Answer: The reason why robots use servo motors is high-precision motion control, force control, high stability and reliability, adaptability and flexibility, and improved overall performance.
Answer analysis:
The main reasons why robots use servo motors are as follows:
High-precision motion control
1. Position control: The servo motor can accurately control the position of the robot to ensure that the robot can accurately perform various tasks. This is especially important for application scenarios that require high-precision positioning, such as assembly, welding, etc.
2. Speed control: The servo motor can accurately control the rotation speed to meet the robot's different speed requirements. This is critical for application scenarios that require fast response or precise speed control.
Force control
Servo motors can also be used to control the force of the robot to ensure that the robot can avoid danger or damage when collaborating with humans or other robots. Through the feedback control system, the servo motor can adjust the output force or torque in real time to meet specific force control requirements.
High stability and reliability
1. Closed-loop control: The servo motor system usually adopts closed-loop control, which can continuously monitor the actual position and speed of the motor, and compare and adjust with the target value to ensure the stability and reliability of the system.
2. Fault protection: Servo motor systems are usually equipped with various protection and fault diagnosis functions, which can promptly issue alarms and take corresponding protective measures when the motor fails to prevent the fault from expanding or causing more serious consequences.
Adaptability and flexibility
Servo motors have a wide speed regulation range and large torque output, which can adapt to different application requirements. Whether it is a situation where high-speed rotation or low-speed precision positioning is required, servo motors can provide appropriate speed and position control. This makes the robot more adaptable and flexible when facing different tasks and environments.
Improve overall performance
1. Reduce errors: The high-precision motion control capability of servo motors helps to reduce errors in the robot's motion process and improve product quality and production efficiency.
2. Reduce maintenance costs: Due to the high reliability and stability of servo motor systems, their maintenance costs are relatively low. In addition, many servo motor systems are also equipped with remote monitoring and diagnostic functions, which can further reduce maintenance costs and downtime.
In summary, robots use servo motors because servo motors can provide high-precision, high-stability, high-reliability and adaptable motion control to meet the needs of robots in various application scenarios, thereby improving the overall performance and production efficiency of robots.
