The impact of electromagnetic interference on servo electric cylinders and solutions
In industrial automation systems, servo electric cylinders are one of the key components, but when faced with electromagnetic interference, the following problems may occur:
- Increased position error: Electromagnetic interference may cause an increase in the position control error of the servo electric cylinder, affecting the accuracy and stability of the system.
- Motion instability: Interference may cause instability in the movement of the electric cylinder, manifesting as speed fluctuations or oscillations, affecting production efficiency and quality.
- System crash: Severe electromagnetic interference may cause the servo electric cylinder system to crash, requiring restarting or repair, causing production interruption.
Solution:
- Shielding design: Use an effective shielding design around the servo electric cylinder, including shielding layers for cables and equipment housings, to minimize the impact of external electromagnetic fields on the system.
- Cable layout: Plan the cable layout rationally to avoid cables crossing within the system and reduce electromagnetic induction. Use shielded cables to ensure their quality and performance meet requirements.
- Application of filter: Installing a power filter can effectively suppress high-frequency noise on the power line and ensure the stability of the servo electric cylinder system.
- Isolate sources of interference: Isolate potential sources of electromagnetic interference to reduce their impact on the servo electric cylinder system. This can be achieved through physical isolation or the use of shielding equipment.
- Electromagnetic compatibility testing: Electromagnetic compatibility testing is performed during the design and manufacturing stages to ensure that the servo electric cylinder can operate normally under various environmental conditions.
