Kollmorgen E33NCHA-LNN-NS-00 Stepper Motor – Precision Motion for Industrial Automation

The Kollmorgen E33NCHA-LNN-NS-00 is part of Kollmorgen’s industry-proven stepper lineup, designed for repeatable positioning, smooth microstepping, and minimal maintenance in demanding environments. From my experience, this model is favored when teams need predictable torque at low to mid speeds without the complexity of servos. You might notice that it pairs well with modern microstepping drives, giving tight positioning control for indexing tables, pick-and-place axes, labeling lines, and light-duty gantries.

Application Fields

This model suits repeatable, moderate-speed axes where holding torque and simplicity are key. Typical placements:

• Electronics assembly: screwdriving, PCB depaneling, feeders
• Packaging & labeling: index wheels, label applicators, film feeders
• Light-duty gantries and XY tables: pick-and-place, testing fixtures
• Medical & lab automation: peristaltic pumps, positioning jigs (with proper guarding)
• Textile, printing, and small conveyors requiring precise step indexing

Advantages & Value

• Reliability – Kollmorgen’s windings and bearings typically outlast budget alternatives in high-duty cycles.
• Compatibility – Works smoothly with mainstream stepper drives (Kollmorgen P7000 series, and most step/direction drives).
• Cost control – Open-loop architecture often delivers the needed accuracy without encoder costs.
• Support – Documentation, torque curves, and quick guidance on tuning microstep/accel settings.

A fixture builder told us, “We swapped a servo for the E-series stepper on an indexing wheel. Same throughput, lower cost, and it’s been hands-off for a year.”

Installation & Maintenance

• Mounting – Bolt the motor to a rigid, flat surface. Align the shaft carefully; use flexible couplings to avoid radial/axial stress.
• Wiring – Use shielded motor cable to the drive. Keep motor power cables separated from signal wiring to reduce EMI.
• Drive & enclosure – Place the stepper drive in a ventilated control cabinet (typical 24–80 VDC supply). Follow the drive’s bonding/grounding practices.
• Tuning – Set microstep resolution and current limit per the winding data. Add acceleration ramps to reduce mechanical shock.
• Routine checks – Inspect couplings, belts, and connectors quarterly; clean dust from vents; verify fasteners and re‑torque if needed.
• Thermal considerations – The motor case can run hot under load; ensure surrounding components tolerate elevated surface temperatures.

Quality & Certifications

• CE and RoHS compliant (manufacturer series level)
• UL Recognized component (typical for Kollmorgen stepper families)
• Produced in ISO 9001–certified facilities
• Manufacturer’s warranty: 12 months (365 days)

Commonly Paired Components (Optional)

• Kollmorgen P7000 series stepper drives (e.g., P70530) for smooth microstepping and anti-resonance control
• Precision gearheads and flexible shaft couplings sized to the motor shaft
• Shielded motor cables and 24–80 VDC power supplies sized for the drive and duty cycle

If you’re standardizing across lines, this model seems to hit a sweet spot: dependable torque, straightforward integration, and predictable lead times. Tell me your required speed/torque point and drive voltage, and I’ll match the winding and drive settings so it runs right the first time.
