Application case of integrated servo motor in controlling the rotation of turntable in automatic wel
Application scenarios
During the welding process, the accuracy and stability of the rotating part of the turntable are crucial to the welding quality. Traditional motors are prone to jamming when running at low speeds, and the control accuracy is insufficient when running at high speeds, making it difficult to meet the needs of complex welding processes. Therefore, customers choose an integrated servo motor to improve the control accuracy and dynamic performance of the turntable rotation.
Selected models and functions
Core model: PMM8075B-485-C-0HE-02
Key functions:
•Profile speed mode: Achieve high-precision control of the turntable rotation speed to ensure the accuracy and consistency of the welding trajectory.
•High torque output: Provide stable torque output under low speed or heavy load conditions to avoid jamming.
•Communication interface: Support RS-485 communication protocol, which is convenient for integration with the control system to achieve remote monitoring and fault diagnosis.
Problems and challenges
1. Low-speed jamming: Without a reducer, the motor jams when the speed is lower than 60rpm, affecting the welding accuracy.
2. Motor does not rotate: After installing a 1:3 reducer, the motor cannot operate normally, resulting in interruption of welding operations.
3. Power matching: Ensure that the power of the power supply matches the motor load requirements to avoid power shortage or overload problems.
Solution
1. Reducer selection and installation:
For the problem of low-speed jamming, select a suitable reducer (1:3 reducer) and optimize the installation of the reducer and the integrated servo motor to ensure that the motor can drive the turntable smoothly.
Accurately calibrate the reducer to reduce transmission errors and improve the rotation accuracy of the turntable.
2. Power optimization:
According to the motor load requirements, select the appropriate power supply to ensure that the motor can operate stably under high speed, low speed and heavy load conditions.
Add power overload protection function to avoid motor damage due to overload.
3. Motor control optimization:
Enable the contour speed mode to achieve high-precision control of turntable rotation by accurately controlling the motor speed and acceleration.
Intelligent control algorithms are introduced to dynamically adjust motor parameters according to welding process requirements to improve welding quality and efficiency.
Application effect
1. Improved welding accuracy: The turntable rotation accuracy is improved to ±0.05°, the welding trajectory consistency reaches 99%, and the welding quality is significantly improved.
2. Improved production efficiency: The motor runs stably without jamming and overload, and the continuity and efficiency of welding operations are improved by 20%.
3. Reduced maintenance costs: The optimized motor and reducer combination reduces the failure rate and reduces the equipment maintenance cost.
Case summary
By adopting an integrated servo motor, the accuracy and stability problems of the turntable rotation part in the automatic welding equipment were successfully solved. Through the selection and installation of the reducer, power optimization, and motor control optimization, high-precision control and stable operation of the turntable rotation are achieved. This case provides a technical solution for the automatic welding industry, fully demonstrating the technical advantages and application value of integrated servo motors in complex industrial scenarios.
