Improve Accuracy: By providing precise position data, feedback devices enable the control system to make minute adjustments, ensuring accurate and consistent movement.

Enhance Stability: Feedback devices help detect and correct deviations in real-time, minimizing vibrations and oscillations and ensuring smooth operation.

Facilitate Diagnostics: Real-time feedback helps diagnose performance issues, allowing for quick corrective action and reducing downtime.

5. Regularly Inspect and Maintain the Motor

Regular inspection and maintenance are crucial to optimizing the performance of linear motors. Maintenance tasks should include:

Inspecting Cables and Connectors: Check for wear, fraying, or damage to cables and connectors, and replace them as needed to prevent electrical issues.

Checking Alignment: Ensure that the motor and load are properly aligned to avoid excessive wear and maintain smooth motion.

Monitoring for Wear and Tear: Regularly inspect the motor components, such as bearings and rails, for signs of wear. Promptly address any issues to prevent further damage.

6. Use Simulation and Modeling Tools

Utilize simulation and modeling tools to analyze the performance of linear motors in your specific application. These tools can help you:

Predict Motor Behavior: Understand how the motor will perform under various conditions, such as different loads, speeds, and temperatures.

eBook - Thomson Electrac HD Linear Actuator Motion Control per CAN Bus

The Electrac series of actuators supports two higher-layer protocols based on Controller Area Network (CAN): CANopen, and SAE J1939. You can control the actuators merely with hardware switches (Start, Stop, Forward Motion, Backward Motion), but, in addition, both CAN protocols allow to regulate the linear speed. I dare say, in view of various undocumented eccentricities, I cannot recommend programming the Electrac per CAN/J1939 without reading this document.
