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

The WINGREEN 034STN1-01-300-R is a NEMA 34 class hybrid stepper motor aimed at high-torque, repeatable positioning. Based on the code pattern, “034” points to the 3.4 in (≈86 mm) frame size, while the “R” suffix indicates a rear shaft—handy for encoder retrofits or a manual handwheel. From my experience, motors in this format drop neatly into packaging axes, index tables, and small gantries where you want firm holding torque without the complexity of a full servo loop. You might notice the long-body housing in the photos, which typically translates into higher torque at low speed.

Key Features

• NEMA 34 footprint – 86 mm square face makes drop‑in swaps straightforward on existing brackets.
• Hybrid stepper design – 2‑phase bipolar winding for strong low‑speed torque and precise index moves.
• Rear shaft (R) – Convenient for encoders or a manual knob without changing the driven-side mechanics.
• Smooth microstepping – Works well with modern stepper drives to reduce resonance and improve surface quality.
• Service-friendly – Simple wiring and robust bearings; in many cases it runs for years with only periodic checks.

Technical Specifications

Application Fields

You’ll typically find this motor on mid‑torque axes where repeatability and holding force beat raw top speed:

• Indexing tables and rotary actuators that need firm detent and accurate step counts.
• Packaging lanes and feeders—microstepping helps keep motion smooth and quiet.
• Light gantries and dispensers driven by belts or ball screws.
• Drop‑in replacements for existing NEMA 34 footprints without re‑machining brackets.

A maintenance tech told me last week, “We matched the 034STN code, set the driver current, and the axis held steady immediately—no hunting, no fuss.” That mirrors what I usually see with this frame size.

Advantages & Value

• Reliability – Simple, rugged build for 24/7 operation when the drive current is set correctly.
• Compatibility – Works with most stepper drivers; NEMA 34 mounting keeps mechanical changes minimal.
• Cost efficiency – In many cases a stepper meets torque needs at lower system cost than a servo.
• Serviceability – Rear shaft eases encoder retrofits and quick field swaps during short maintenance windows.
• Delivery assurance – Predictable lead times help you hit outage or FAT dates.

Installation & Maintenance

• Mounting & alignment: Use the NEMA 34 face; align coupling to minimize radial/axial load on bearings.
• Drive setup: Set phase current to the motor’s rating; choose microstep resolution to balance smoothness and speed.
• Wiring & EMC: Twist A and B phase pairs; keep leads short; bond shields to panel ground to cut noise.
• Thermal: Provide airflow; consider a small heatsink or lower RMS current for long high‑duty cycles.
• Encoder (optional): Mount on the rear shaft; verify counts/rev and direction in the controller before ramping up speed.
• Routine care: Check connector/terminal torque, clean dust quarterly, and review vibration/temperature trends during PMs.

Quality & Certifications

• Manufactured to industrial quality standards, typically aligned with ISO 9001 practices.
• CE marking on relevant variants; many motors are UL Recognized as components.
• RoHS compliance depends on build series; we can confirm by nameplate/serial.
• Warranty: 365 days repair/replace coverage from delivery.
