How to choose the appropriate robot joint motor?

We have introduced the basic components of industrial robots - joints. In today's article, we will introduce the selection of joint motors for robots.

To design and select a suitable joint motor, multiple factors need to be considered.

Firstly, workload requirements are an important consideration in joint design. Select the appropriate type and size of joint motor based on the size and type of workload to ensure that the robot can withstand and operate the required weight and force.

Secondly, the range of motion and degree of freedom are key elements in joint design. Select the appropriate type and quantity of joint motors based on the required range of motion and flexibility of the robot to achieve the desired multi axis motion and attitude adjustment.

Then, accuracy and repeatability are also important considerations in joint design. Robots need to have high precision and repeatability when performing fine tasks, so the structure and control system of joint motors need to have corresponding performance.

In addition, the selection of drive and control systems also affects the performance and functionality of joints. Select appropriate joint motor types, reducers, sensors, and controllers according to specific requirements to achieve precise control and adjustment of joint motion.

Finally, joint safety considerations are also crucial. In industrial environments, robots must be able to safely interact with human operators and surrounding devices. Therefore, the design of joint motors should include safety mechanisms such as collision detection, torque limitation, and emergency stop functions to ensure the safety and reliability of robot operation.

In summary, joints, as the basic components of industrial robot structures, play an important role in connecting and driving. The design and working principles of rotary and translational joints are crucial for the performance and functionality of robots. By selecting appropriate joint motors, considering workload requirements, range of motion and degrees of freedom, accuracy and repeatability, drive and control systems, as well as safety considerations, efficient, precise, and safe industrial robot operations can be achieved. In the future, with the development of industrial robot technology, joint structures will continue to evolve and innovate to meet constantly changing manufacturing needs.
