Berger Lahr VRDM56450LHA – 56 mm hybrid stepper motor for precise indexing and compact machinery

The Berger Lahr VRDM56450LHA sits in the brand’s well-regarded VRDM 56 family: a compact, metric 56 mm hybrid stepper that’s typically used where tight motion control and consistent torque are required. From my experience, this size works especially well in labeling lines, dosing pumps, small conveyors, pick-and-place axes, and valve actuation—places where you want repeatable positioning without the overhead of a full servo system. You might notice that, when paired with a quality microstepping drive, it runs notably smooth at low speed and holds position firmly under load.

Key Features

• 56 mm metric flange – Fits compact machinery layouts where space is tight yet torque demand is moderate.
• Hybrid stepper, 1.8° step angle – Standard 200 steps/rev; easy to integrate with common step/direction drives.
• High holding torque for its size – Typically in the 1.2–2.7 N·m class depending on winding; ideal for indexing heads and feeders.
• Robust bearings and shaft – Designed for industrial duty cycles; accepts common couplings and gears.
• Flexible wiring options – Works with mainstream microstepping drives; 4-wire connection in many cases (A+, A–, B+, B–).
• Proven brand lineage – Berger Lahr (now under Schneider Electric) motors are known for consistent performance and long service life.

Installation & Maintenance

• Mounting and cabinet practices – Install on a flat, rigid surface. If inside a cabinet, allow airflow; stepper motors run warm in normal use.
• Wiring – Use shielded, twisted pairs for A/B phases. Keep motor cables away from high-voltage lines; ground the drive properly.
• Drive settings – Set phase current to the motor’s rated value (or slightly below for quieter operation). Enable microstepping to reduce resonance.
• Couplings and load – Use a flexible coupling; avoid side-loading the shaft. Align carefully to protect the front bearing.
• Safety – De-energize before wiring. The motor surface can get hot; add guards if it’s operator-accessible.
• Routine care – Periodically check mounting screws and couplings, clean dust from vents/area, and, if applicable, keep firmware of the external drive up to date.

A packaging OEM recently swapped a legacy 56 mm motor for a VRDM56‑series unit driven by an SD3 at 1/16 microstep. They mentioned the change shaved vibration at low speed and made indexing at 10–20 rpm feel more “servo-like” without reworking the mechanics. Results like that are typical when the drive current is dialed in and the coupling is aligned well.

Quality & Certifications

• Compliance: CE and RoHS; insulation system per IEC standards for industrial motors
• Manufacturing quality: Produced under ISO 9001 quality systems
