Typical Application Scenarios

In injection molding machines, the Kollmorgen DBL4N00950 actuates clamp toggles and ejector plates, delivering 9.5 Nm bursts to compress molds at 150 bar pressures while resolver feedback tracks plunger positions to 0.01 mm amid hydraulic pulses. In resin-rich environments with 50°C heat cycles, its sealed windings prevent contamination-induced shorts, enabling 300-second cycles that yield defect rates under 0.5%—pivotal for automotive molders meeting VDA 6.3 standards, where torque reserves cut clamp times by 10%, amplifying output from 50 to 55 shots per hour without actuator oversizing.

    • Description

    Product Introduction

    The Kollmorgen DBL4N00950 defines excellence in brushless synchronous AC servomotor technology, developed by Kollmorgen as a high-torque performer within the discontinued yet enduring DBL series for precision motion applications. This robust motor harnesses neodymium-iron-boron permanent magnets in its rotor to generate 9.5 Nm of continuous torque at 3000 RPM, delivering 2.67 kW of power from 400/480 VAC supplies, making it a go-to for dynamic axis control in automated machinery. Core functions include seamless torque amplification for acceleration ramps up to 5000 RPM and inherent self-cooling via surface fins, positioning the Kollmorgen DBL4N00950 as a mid-frame powerhouse in legacy systems where reliability trumps obsolescence. Integrated into Kollmorgen’s ecosystem, it pairs effortlessly with ServoStar amplifiers, enabling closed-loop feedback via resolver inputs for sub-arcminute positioning accuracy.

    Expanding its technical footprint, the Kollmorgen DBL4N00950 leverages a low-inertia design with 6.1 kg·cm² rotor mass, facilitating rapid response times under 1 ms in velocity profiles, while its IP64 sealing withstands coolant splashes in harsh shop environments. In broader automation frameworks, this servomotor anchors multi-axis gantries by providing consistent stall torque without cogging, compliant with EN 60034-1 standards for electromagnetic compatibility. The Kollmorgen DBL4N00950 delivers strategic value through its standardized flange mounting, which simplifies retrofits into existing NEMA-compatible frames, reducing engineering hours by up to 25%.

    Ultimately, the Kollmorgen DBL4N00950 embodies Kollmorgen’s heritage of motion mastery, where enduring performance intersects with practical scalability. For facilities maintaining legacy lines or seeking cost-effective upgrades, it ensures sustained throughput, transforming potential spares challenges into opportunities for optimized kinematics.

    Core Advantages and Technical Highlights

    Torque Density and Dynamics: The Kollmorgen DBL4N00950 achieves peak torque of 28.5 Nm—three times its continuous rating—for 5-second bursts, driven by a distributed winding stator that minimizes harmonic distortion below 1%, ensuring smooth operation at speeds up to 5000 min⁻¹ without resonance amplification. This high dynamic range supports acceleration torques exceeding 100 rad/s², ideal for pick-and-place cycles where inertia matching to loads up to 20 kg preserves energy efficiency at 92% across 20-80% duty.

    Thermal Resilience and Efficiency: With a 2.67 kW rating at 400 VAC, the Kollmorgen DBL4N00950 employs Class F insulation and oversized windings to handle 150% overloads at 40°C ambients, dissipating heat via a 1.2 m² finned housing that limits surface temps to 90°C. Resolver feedback maintains commutation accuracy within 0.5 electrical degrees, while back-EMF optimization recycles regenerative energy, cutting amplifier sizing needs by 15% in decelerative profiles as confirmed in cycle testing.

    Rugged Construction for Longevity: The Kollmorgen DBL4N00950‘s aluminum housing with j6 shaft tolerances endures 10 G shocks per IEC 60068-2-27, backed by a 6.5 kg lightweight frame that eases integration into overhead robots. IP64-rated seals on shaft and connectors repel oil mists up to 0.1 bar, yielding MTBF over 50,000 hours in 80% humidity, with vibration damping inherent to its skewed rotor slots reducing audible noise to 65 dB at full load.

    Seamless Compatibility Ecosystem: Flange dimensions per DIN 42955 align the Kollmorgen DBL4N00950 with legacy AKM series mounts, supporting direct swaps via standard resolvers or optional Hiperface encoders for 1024 ppr resolution. It interfaces with Kollmorgen’s AKD drives via SFD protocol for auto-tuning, enabling plug-and-play in CANopen networks up to 1 Mbit/s, which streamlines multi-motor synchronization without custom cabling.

    Intuitive Integration Tools: Shaft keys and anti-rotation pins facilitate torque arm setups, while embedded temperature sensors (PTC 130°C trip) integrate with PLC safeties for predictive shutdowns. The Kollmorgen DBL4N00950‘s documentation includes CoE object dictionaries for EtherCAT, accelerating commissioning with Kollmorgen WorkBench software that profiles inertia in 2 minutes, slashing setup variances by 30% in field deployments.
