Schneider Electric SH31002P11A2000 – Hybrid stepper motor with 2000 ppr feedback for precise, repeatable positioning

The model SH31002P11A2000 appears to belong to Schneider Electric’s SH3 hybrid stepper family (heritage Berger Lahr), and—based on the suffix—includes a 2000 ppr incremental encoder for closed-loop or monitoring applications. From my experience, this combination is popular on compact indexing tables, pick-and-place tooling, labelers, and light gantry axes where you want servo-like repeatability without the complexity of a full servo system.

One thing I appreciate is how these SH3 motors typically drop right in with stepper drives like Lexium SD3, yet give you the reassurance of real position feedback. You might notice that machine builders use this model when they need stable low‑speed torque, smooth microstepping, and a clean encoder signal for fault detection or homing.

Key Features

• Hybrid stepper design – Delivers high holding torque and stable low‑speed motion; ideal for indexing and positioning.
• 2000 ppr incremental encoder – A/B/Z channels (typical) to monitor position, support homing, and enable closed‑loop stepper control.
• Clean integration with Schneider drives – Works smoothly with Lexium SD3 stepper drives and many common third‑party stepper controllers.
• Industrial build – Robust flange mounting and shielded feedback cabling reduce vibration issues and electrical noise in cabinets.
• Cost-effective precision – In many cases achieves the required repeatability without moving up to a full servo motor platform.
• Flexible wiring – Standard bipolar phase leads and separate encoder lead set make field replacement straightforward.

Technical Specifications

Related or Supporting Products

• Lexium SD3 stepper drives (Schneider) – Matched drives with multiple current ratings; microstepping and encoder-follow modes for improved stability.
• Shielded motor/encoder cable sets – Low-capacitance, foil/braid shielded harnesses reduce noise; pick lengths to suit cabinet layout.
• Planetary gearboxes (NEMA/metric interface) – When higher torque or finer positioning is needed without increasing motor size.
• Flexible shaft couplings – Zero-backlash beam or bellows couplings protect the encoder and reduce misalignment loads.
• Panel accessories – DIN-rail filters and ferrites to keep EMC in check with long encoder runs.

Installation & Maintenance

• Mounting – Rigidly mount the flange to a flat surface; align the shaft and use a zero‑backlash coupling to protect bearings and the encoder.
• Cabinet & ventilation – Keep the drive in a ventilated cabinet (IEC/UL panel standards). Stepper motors can run warm; avoid enclosing the motor without airflow.
• Wiring – Twist/route stepper phases away from low‑level encoder wiring. Use shielded encoder cable with single‑point grounding at the controller end.
• Safety – Lock out power before servicing. After wiring, verify phase order and encoder polarity before enabling torque.
• Routine checks – Inspect connectors and strain relief quarterly. Clean dust from the motor body. Verify encoder counts in the drive and re‑home axes if offsets drift.
• Firmware & tuning – If using a closed‑loop stepper drive, keep firmware current and re‑validate current limits and microstep settings after updates.
