In many cases, encoders can be integrated into all three SMLA configuration types (MLS, MLN and MLA). Only a flat surface is required to bolt the encoder body onto and a shaft on which to mount the optical disk. The shaft must be an extension of the original motor shaft so that the optical disk can rotate with it to capture the motor’s motion accurately.

Stepping up While open-loop SMLA systems are suitable for many applications, stepper motor users wanting real-time feedback on load position should consider adding encoders to their motors. Encoders can provide position feedback, real-time data on speed, direction and other characteristics, while improving control and monitoring of the load. For basic positioning feedback, users should specify incremental encoders, but if high precision is required or the ability to maintain position once the equipment is powered on, they should consider absolute encoders. Closing the feedback loop with optical rotary encoders not only meets the demands of today's precision applications but also positions SMLAs as valuable components in the evolving landscape of Industry 4.0 and digital connectivity innovation, ensuring their continued relevance and effectiveness in the next generation of industrial automation.
