New Low-Noise Gearhead Models for the GPT Family© FAULHABER
Precision motion systems in laboratories, medical devices, and optical instrumentation often require high torque density while maintaining low acoustic emissions. FAULHABER has expanded its GPT family with two low-noise planetary gearheads, the 22GPT LN and 32GPT LN, developed for applications where mechanical transmission performance must be combined with reduced sound levels.
Designed for Noise-Sensitive Environments
In analytical instruments, imaging systems, and testing equipment, drivetrain noise can interfere with measurements or degrade user comfort. The 22GPT LN and 32GPT LN integrate a modified input stage with plastic gears to reduce structure-borne and airborne noise. Compared with standard GPT variants, the low-noise versions lower sound levels by up to 10 dB, a reduction that can halve perceived loudness depending on the frequency range.
The gearheads are intended for integration with high-torque DC motors in compact assemblies where space constraints limit the use of additional damping measures. This makes them relevant for developers of precision automation modules operating within a broader digital supply chain for medical and laboratory equipment.
Torque Density Within a Compact Envelope
Despite the acoustic optimization, torque output remains within the performance range expected from the GPT series. The 22GPT LN delivers up to 2.2 Nm in intermittent operation, with occasional peak torques up to 4 Nm. The 32GPT LN reaches up to 8 Nm intermittently and tolerates random peak torques up to 12 Nm.
Such torque ratings allow use in positioning systems, sample handling mechanisms, optical adjustment drives, and compact actuator assemblies where both force transmission and smooth operation are required. The planetary design supports high torque density while maintaining concentricity and transmission efficiency typical of precision gear systems.
Mechanical Robustness Across Temperature Extremes
The housings are manufactured from stainless steel, providing corrosion resistance and mechanical protection in demanding environments. The gearheads are specified for operation from –30 °C to +110 °C, enabling deployment in laboratory refrigeration units, outdoor measurement equipment, or industrial test rigs subject to temperature variation.
The drivetrain maintains efficiency during frequent or sudden load changes, which is relevant for cyclic motion profiles and start-stop applications common in test benches and automated handling systems. This stability supports consistent performance in electric motor-driven assemblies where transient loads are part of normal operation.
Positioning Within the GPT Platform
The new variants extend the existing GPT family rather than replacing standard models. Engineers can select between conventional and low-noise configurations depending on acoustic constraints, torque requirements, and system integration priorities. The underlying planetary architecture and dimensional compatibility remain consistent with the GPT platform, simplifying integration into established motion designs.
By focusing on measurable acoustic reduction without altering torque capability or operating range, the 22GPT LN and 32GPT LN address a recurring requirement in precision mechanical transmission: delivering torque in confined spaces while minimizing noise in sensitive environments.
