shaft and at least partially accommodated in the center bore. The axial size of the above-mentioned motors is reduced, the overall weight is lower, and the power density is high.
