SCHNEIDER SM-140/20/210/P1/45/S1/B0 Servo Motor

Description

SCHNEIDER SM-140/20/210/P1/45/S1/B0 Servo Motor

The Schneider Electric (Elau) SM-140/20/210/P1/45/S1/B0 is a high-performance AC synchronous servo motor from the PacDrive SM series. Originally developed by Elau (now part of Schneider Electric), these motors are specifically engineered for high-dynamic packaging and automation machinery.

Product Detailed Description

The SM-140 is a rotary, permanently excited synchronous motor known for its high power density and precision. The alphanumeric code defines its specific hardware configuration:

• SM-140: Series name and flange size (140 mm).
• 20: Nominal speed (approx. 2000 RPM).
• 210: Peak/Stall torque related (approx. 21 Nm).
• P1: Shaft with keyway (Standard shaft with a key).
• S1: Feedback system (typically a SinCos® Hiperface single-turn encoder).
• B0: No holding brake (B1 would indicate a brake).

Technical Parameters

Product Advantages

• High Dynamism: Optimized for rapid start-stop cycles, making it ideal for high-speed packaging applications.
• Precision Control: Equipped with high-resolution feedback systems that ensure exact positioning and smooth torque delivery even at low speeds.
• Low Cogging Torque: The magnetic design minimizes torque ripple, providing superior movement quality.
• Electronic Nameplate: The integrated encoder stores motor parameters, allowing the PacDrive controller to automatically identify and configure the motor during commissioning.
• Rugged Construction: Built with Neodymium-iron-boron (NdFeB) magnets for high efficiency and resistance against winding damage.

Important Considerations (Precautions)

• Status: This specific model is largely discontinued by the manufacturer. If you are using this in a live production line, it is highly recommended to keep a refurbished or tested-surplus unit as a spare.
• Thermal Monitoring: Always connect the motor’s internal temperature sensor (PTC/KTY) to the drive to prevent permanent damage from overheating during overload conditions.
• Shaft Alignment: Precise alignment with the gearbox or load is critical; misalignment can lead to premature bearing failure or encoder errors.
• Cabling: Use original Schneider/Elau shielded cables to ensure EMC compliance and to prevent signal noise from affecting the SinCos encoder.

Product Applications

The SM-140 series is the “workhorse” of the packaging industry:

• Packaging Machinery: Used in horizontal and vertical form-fill-seal (HFFS/VFFS) machines.
• Robotics: High-speed pick-and-place arms and palletizing systems.
• Material Handling: Precision conveyor synchronization and sorting systems.
• Printing & Labeling: High-accuracy tension control and labeling application.
