Product Description (Detailed Explanation)

The Lexium SH3 series represents Schneider Electric’s premium range of brushless servo motors. This specific model features a 140mm flange size and is optimized for applications requiring high inertia and significant peak torque.

The motor uses rare-earth magnets to achieve a compact footprint while maintaining high efficiency. The modular nomenclature of the part number defines specific hardware features, including the winding type (optimized for 2000-4000 RPM), a smooth shaft (no keyway), and integrated high-resolution feedback. It is built to withstand rigorous industrial cycles with frequent starts, stops, and reversals.

Product Parameters (Technical Specifications)

Product Advantages (Key Benefits)

• High Torque Density: Delivers exceptional torque relative to its frame size, allowing for more compact machine designs.

• Low Cogging Torque: Engineered for smooth rotation even at very low speeds, which is critical for high-precision finishes in CNC or printing applications.

• Robust Thermal Management: Features optimized heat dissipation through the aluminum housing, ensuring long-term reliability during continuous duty cycles.

• High Dynamic Performance: Low rotor inertia allows for extremely fast acceleration and deceleration ramps, increasing overall machine throughput.

• “Smart Process” Compatibility: When used with Lexium drives, the motor’s electronic nameplate is automatically recognized, simplifying commissioning and parameter tuning.

Precautions (Important Notes)

• Shaft Alignment: Since this is a Smooth Shaft (P1) model, ensure that the coupling used is a high-quality friction-lock or compression type. Improperly tightened couplings will slip under high acceleration.

• Radial/Axial Loads: Avoid exceeding the maximum permissible forces on the shaft. Excessive belt tension or direct-drive misalignment can lead to premature bearing failure.

• Cabling: Use only shielded Schneider Electric power and encoder cables. High-frequency switching from the drive can cause interference in unshielded signal lines, leading to “Encoder Fault” alarms.

• Thermal Protection: Connect the integrated temperature sensor (PTC/KTY) to the drive’s thermal monitoring input to prevent winding burnout in case of an overload or cooling failure.

Product Applications (Typical Use Cases)

• Packaging Machinery: Controlling high-speed “pick-and-place” robots or heavy-duty film unwinding stations.

• Material Handling: Powering vertical axes in automated storage and retrieval systems (ASRS) where high torque is required to lift loads.

• Metal Working: Used in feed axes for CNC milling machines or heavy-duty press-feed systems.

• Printing & Converting: Driving large rollers where synchronized speed and precise tension control are mandatory.

• Automotive Assembly: Operating high-torque nut runners or robotic welding positioning tables.
