WINGREEN 034STN1-01-300-RS – NEMA 34 Hybrid Stepper Motor with Rear Shaft for Compact Motion

The WINGREEN 034STN1-01-300-RS is a NEMA 34 hybrid stepper motor built for steady torque and repeatable positioning. From my experience, the “034” indicates the 3.4 in (≈86 mm) frame size, and the “RS” suffix points to a rear shaft version—handy when you want to add an encoder or a manual handwheel without altering the driven side. You might notice the long-body housing in the photo, which typically correlates with higher holding torque at low speed, making it a practical fit for indexing tables, feeders, and light gantry axes.

Key Features

• NEMA 34 footprint – 86 mm square face for straightforward drop‑in swaps and simple bracket reuse.
• Hybrid stepper design – 2‑phase bipolar winding for strong low‑speed torque and precise indexing.
• Rear shaft (RS) – Ready for encoder kits or a handwheel on the non‑drive end without changing your coupling.
• Microstepping friendly – Pairs well with modern stepper drives to reduce resonance and improve motion smoothness.
• Service‑oriented build – Simple wiring, robust bearings; typically runs for years with minimal attention when current limits are set correctly.

Technical Specifications

Application Fields

This model suits mid‑torque axes where repeatability and holding force matter more than top speed:

• Indexing tables and rotary actuators with precise step counts.
• Packaging feeders and labelers—microstepping keeps motion smooth and quiet.
• Light gantries, dispensers, and screw‑driven stages.
• Drop‑in replacements on existing NEMA 34 brackets without re‑machining.

A line tech told me recently, “We matched the 034STN1 code, set the driver current, and the axis held steady right away—no hunting.” That’s been typical with this footprint when the driver is sized sensibly.

Advantages & Value

• Reliability – Simple, rugged construction for 24/7 duty when thermals and current limits are respected.
• Compatibility – Works with most stepper drivers; standardized NEMA 34 mounting keeps mechanics easy.
• Cost efficiency – In many cases, meets torque/holding needs at lower system cost than a servo axis.
• Serviceability – Rear shaft simplifies encoder retrofits; swaps are fast during short maintenance windows.
• Logistics – Clear lead times and tested units support outage planning.

Installation & Maintenance

• Mounting & alignment: Use the NEMA 34 face; align couplings to minimize radial/axial bearing load.
• Drive setup: Set phase current to the motor’s rating; choose microstep resolution to balance smoothness vs. speed.
• Wiring & EMC: Twist A and B phase pairs; keep leads short; bond shields to panel ground.
• Thermal: Provide airflow; for high‑duty cycles consider a heatsink or reduce RMS current.
• Encoder (optional): Mount to the rear shaft; verify counts/rev and direction before ramping to production speeds.
• Routine care: Periodic connector/terminal torque checks, dust cleaning, and quick vibration/temperature scans during PMs.

Quality & Certifications

• Manufactured to industrial quality systems, typically aligned with ISO 9001.
• CE marking on relevant variants; many motors are UL Recognized as components.
• RoHS status depends on build generation; confirmation available by nameplate/serial.
• Warranty: 365 days repair/replace coverage from delivery.
