Problems solved by technology

[0003] Traditional robots can clearly see the servo motors leaking out of their joints. In addition to the motors we can see, there are also very complicated reducers and brake mechanisms in these joints, making the joints of the robot become very bloated

Abstract

The invention discloses a robot joint rotating device directly driven by a frameless type permanent magnet synchronous motor. The robot joint rotating device comprises a front arm, a rotating shaft and a rear arm. A mounting hole is formed in the end of the front arm. The rotating shaft is installed in the mounting hole through a bearing. The rear arm is connected with the rotating shaft and rotates around the front arm through the rotating shaft. The robot joint rotating device directly driven by the frameless type permanent magnet synchronous motor is characterized in that the rotating shaftis directly driven by the frameless type permanent magnet synchronous motor. According to the robot joint rotating device directly driven by the frameless type permanent magnet synchronous motor, therobot joint rotating device is simple in structure, small in installation size and high in control precision.

Description

technical field [0001] The invention relates to the technical field of robot equipment, in particular to a robot joint rotation device directly driven by a frameless permanent magnet synchronous motor. Background technique [0002] With the development of modern technology, robots are playing an increasingly important role in all walks of life. As a relatively important part of robots, robot joint rotation devices have attracted more and more attention. [0003] Traditional robots can clearly see the servo motors leaking out of their joints. In addition to the motors we can see, there are also very complicated reducers and brake mechanisms in these joints, making the joints of the robot become extremely bloated. Of course for many large robots this is not a problem. But for those small robots that are being increasingly used in the market and around equipment, especially collaborative robots that need to cooperate with people to complete various complex auxiliary productio...
